Answer:
r = 2.5
Step-by-step explanation:
the area of the whole circle = 
*π * 24
A = πr² = (13π*24)/50
r = √((13*24)/50) = 2.5 inches
You can make a ratio of red to overall colors and then that will give you the fraction, you might have to simplify it
Answer:
73
Step-by-step explanation:
Original number: XY
x = 3y - 2
10y + x = (10x + y) / 2 + 1/2
substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2
* 2 both sides and simplify: 26y - 4 = 31y - 19
31y - 26y = -4 + 19
5y = 15
y = 3
x = 7
Original number: 73
