What would you divide the numerator and denominator by to put 16/24 in simplest form?

Answers

Answer:

You would divide both by 4

Step-by-step explanation:

16 and 24 are both multiples of 4.

Answer:

8

Step-by-step explanation:

To answer this question, you need to find the common factors of each number. The factors of 16 are 1, 2,4, 8, and 16. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. You then have to find the greatest common factor. In this case, it would be 8.  

Solve the following equation:
15(x-3)/5 = 3 (2x - 3)

x = ?

Answers

Answer:

x=0

if u wat step by step answer just tell me n ill do it

Answer:

0

Step-by-step explanation:

15(x-3) / 5  =  3(2x-3)

Distribute

(15x - 45) / 5  =  6x - 9

Multiply both sides by 5

15x - 45  =  (6x-9) x 5

Distribute

15x - 45  =  30x - 45

Gather the x's one side, and the other numbers on the other

-15x = 0

x = 0

A. 125x + 35 = 750; x = 5.75
B. 35 - 7.5x = 125; x = 6
C. 7.5x + 35 = 125; x = 12
D. 35x + 125 = 750; x = 18

Answers

Answer:

C

Step-by-step

Answer:

Answer is C

Step-by-step explanation:

First Jackie needs to save $125

y = 125

He already saved $35, this is our constant

He makes $7.50 an hour on his job,

Our variable x is hours

125 = 7.50x + 35

If we solve for x, we get x = 12

Lin baked 36 cookies. She gave some cookies to Kiran. She had 26 left. Select all the equations that represent this situation.
k = 36 - 26

36 - k = 26

26 - k = 36

36 = 26 + k
This is my cousin's h.w and it's due tomorrow so PLS help!

Answers

Answer:

36 - k = 26

Step-by-step explanation:

Lin started out with 26 cookies, and then she gave an unknown amount to Kiran, and was left with 26, so 36 - k = 26

Answer:

First, second and fourth.

Step-by-step explanation:

k could represent the number of cookies given to Kiran.

The first one is true, Lin gave 36 - 26 cookies to Kiran.

The second one is also true, Lin had 26 cookies remaining after she gave some to Kiran.

The third one is false, 26 - the amount Lin gave is not 36.

The fourth one is true, 36 is equal to the amount remaining plus the amount given to Kiran.

Hope this helps!
