You are shopping for t-shirts. which store offers the better deal? belk : $25 for 2 shirts old navy : $45 for 4 shirts target : $30 for 3 shirts gap : $55 for 6 shirts

well, let's see

Belk

$25 for 2 shirts, that means 1 shirt is 25 ÷ 2, or $12.5.

Old Navy

$45 for 4 shirts, that means 1 shirt is 45 ÷ 4, or $11.25.

Target

$30 for 3 shirts, that means 30 ÷ 3 for 1 so, 10 bucks each.

Gap

$55 for 6 shirts, meaning 55 ÷ 6 for 1, or about $9.17.

which one is the cheapest? yeap, you're correct.

its a trick question

step-by-step explanation:

dogs love water, just turn on the hose and it will run in circles chasing the water all day : )

(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
