9/? = 25/100. First you multiply 100•9 and you get 900, then you divide 900 divided by 25, and you get 36. So the answer is 36

So because 25%=1/4 we would know to multiply 9*4
Which would get our answer to be 36 :)

Y = 3/2x + 5/4 −2x + 8y = −25

Andreyy89

Answer:

Step-by-step explanation:

When solving algebra, it is important the we follow the steps in correct order and check our answer at the end.

Step 1: Simplify by combining like terms

y = -x/2 + 5/4 + 8y = -25

Step 2: Substitute

y = -25

-25 = -x/2 + 5/4 + 8(-25)

-25 = -x/2 + 5/4 + -200

-25 = -x/2 - 198 3/4

Step 3: Answer

x = -347 1/2

Step 4: Check

y = 3/2x + 5/4 −2x + 8y = −25

-25 = 3/2(-347 1/2) + 5/4 −2(-347 1/2) + 8(-25)

-25 = -25✔️

Step 5: Verified Answer

x = -347 1/2

I'm always happy to help :)
