Write two equivalent fractions for each. 1/2 and 4/5

An equivalent fraction for 1/2 would be 2/4. This is because you can simplify 2/4 by dividing it by 2. The final answer would be 1/2.

An equivalent fraction for 4/5 would be 8/10. It's basically the same thing. Divide them both by 2 and you'll get 4/5 since 8 divided by 2 is 4, and 10 divided by 2 is 5.

Is 3/4 equivalent to 12/15

For this, you have to reduce the larger fraction, which is 12/15
After reduction, it would be: 4/5 which is not equivalent to 3/4

4/5 ≠ 3/4

So, your final answer is "NO", it's not equivalent

Explain why 3(5x) is not equivalent to (3*5)(3*x).

Wow. Ok, really simple, honestly. Because 3(5x) = 15x. (3*5)(3*x) = 3*5 = 15*3 = 45x. Therefore, 15x and 45x do not correspond to each other at all, meaning that 3(5x) is not equivalent to (3*5)(3*x)!!!

Express the equation -6a+2b=8 as an equivalent equation that is solved for b (steps please)

-6a+2b=8
add (6a) to both sides
-6a +2b+6a = 8 +6a
simplify
2b = 8+ 6a
divide both sides by 2
2b/2 =(8+6a)/2
simplify
b= 8/2 + 6a/2
b=4 +3a
or 
b=3a+4

1. Which fractions are equivalent to 25/45. Please give two examples. 2. Which describes independent events? Spinning two fours on a spinner divided into four numbered sections. Selecting two kings from a standard deck of cards by choosing a card at random, placing it in your pocket, then choosing the second card. Selecting two green marbles by choosing one from a bag at random, giving the first to a friend, then choosing another. Selecting the names of two siblings by choosing slips of paper from a hat at random, pinning the selected slip on a bulletin board, and then selecting another.

1) fractions equivalent to 25/45

Any fraction obtaining by multiplying both numerator and denominator by the same quantity will result in an equivalent fraction.

Examples:

- divide both numerator and denominator by 5 => 5/9 is equivalent

- multiply both numerator and denominator by 2 => 50 / 90 is equivalent

- multiply both numerator and denominator by 10 => 250 / 450  is equivalent.


2)
Spinning two fours on a spinner divided into four numbered sections: these are independent events, becasue one result does not influence the other.

Selecting two kings from a standard deck of cards by choosing a card at random, placing it in your pocket, then choosing the second card: they are not independent, because if the first card is a king the probability of the second card will be different than if the first card is not a king.

Selecting two green marbles by choosing one from a bag at random, giving the first to a friend, then choosing another: they are not independent because whether the first two marbles are green or not, make the probabilities for the second event different.

Selecting the names of two siblings by choosing slips of paper from a hat at random, pinning the selected slip on a bulletin board, and then selecting another.: they are not independent, by similar reason explainded in the two previos options.

Which of the following is an equivalent form of the compound inequality −22 > −5x − 7 ≥ −3? −5x − 7 < −22 and −5x − 7 ≥ −3 −5x − 7 > −22 and −5x − 7 ≥ −3 −5x > −22 and −7 ≥ −3 −5x − 7 < −22 and −5x − 7 ≤ −3

The answer is: [A]: " −5x − 7 < −22 and −5x − 7 ≥ −3 "
______________________________________________
Explanation:
___________________________
We are the given the following compound inequality:
__________________
−22 > −5x − 7 ≥ −3 "
__________________________
Consider Answer choice: [A]: 
−5x − 7 < −22 and −5x − 7 ≥ −3
____________________________________________
Do both of these given in "Answer choice [A]" hold true?
______________________________________
  First, does: 
−5x − 7 < −22 hold true?  
___________________________________
Yes, because, in the compound inequality given:
___________________________________
−22 > −5x − 7 ; which is another way of saying that:
 __________________
 
