Well, let's check if your inequality is true. We have to add the 3 scores up and divide them by 3 to know the average.
73 + 81 + 86 = 240
240 / 3 = 80
80%
That's true, now let's check 101.
73 + 81 + 101 = 255
255 / 3 = 85
85%
That's true.
Your inequality is correct.
9x + 4 = 58
9x = 54
x = 6
The number is 6.
