The food bank has 1774.4 oz of chicken.If 12.6 oz is 2 servings,how many servings of chicken does this provide?
diamong [38]

Answer:

281 servings

Step-by-step explanation:

From the table attached,

We will apply the unitary method to solve this problem.

∵ 12.6 oz of chicken represents number of servings = 2

∴ 1 oz of chicken will represents number of servings = \frac{2}{12.6}

∴ 1774.4 oz of chicken will make the total servings = \frac{2}{12.6}\times 1774.4

                                                                                    = 281.65

                                                                                    ≈ 281 servings

Therefore, total number of servings provided = 281

Write as an algebraic expression
Mazyrski [523]

Answer:

13) x=n-11

15) x=3*10

Step-by-step explanation:

I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!
