Answer:
m = 90
Step-by-step explanation:
Hi,
To begin, you have to isolate the variable, m, meaning that we have to first, subtract 12 on both sides.
-2/9m = -20
Now, instead of dividing by -2/9, we can multiply -20 by -9/2 to find m. (All you have to do is flip the fraction). When we do this...
-20/1 x -9/2 = 180/2 = 90
m = 90
I hope this helps :)
Answer:
M = 90
Step-by-step explanation:
1) Simplify 2/9m to 2m/9.
[tex] - \frac{2m}{9} + 12 = - 8[/tex]
2) Subtract 12 from both sides.
[tex] - \frac{2m}{9} = - 8 - 12[/tex]
3) Simplify - 8 - 12 to -20.
[tex] - \frac{2m}{9} = - 20[/tex]
4) Multiply both sides by 9.
[tex] - 2m = - 20 \times 9[/tex]
5) Simplify 20 × 9 to 180.
[tex] - 2m = - 180[/tex]
6) Diving both sides by -2.
[tex]m = \frac{ - 180}{ - 2} [/tex]
7) Two negative makes a positive.
[tex]m = \frac{180}{2} [/tex]
8) Simplify 180/2 to 20.
[tex]m = 90[/tex]
Hence, the answer for m is m = 90
