Answer:
C = 
Step-by-step explanation:
given A varies directly as B and inversely as C then the equation relating them is
A = 
← k is the constant of variation
to find k use the condition A = 6 , B = 10 , C = 15 , then
6 = 
( multiply both sides by 15 )
90 = 10k ( divide both sides by 10 )
9 = k
A = 
← equation of variation
when A = 92 and B = 107 , then
92 = 
( multiply both sides by C )
92C = 963 ( divide both sides by 92 )
C =
A. 108 degrees
b. 72 degrees
c. 108 degrees

<span>A number, half of that number, and one-third of that number are added.
This statement can be expressed as:
x + (1/2)x + (1/3)x
The total is 22
</span>x + (1/2)x + (1/3)x = 22
So let's look for x
x + (1/2)x + <span>(1/3)x = 22
</span>(6x + 3x + 2x) / 6 = 22
11x = 132
x = 12
So the original number is 12.
They are all correct good job
