A washer and a dryer cost $790 combined. The washer costs $90 more than the dryer. What is the cost of the dryer?

The dryer would cost #350.

Step-by-step explanation:

With this kind of equation, you need to budget out steps.

Take away the $90 from the $790 so that the washer and dryer cost the same. You'll get $700. Divide $700 by 2 and you get $350.

Hope this helps! :)

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )
