(88 + 94 + 89 + 85 + x) / 5 = 90
(356 + x) / 5 = 90
356 + x = 90 * 5
356 + x = 450
x = 450 - 356
x = 94 <==
-6k-6 = -8k+22
-6k+8k = 22+6
2k = 28
K= 28/2
K= 14
Answer:
38 cm
Step-by-step explanation:
Answer:
the answer is going to be supplementary angles
9*3.14 = 28.26
(This solves for circumference)
300/28.26 = 10.6157
(This solves for rotations)
About 11 rotations.
