that is the answer by the way
Answer:
~1.29 inches
Step-by-step explanation:
C = 2πr
C = 3r + 4.25
2πr = 3r + 4.25
2πr - 3r = 4.25
r(2π-3) = 4.25
r = 4.25/(2π-3) ≈ 1.29
Step-by-step explanation:
First, distribute the outside numbers into the parentheses:
5*x+5*-12+6=3*2x+3*-7
5x-60+6=6x-21
Combine like terms
5x-54=6x-21
Add 21 to both sides
5x-33=6x
Subtract 5x from both sides
you wind up getting x=-33
x=-33
you can check to make sure that's the correct answer but simply plugging in -33 for x and checking to make sure both sides of the equation are equal:
-33-12=-45*5=-225+6=-219
-33*2=-66-7=-73*3=-219
So, yes, x equals -33