−5x − 7 < −22 .
____________________
Second does: 
 "−5x − 7 ≥ −3 " , hold true?
_____________________________
Yes, because, in the compound equality given, 
________________
−5x − 7 ≥ −3 ; which explicitly tells us that it holds true.
_________________
Thus, "Answer choice: [A]: −5x − 7 < −22 and −5x − 7 ≥ −3 " is a correct answer.
___________________
There could be other correct answers, so let us examine the other answer choices:
____________________
Consider "Answer choice: [B]: 
−5x − 7 > −22 and −5x − 7 ≥ −3 ;
__________________________
Do EACH of these hold true in "Answer choice "B"?
_______________
First let's examine:
_________________
 −5x − 7 > −22 ; Does this hold true?
_____________________
No! Because in the compound inequality given,
−5x − 7 < −22 ; so we already know that "Answer choice: [B]" is incorrect; and thus, it makes no difference whether the other part of "answer choice [B]" is correct or incorrect.
_______________________
Let us consider: "Answer choice: [C]: 5x > −22 and −7 ≥ −3" .
 Do these hold true with respect to our given compound inequality?
____________________________________________________
No; since NEITHER one of of this 2 (two) components given are are part of our compound inequality given.
__________________________________________________
Furthermore, the particular component given: " 
−7 ≥ −3" does not make sense. "Negative 7" is not 'greater than or equal to' "Negative 3".   -7 ≠ -3 . Additionally, "-7" is LESS THAN—not GREATER THAN—"-3". 
_________________________________________________
Also, "−5x > −22" is NOT part of the compound inequality given. So, "Answer Choice: [C]:  −5x > −22 and −7 ≥ −3" ; is INCORRECT.
___________________________________________________
Additional note: "
 −5x < −22" is NOT part of the compound inequality given, either.
____________________
The [incorrect] "Answer Choice: [C]:  "−5x > −22 and −7 ≥ −3" ; can be somewhat deceptive.

The compound inequality given:
___________________________
" −22 > −5x − 7 ≥ −3 "  ;   should be viewed as:
_______________________________________
" −22 > (−5x − 7) ≥ −3 " ;
_____________________________________
and the term, "(−5x − 7)" should be treated as one separate term—just like the terms: "(-22)", and "(-3)".
_______________________________________________
Let us consider "Answer choice: [D]: −5x − 7 < −22 and −5x − 7 ≤ −3 " .
_______________________________________________
Start with: 
−5x − 7 < −22 .  Does this hold true for our original compound inequality? 
________________
Yes!  (Since in our original compound inequality; "−22 > −5x − 7" ;
 and this component of 'Answer choice: [D]' — "−5x − 7 < −22 "— is another way of saying that: "−22 > −5x − 7" (as denoted in our original compound inequality).
___________________
Now, we shall examine the second component of
'Answer choice: [D]' — "−5x − 7 ≤ −3 ".
_____________________
D
oes this hold true for our original compound inequality? 
_______________________
No!  This second component given in our 'Answer choice'—is:
 "-5x − 7 ≤ −3" ; and in our original compound inequality: 
_______________
"
−5x − 7 ≥ −3 " ! 
________________________
As such, since one of the compounds in 'Answer choice: [D]' is incorrect; 
 _______________________________________________
Answer choice: [D]: "−5x − 7 < −22 and −5x − 7 ≤ −3" ;  is incorrect.

Each week, Diana spends 4 hours playing soccer and 6 hours babysitting. Which ratio is equivalent to the ratio of the time Diana spends playing soccer to the time she spends babysitting?

The ratio is whatever is said first if that makes sense, so what was said first is that Diana spends 4  hours playing soccer to Diana spending 6 hours babysitting. That would be 4/6 (four over six). To find what is equivalent you  need to simplify that which would give you 2/3 (two over three) 

Let me know if you need more help!

Help please 11 POINTS PLEASE HELP I DON'T UNDERSTAND. PLUS I WILL MARK BRILLIANT WHO ANSWERS ALL OF THEM CORRECTLY. 1) Rename 4/7 as a percent. Round to the nearest tenth of a percent if necessary 2) Rename .709 as a percent 3) If 1/3 is equivalent to 33 1/3 %, what percent is equivalent to 2/3? 4) Alice plays basketball. In one game she shoots 21 free throws and makes 81.25% of them. Estimate how many free throws she makes? 5) Estimate 48% of $23.95 6) The bill at a restaurant is $58.50, and Mrs. Johnson wants to leave a 15% tip. Approximately how much money should she leave? 7) Which proportion can be used to solve the following percent problem? What is 50% of 70? 8) What percent of 50 is 12.5? 9) 50 is 6.25% of what number?

1) Convert fraction into a decimal: 4 / 7 = 0.5714... Round to nearest tenth. The 5 is in the tenth place. Look at the digit on the right of 5. Is it equal or greater than 5? Yes. 7 is greater than 5. We round up to 0.60. Convert decimal to percent: 0.60 => 60%

2) Just move the decimal point two places to the right: 0.709 => 70.9%

3) We know that 1/3 is equal to 33 1/3%. Just multiply 33 1/3% by two.

0.333... * 2 = 0.6666... = 66 2/3%

4) Alice gets 21 free throws and makes 81.25% of them. The question then asks "how many free throws she makes". Well just multiply 81.25% by 21:
0.8125 * 21 ≈ 17

5) Convert percent into decimal: 48% => 0.48
Multiply: 0.48 * 23.95 ≈ $11.50

6) Multiply 15% by 58.50: 0.15 * 58.50 ≈ $8.80

The last three questions I answered in your other question.
