Answer:

at least three are dimes

so we have 20 coins with a total of 3.50

if the rest are all quarters then there would be 4*3+2=14 but we need 20

so we are 6 short

we must have dimes in multiples of 5

12 q + 5 d=3.50 but only 17 coins

10q +10 dimes=3.50 with 20 coins

10 q +13 dimes total

algebraic solution

d+q=23

25q+10d=380

d=23-q

meriva

Answer:

70 minutes

Step-by-step explanation:

3 1/2 ÷1/4= 14 ×5= 70

so you first make 3 1/2 to an improper fraction, then you find the greatest common denominator between 7/2 and 1/4 which is 4, so you multiple 7/2 by 2 and get 14/4 and divide that by 1/4 and get 14minutes now multiply that by 5 laps and receive 70 minutes.
