What number makes the expressions equivalent?
1/2(-1.4m+0.4)=?m+0.2

– 0.7

Step-by-step explanation:

Given expression is  

To simplify this expression   we get equivalent expression.

Multiply and Divide the expression by two.

To simplify the expression again, we get,

⇒ (–0.7 m + 0.2)

So, we found the coefficient of m is –0.7.

The missing number is –0.7  

Hence, –0.7 makes the expression equivalent.

Therefore,   = –0.7 m + 0.2.

yo answer should be 6 if im not mistaken
