<h2>a = 11 / 6</h2>
You want to find out what a is.
7a / 10 = 77 / 60
Put your equation into the form Ax = B, where x = a
You can multiply both sides by 10 to get rid of the denominator.
7a / 10 * 10 = 77 / 60 * 10
7a = 77 / 6
Put your equation into the form x = B, where x = a
You can get a on it's own by dividing both sides by 7.
7a ÷ 7 = 77 / 6 ÷ 7
a = 77 / 6 ÷ 7

a = 77 / 42
Simplify the fraction by dividing be a common factor - 7.
77 ÷ 7 = 11
42 ÷ 7 = 6

Answer: 20 cups of grape juice are needed for 8 cups of peach juice.
Step-by-step explanation:
5 times 4 is 20.
We must do this step because you need 2 cups for 1 batch, and times 4 that is 8. So then we multiplied 5 times 4.
So, 20 cups of grape juice are needed for 8 cups of peach juice.
Hope this answer helps you out!
Answer:
x = 7
Step-by-step explanation:
The triangles are similar
12/8 = (x+3+5)/(x+3) cross multiply expressions
12x + 36 = 8x + 64
12x - 8x = 64 - 36
4x = 28 divide both sides by 4
x = 7
(x-12)(x-1) is the answer.
15+m=34
-15. -15
M=19 N-12=-20 +12. +12
N=-8 V+16=8 -16. -16
V=-8 A-15=-5 +15. +15
A=10
