Answer:
There are 17 quarters and 15 half dollars.
Step-by-step explanation:
Let the number of half dollars be x,
number of quarters = x + 2
amount of half dollars = 0.5x
amount of quarters = 0.25(x + 2)
= 0.25x + 0.5
total amount = 0.5x + 0.25x + 0.5
= 0.75x + 0.5
0.75x + 0.5 = 11.75
0.75x = 11.25
x = 15
number of quarters = x + 2
= 15 + 2
= 17
There are 17 quarters and 15 half dollars.
On the y-axis segment GH starts at 2 and goes to 5. Therefore using 5-2 you get 3, the length of GH
There are an infinite number of 3 number sets that will equal 9000, unless your looking for whole numbers.
If you want to find a set of whole numbers, first break 9000 into its factors:
5 * 5 * 5 * 3 * 3 * 2 * 2 * 2 = 9000
Now to find a set of 3 numbers, just combine some of the factors.
For example:
(5 * 5 * 5) * (3 * 3) * (2 * 2 * 2) = 9000
125 * 9 * 8 = 9000
