To find the average, you have to add all the numbers up and then divide by the amount of numbers you added together.
Equation: (86+87+91+x)/4=98
Solve for x:
86+87+91+x=98*4
264+x=392
x=392-264
x=128
The fourth number is 128
6.25t + 8 = 12.5t + 13
Subtract 8 from both sides
6.25t = 12.5t +5
Subtract 12.5t from both sides
-6.25t = 5
Divide -6.25 by both sides
t = 0.8
