Answer: srry if this doesn't help.......

wut equation, is it:

Ashley solves the equation 0.4(2.5 x - 8) - 4 and claims that the solution is x - -0.8. The table below shows the steps she took and the reasons for each step.

Step 1

Equation

0.4(2.5 x-8)= -4

X-32=-4

x - 32+3.2 = -4 +32

x=-08

Reason

Given

Associative Property

Addition Property of Equality

Subtraction Property of Equality

Determine whether each statement below is true or false regarding the reasons given in the table. Select True or False for each statement.

True False

The reason for Step 1 is correct

The reason for Step 1 should be the Distributive Property

The reason for Step 2 is correct

The reason for Step 2 should be the Additive Identity Property

The reason for Step 3 is correct

The reason for Step 3 should be Additive Inverses Property and/or Combining Like Terms

Explanation:

The reason for Step 1 is correct. False

The reason for Step 1 should be the Distributive Property. True

The reason for Step 2 is correct. True

The reason for Step 2 should be the Additive Identity Property. False

The reason for Step 3 is correct. False

The reason for Step 3 should be Additive Inverses Property and/or Combining Like Terms. True

Explanation:

Distributive Property: a(b + c) = ab + ac

Addition property of equality: if x = y then x + a = y + a

Subtraction property of equality: if x = y then x - a = y - a
