Paula used these steps to solve an equation:
step 1: -4(7 + 8) - 21 = 25
step 2: -4r – 32 - 2x = 25
step 3: -61 – 32 = 25
step 4: -6x = 57
step 5: x = -95
between which two steps did paula use the division property of equality?

Between step 4 and step 5

Step-by-step explanation:

The Division Property of Equality states that when both sides of an equation are divided by the same nonzero number, both sides remain equal.

That is, if a, b, and c are real numbers such that a = b and c ≠0, then  

At step 4: The equation was -6x = 57

To move to step 5, Paula had to divide both sides by the co-efficient of x (-6) in order to get the value of x. See below

---- Divide both sides by -6 (Step 4)

---- (Intermediary between step 4 and 5)

----- Step 5

Hence, we can conclude that the division property of equality was done between step 4 and step 5

.

step-by-step explanation:

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
