10 + 8c= 42
subtract 10 from both sides
8c= 32
divide both sides by 8
c= 4
CHECK
10 + 8(4)= 42
10 + 32= 42
42= 42
ANSWER: c= 4

Answer:
360
Step-by-step explanation:
The formula is (n-2)180 -> 6(180) = 1080
1080/8=135
135 is the measure of one interior angle so the exterior has to equal 45 for one side.
45 x 8=360
The answer is 360
1/6-1/10=.66_ if that makes sense.
Answer:
270
Step-by-step explanation:
The mean is 228 and the standard deviation is 18.
2.3 standard deviations above the mean is:
228 + 2.3×18
228 + 41.4
269.4
Since scores are usually integers, we round up to 270.
