Answer:
d.
Step-by-step explanation:
Since it's an isosceles triangle, WX=WZ= 2n-5
Perimeter = n + (2n-5) + (2n-5)
= 5n - 10
The Perimeter is given to be 20
5n - 10 = 20
5n = 30
n = 6
The probability that the card is a football card is 20 out of 50 or 40%
the probability that the card is a basketball card is 10 out of 50 or 20%
She would need approximately 16 yards
servings = 6
molds = 113
