Answer:

2 quarters

4 nickels

9 dimes

Step-by-step explanation:

quarters = x

nickels = 2x

dimes = 2x+5

25x+5(2x)+10(2x+5)=160

25x+10x+20x+50=160

55x=160-50

55x=110

x=2

SO:

(x) = 2 quarters

(2x) = 4 nickels

(2x+5) = 9 dimes

postnew [5]

Answer:

15N + 21

Step-by-step explanation:

We are given that,

Amount of carpet bought by Peter = N meter²

The cost per meter square of the carpet = $15

So, the cost of 'N' meter square of carpet = 15N dollars.

Also, the delivery charge for the carpet = $21

Thus, the total cost of the carpet is given by,

Total cost = Cost per square meter + Delivery charge

i.e. Total cost = 15N + 21 (in dollars).

Hence, the expression representing the cost in dollars is '15N + 21'.
