Please help!!! JT subscribes to a cell phone texting plan with three other members of his family. Within any given month, they can send at most 500 texts. At the end
of this month, JT had sent 25 more texts than his older sister, 50 fewer texts
than his younger sister, and 125 more texts than his mother. How many texts
could JT hậve sent if they did not go over the 500 text limit? Write a multi-step
inequality and solve. Then write your answer in interval notation.

b. astronomers

(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
