Answer:

-27=x

Step-by-step explanation:

Move the 3 over and subtract the 3x from the 4x so that the equation looks like 1x+27=0. Then subtract the 27 to the other side so that the equation is 1x=-27. Divide both sides by 1 and you get x= -27.

A salesman priced a four wheeler at $3,500 the first day it was on the market. The second day he reduced the price by 10%. What
Karo-lina-s [1.5K]

Answer:


$3,150

Step-by-step explanation:

To find the sale price, multiply the original price ($3,500) by 0.90.  This 0.90 comes from subtracting 10% from 100% and converting the result to the decimal fraction 0.90.

0.90($3,500) = $3,150
