Answer:
13
Step-by-step explanation:
Since we want to find f(x) when x equals 10, we can substitute 10 in for x
f(x)=x/2 +8
f(10)=10/2+8
Divide 10 by 2
f(10)=5+8
Add 5 and 8
f(10)=13
So, f(x) when x=10 is 13
Answer:12, 84 and 84
Step-by-step explanation:
since we know 3 angles of a triangle = 180 degrees
1 angle = 12 degrees
12 + x + x = 180
12 + 2x = 180
2x= 180 - 12
2x = 168
x = 168/2
x = 84 degrees

Answer:
-7
Step-by-step explanation:
k(x) = x/5 - 3
k(-20) = -20/5 -3
k(-20) = -4 - 3
k(-20) = -7
So you first do 26 x 14 = 364 miles for 14 gallons
838 ÷ 364 = 2.302
You then have to round the number, and because you can't stop 0.302 times, the answer is 3.

Answer:
C) 4
Step-by-step explanation:
Replace the variable a with 4 to see if it makes the equation true.
4 + (-7) + 3 = -3 +3
-3 + 3 = 0; thererfore, the number 4 is the proper solution to the equation.
