Answer:
7
Step-by-step explanation:
To find the number, first multiply 8 by 3, since that is how you find the mean.
8 x 3 = 24 (total)
x + 6 + 11 = 24
x = 24 - 6 - 11
x = 7
Inverse:
7 + 6 + 11 = 24
Mean = 24/3 = 8

Tamika ran the fastest time at 21.6 seconds in 120 meters because the faster you run the less time you have on your timer.
300-3x=33
Subtract 300 on both sides.
-3x=-273
Divide both sides by -3.
x=91
