Answer:
10 cups
Step-by-step explanation:
we can set up a proportion of cups of water over cups of apple juice
2/3 = w/15
if you cross-multiply you will get:
3w = 30
w = 30/3
w = 10
Answer:
y = -6/5
Step-by-step explanation:
Remove parentheses
2y - 2 - 7y = 4
group like terms
2y - 7y - 2 = 4
add similar elements
-5y - 2 = 4
add 2 to both sides
-5y - 2 + 2 = 4 + 2
simplify
-5y = 6
divide both sides by -5
-5y ÷ -5 and 6 ÷ -5
simplify
y = -6/5
Answer: 7/3
Step-by-step explanation:
21/9
7/3 is the fraction in simplest form
Answer:
in regards to ratios, think of fractions. If we have a ratio of 3:5, that means that in fraction form we can think of it as
3
---
5
If put this into a calculator (3 divided by 5), you will get a decimal of 0.6 as the answer. This means that any two numbers that divide and come to the same answer are equivalent to 3/5.
Now, from what it appears you are asking, they want you to find two other numbers that come to the same ratio / answer of 0.6, and that these numbers should be double. To do this, simply multiply the numerator and denominator by 2, which is double.
3 x 2 = 6
5 x 2 = 10
So our fraction now is
6
---
10
If you put that into a calculator (6 divided by 10), it will come to the same answer of 0.6. Therefore, this fraction / ratio is equivalent to the original.
If your answer is expected to be in ratio format, then it should be 6:10

Answer:
Anna's number could be 5 and it could be 6.
Step-by-step explanation:
Let Anna's number be represented by x.
If Bill squared her number followed by subtracting 11 times her number, and adding 4, then he would get -26.
This implies that:
This is a quadratic equation and we can solve for x by factorization.
=> x = 5 and x = 6
Anna's number could be 5 and it could be 6.
