Josh rented a truck for one day. there was a base fee of 20.99 and there was a additional charge of 86 cents for each mile driven josh had to pay 133.65 when he returned the truck for how many miles did he drive the truck ?

The drove the truck for 131 miles

Step-by-step explanation:

To get the number of miles travelled

Step 1: Subtract base fee from payment

133.65 - 20.99 = $112.66

If each mile costs 86 cents = $0.86

Step 2: Divide $112.66 by $0.86

112.66/0.86 = 131 miles

7

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
