Answer:
holy this is just substitution child
Step-by-step explanation:
1. y + 2, y = 4
if y is equal to 4, we can replace y in the equation
4 + 2 = 6
2. 6a / 3, a = 3
6 * 3 / 3 = 6
4. x - 7, x = 12
12 - 7 = 5
5. 2c - 4, c = 5
2 * 5 - 4 = 6
7. 2z - 3x
2 (8) - 3(5) =
16 - 15 = 1
8. 6x / (y + z)
(6 * 5) / (2 + 8)
30 / 10 = 3
4(w - 9) or 4w - 36
I hope I've helped you.
f^-1 (x) = - 6x-1 / 10 + 9x
18 centimeters
Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.
Divide the diameter by 2.
There you go, you found the circle's radius
