Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Follow the steps to simplify the left side of the equation by using the distributive property and combining like terms.
1. Distribute the 2:    7.8 + 1.5m + 0.8
2. Combine like terms:  8.6 + 1.5m
Use the same steps to simplify the right side of the equation.
What would it simplify to?

a. -8.4m - 0.8
b. -4.4m - 0.8
c. -4.4m - 3.2

Answer 1

Answer:

c.) -4.4m - 3.2

Step-by-step explanation:

We can do this to simplify the left side!

$-6.4m + 4(.5m - .8)\\-6.4m + 2m - 3.2\\-4.4m - 3.2$\

We are left with the following expression!

-4.4m - 3.2!

Answer 2

Answer:

D -4.4m-3.2

Step-by-step explanation:

Consider this equation.

7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)

Follow the steps to simplify the left side of the equation by using the distributive property and combining like terms.

1. Distribute the 2:    7.8 + 1.5m + 0.8

2. Combine like terms:  8.6 + 1.5m

Use the same steps to simplify the right side of the equation. What would it simplify to?

✔ –4.4m – 3.2
