Jason bought a soda that cost $4. he also bought 5 candy bars. he spent a total of $19. how much did each candy bar cost

A soda costs $4. He spent a total of $19. Subtract 4 from 19

19 - 4 = 15

He bought 5 candy bars. Divide 15 with 5

15/5 = 3

Each candy bar costed $3.

hope this helps

$3. $19 - $4 = $15 / 5 = $3! Hope this helps.

the correct answers i think are b. and d.

give me brainliest if it is correct!

(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
