NEED HELP

Combine like terms to create an equivalent expression. 7/8 * m + 9/10 - 2m - 3/5

Answer 1

Answer: Hope this helps you!

-9/8m + 3/10

Explanation:

I will start off with the equation

7/8 * m + 9/10 - 2m - 3/5

Now I'm going to subtract 9/10 from 3/5 (6/10)

7/8 * m + 3/10 - 2m

Now I'm going to multiply 7/8 * m which is equal to 7/8m

7/8m + 3/10 - 2m

And I will lastly subtract 2m from 7/8 and the answer is:

-9/8m + 3/10

Answer 2

like terms are = 1) 7/8 * m and -2m

2) 9/10 and -3/5

-2m = -16/8 * m

(7/8 - 16 / 8) m = -9/8 *m

-3/5 = -6/10

9/10 - 6/10 = 3/10

the answer will be = (-9/8)* m + (3/10)
