There are 31 coins of dimes and quarters. If the number of dimes is 5 more than the number of quarters, how many quarters are th

emmasim [6.3K]

Answer:

13 Quarters and 18 Dimes

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Give x and y a break, and make it easier to remember which is which.

D + Q = 31

D = Q + 5

Therefore:

D + Q = 31

(Q+5) + Q = 31

2Q + 5 = 31

2Q = 26

Q = 13

Then D = (13+5) or 18

================

Check:

D + Q = 31 ?

18 + 13 = 31 YES

----------------------

D = Q + 5 ?

18 = 13 + 5 YES

Riley rakes 1/6 of a lawn in 2/3 hour. How many lawns can Riley rake per hour?

Butoxors [25]

Answer:

Riley rakes 1/4 of the lawns per hour.

Step-by-step explanation:

It is given that,

Riley rakes 1/6 of a lawn in 2/3 hour.

We need to find how many lawns can Riley rake per hour.

In 2/3 hour Riley rakes 1/6 of a lawn

In 1 hour Riley rakes $\dfrac{1}{6}\times \dfrac{3}{2}=0.25$ = 1/4 of a lawn.

Hence, Riley rakes 1/4 of the lawns per hour.
