Since the question is asking for the no. of coins each, we can represent the numbers with variables.
number of quarters = x
number of dimes = 6x (because there as 6 times as many dimes as quarters)
Next we can multiply the variables by the value of each coin.
25x + 6(10)x = 1275
25x + 60x = 1275
(make sure the expressione quals 1275, not 12.75. A dime is not 10 dollars, nor is a quarter 25 dollars).
85x = 1275
x = 15
Now that we have the value for x, plug it back in.
Andrea has 15 quarters and 90 dimes.

Answer:
Two semi circles would equal one circle.
The perimeter of a circle is PI x diameter.
The diameter of the circle is shown as 56 m
The perimeter of the 2 ends = 56 x 3.14 = 175.84
The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.
Total perimeter = 260 + 175.84 = 435.84 m.
Step-by-step explanation:
6.20 x .15 = .93
6.20-.93= 5.27
107.27-5.27=102
102 x .15 = 15.3
102+15.3=117.3
$117.3
