A washer and dryer cost $697 combined. The washer costs $53 less then the dryer. what is the cost of the dryer ?

The dryer costs $375

Step-by-step explanation:

First, let's declare variables and set up equations:

let x be the washer

let y be the dryer

x + y = 697

x = y - 53

lets substitute the second equation into the first one:

x + y = 697

( y - 53 ) + y = 697

Combine like terms:

( y + y ) - 53 = 697

2y - 53 = 697

Add 53 to each side:

2y = 750

Divide each side by 2:

y = 375

Since we are only finding the price of the dryer, which is y, we do not need to go on.

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
