A washer and dryer cost $803 combind the washer costs $47 less then the dryer whats is the cost of the dryer

the dryer costs $425

Step-by-step explanation:

x = washer

y = dryer

x + y = 803

x = y - 47

using the second equation a substitute in the first equation we get

y - 47 + y = 803

2y = 850

y = $425

FYI

x = y - 47 = 425 - 47 = $378

The dryer costs $425

Step-by-step explanation:

803 - 47 = 756

756 / 2 = 378 (price of the washer)

378 + 47 = 425 (price of the dryer)

B = x

A = 2x - 5

C = x + 5

The perimeter P = A + B + C and P = 160 cm

Substitute

(2x - 5) + x + (x + 5) = 160

(2x + x + x) + (-5 + 5) = 160

4x = 160 |:4

x = 40 cm

A = 2x - 5 → A = 2(40) - 5 = 75 cm

B = x → B = 40 cm

C = x + 5 → C = 40 + 5 = 45 cm
