Question

12(−1.4m+0.4)=

0.7m + 0.2


-0.7m + 0.2


2.8m + 0.8


-2.8m + 0.8

Answer 1

m = 0.28571428571

or 0.29(to the nearest tenth)

Explanation:

First, distribute

12(−1.4m+0.4)=

-16.8m + 4.8 =

Now move the constant to the right.

-16.8m + 4.8 =

-16.8m = -4.8 =

Now divide,

-16.8m = -4.8 =

m = 0.28 or 0.29
