Arealtor earns a 3.25% commission
on the sale of each house. how much
did a house sell for if the realtor earned
$10,566.40?

Since the commission is 3.25%, we simply multiply this fraction in decimal form by x, since it will equal 10566.40:

0.0325*x=10566.40

Divide both sides by 0.0325:

x = 10566.40/0.0325

x = 325120

The house sold for $325,120

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
