Answer:
138.23 is the circumference
hope this helps
have a good day :)
Step-by-step explanation:
4x + 13y = 40
4x + 3y = -40
multiply second equation by -1
4x + 13y = 40
-4x - 3y = 40
add equations together
10y = 80
y = 8
put y in either original equation
4x + 3(8) = -40
4x + 24 = -40
subtract 24 from both sides
4x = 64
x=16
y=8
Answer:
m = 48
Step-by-step explanation:
6=m/8
Multiply each side by 8
6*8 = m/8 *8
48 = m
Answer:

Step-by-step explanation:

we substitute the value of "y" in the equation:
