Answer:
We combine x ounces of 100% juice
with 40-x of 10% juice
to get 40 ounces of 55% juice
x + 0.1(40-x) = .55(40)
x + 4 - 0.1x = 22
0.9x + 4 = 22
.09x = 18
x = 20 ounces of 100% juice
40-x = 20 ounces of 10% juice
We combine 20 ounces of each.

Answer:
7 females, 24 males
Step-by-step explanation:
I solved it by using this equation:
2x + 17 = 31
then, i subtracted 17 on both sides:
2x=14
then divide by 2 on both sides:
x=7
then I added 7 to 17 to find the number of males:
7+17= 24
You divide 71 by 9 to get 7 8/9
Answer: x=3/2
Step-by-step explanation:
1st ring=$50
2nd ring=$37.50
3rd ring=$25
$50+$37.50+$25 =$112.50 total cost before tax
$112.50 X 1.08=$121.5 total cost and tax
3 X $50 X 1.08=$162 total cost without discount deal
$162 - $121.50 =$40.50 savings
