If a recipe requires 2 cups of flour for every 3 cups of sugar, then ___ cups of sugar are needed for 4 cups of flour.

6

Proportion:

  • Cups of flour (ratio 1) = 4 cups
  • Cups of sugar (ratio 2) = x cups

Since the recipe requires a constant ratio of flour to sugar (2:3), we can set up a proportion:

4 cups flour / x cups sugar = 2 cups flour / 3 cups sugar

Cross-multiply:

Multiply the left denominator (4 cups flour) by the right numerator (3 cups sugar):

4 cups flour * 3 cups sugar = x cups sugar * 2 cups flour

Simplify:

12 cups^2 sugar = 2x cups^2 flour

Solve for x (cups of sugar):

Divide both sides by 2 cups flour (the coefficient of x):

(12 cups^2 sugar) / 2 cups flour = (2x cups^2 flour) / 2 cups flour

Simplify:

6 cups sugar = x cups sugar

Answer:

x = 6 cups of sugar

47 = 2k+6 + 3k-9

K=10

Steps to solve:

1. Combine constant terms on the right side: 47=2k+6+3k−947=5k−3

2. Add 3 to both sides:47+3=5k−3+350=5k

3. Divide both sides by 5:550=55k

4. Simplify:k=10

Answer:k=10
