Number of cards = 48
Number of red cards = 48/2 - 8 = 24 - 8 = 16
Number of black cards = 48/2 = 24
Ratio of red cards to black cards = 16:24 = 2:3
Answer:
D 8 pizzas
Step-by-step explanation:
Answer: x/y=1
a(x-y)=b(y-x)
(a+b)x=(a+b)y
x/y=1 ans

72
l = 5w
A = l*w
180 = 5w *w
180 = 5w^2
Divide each side by 5
180/5 = 5w^2 /5
36 = w^2
Taking the square root of each side
sqrt(36) = sqrt(w)^2
6 =w
l = 5w = 5*6 = 30
The perimeter is
P = 2(l+w)
P = 2(6+30) = 2(36) = 72
