Answer:
9 cups
Step-by-step explanation:
We can use ratios to solve
1/3 cup red 4 cups red
----------------- = -------------------
3/4 cup yellow x cups yellow
Using cross products
1/3 *x = 3/4 *4
1/3x = 3
Multiply each side by 3
1/3 x * 3 = 3 * 3
x = 9
Answer:
8
Step-by-step explanation:
6g = 48
/6 /6
divide 6 by both sides
g = 8
hope this helped!
1) Move the non-x term to the right
x^2 +6x = -c
2) Divide the equation by the coefficient of x^2
(You don't have to because it is one).
3) Get the "x" coefficient, divide it by 2, square it then add it to both sides:
6 divided by 2 = 3
3^2 = 9
x^2 +6x +9 = -c +9
Take the square root of both sides
(x +3) = sq root (9 -c)
x = -3 + sq root (9 -c)
