Awasher and a dryer cost $701 combined. the washer costs $51 more than the dryer. what is the cost of the dryer?

The dryer cost 325

Step-by-step explanation:

Let w = the cost of the washer

d = cost of the dryer

w+d = 701

w = d+51

Replace w in the first equation with d+51

d+51 +d = 701

Combine like terms

2d+51 = 701

Subtract 51 from each side

2d+51-51 = 701 -51

2d = 650

Divide by 2

2d/2 = 650/2

d = 325

The dryer cost 325

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
