Answer:
Weighted average is the average of a set of numbers, each with different associated “weights” or values. To find a weighted average, multiply each number by its weight, then add the results.
Step-by-step explanation:
-5m-20-80+50m=0
45m=100
m= 20/9
-2y + 6 < 10
Subtract 6 on both sides
-2y < 10
Divide by -2 on both sides
y > -5
