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

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
