Answer:

3x = -2 2/5 or -2.4

5x + 8 = 4

5x = 4 - 8

5x = -4

x = -4/5

3x = y  If x = -4/5

3 * -4/5 = y

-12/5 = y

-2 2/5 = y

denis-greek [22]

Answer:

She will need 3.5 pounds of cheese to make the 28 casseroles

Step-by-step explanation:

In this question, we are tasked with calculating the amount of cheese in pounds needed to make 28 casseroles.

In the revised recipe, she intends using 1/2 of what is supposed to be used in the original recipe. Mathematically, since each original casseroles is meant to take 4 ounces of cheese, the revised recipe taking half will have 1/2 × 4 = 2 ounces of cheese per casserole

Now for 28 casseroles based on the revised recipe, the total amount of cheese to be used mathematically is equal to 28 × 2 = 56 ounces of casserole

The questions asks that our answer be in pounds

Mathematically, 1 ounce = 0.0625 pounds

Hence, 56 ounces of casseroles will be 56 × 0.0625 = 3.5 pounds of cheese
