Urgent needed : ( the original price of a sofa is $500. answer the following questions. a. if the sofa price decreased by 20%, what is the new price?

400

Step-by-step explanation:

If we start at 500 dollars and we have the priced decreased by 20%, then we are paying 80% of that 500 dollars since 80%+20%=100% which is the whole price.

So we need to calculate .8(500) which is 400.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x
