8 is the answer to your question
Answer:
August made the recipe using the correct ratios
Step-by-step explanation:
we know that
Sally uses 6 cups of lemonade for every 8 cups of fruit punch
so
using proportion
Find out the number of cups of fruit punch for 15 cups of lemonade
Let
x ----> the cups of fruit punch
The total cups of liquid is the sum of the cups of lemonade plus the cups of fruit punch
so
therefore
August made the recipe using the correct ratios
Answer:
Western U gets 20 million
Norther U gets 40 million
Eastern U gets 50 million
Step-by-step explanation:
We need to find the amount each university gets.
Let
Northern U get n
Western U get w
Eastern U get e
We can write equations from the given word problem:
n + w + e = 110
and
n = 2w
e = n + w - 10
Putting 2nd in 3rd, we get:
e = 2w + w - 10
e = 3w - 10
Now putting this and 2nd in first, we solve for w:
n + w + e = 110
2w + w + 3w - 10 = 110
6w = 120
w = 20
AND n = 2 (20) = 40
AND e = 3(20) - 10 = 50
So,
Western U gets 20 million
Norther U gets 40 million
Eastern U gets 50 million
Answer:
40
Step-by-step explanation:
10=25% so multiply 10 by 4 and cause there is 4 25% in 100
Answer:
4, 22 See below
Step-by-step explanation:
2x + y = 30
5x + y = 42
Subtract the first from the second
3x = 12
x = 4 so socks cost $4
Put that into one of the original equations
2x + y = 30
2(4) + y = 30
8 + y = 30
y = 22 slippers cost $22
