10 adults + 5 children = $75 ------------- (1)
8 adults + 10 children = $78 ------------- (2)
(1) x 2 : 20 adults + 10 children = $150 ------------- (1a)
(1a) - (2) : 12 adults = $72
1 adult = $6
Substitute 1 adult = $6 into (1):
10 ($6) + 5 children = $75
$60 + 5 children = $75
5 children = $15
1 child = $3
Therefore 1 adult = $6 and 1 child = $3
Find 6 adult and 10 children:
6 adults + 10 children = 6(6) + 10(3) = 36 + 30 = $66

The radius is 1/2 the diameter so 17 inches. In one turn you will go about 44 inches. The circumference.
Answer:
9.74 feet
Step-by-step explanation:
the formula for finding a hypotenuse is 
. We can rearrange that to get: 
. So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.
Your Answer Is C) III Only.
A temperature increase of 5/9 degrees Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.
One way we could check is by multiplying (f -32) by five degrees.
( f - 32 ) = 31
9 / 5 = 1.8
31 * 1.8 = 55.8
55.8 / 14^2 = 0.28
Now, let's check,
0.28 / 1.8 = 0.504
0.504 * 28.1232 = 55.8
Or it could be solved by keeping on adding. (That would be easier but I prefer multiplying.)
