She'll need 30 lemons for 10 cups of water. Just multiply 3 by 10, or you can add 3 to every cup of water.
My answer is short, but hopefully I helped.
Answer:
1:2
Step-by-step explanation:
18 inches to 1 yard
We need to convert 1 yard to 36 inches
18 inches : 36 inches
Divide each side by 18
18/18 : 36/18
1:2
X + y = 22
x = 3y + 2
3y + 2 + y = 22
4y + 2 = 22
4y = 22 - 2
4y = 20
y = 20/4
y = 5
x = 3y + 2 = 3(5) + 2 = 15 + 2 = 17
ur numbers are 5 and 17
You use the equation Ax^2 + Bx + C to solve this equation.
The answer is 25.
I hope this helps :D
