Answer:
m = 11, and the correct equation is m + 7.28 = 18.28
Explanation:
First, we need to solve:
0.2*m = 2.20
To do it, we need to divide by 0.2 in both sides:
0.2*m/0.2 = 2.20/0.2
m*(0.2/0.2) = 11
m = 11
Ok, we know the value of m.
Now we need to input the value of m in each one of these 4 equations and see which one is the correct one.
The correct equation is;
m + 7.28 = 18.28
When we replace m by 11, we get:
11 + 7.28 = 18.28
So the equation is correct.
