Answer:
x= 6
Step-by-step explanation:
We can use the Pythagorean theorem to find x
x^2 + 2.5^2 = 6.5 ^2
x^2+ 6.25 =42.25
Subtract 6.25 from each side
x^2+ 6.25-6.25 =42.25-6.25
x^2 =36
Take the square root of each side
x = sqrt(36)
x= 6

Answer:
10 cars
Step-by-step explanation:
volleyball team = past money + money from car wash = 40 + 2 per car = 40 + 2 * number of cars
wrestling team = past money + money from car wash = 50 + 1 * number of cars
set the two equal to each other because they raise the same amount
40 + 2 * number of cars = 50 + 1 * number of cars
set number of cars to n
40 + 2n = 50 + n
subtract n from both sides to put all the variables on one side
40 + n = 50
subtract 40 from both sides to find n
n = 10
