You are in charge of drinks for a community barbecue. You need to supply at least 120 cups of beverage to provide enough for the

olga nikolaevna [1]

Answer:

You have 112 cups of beverage

Step-by-step explanation:

* Lets explain how to solve the problem

- You need to supply at least 120 cups of beverage to provide enough

for the projected number of people that will attend

- Assume that a cup can fill by 8 fl. oz. (American standard)

- You have received the following donations

- Enough mix to make 4 gallons of lemonade

∴ You have 4 gallons of lemonade

∵ 1 gallon = 128 oz.

∴ 8 gallons = 4 × 128 = 512 oz.

∴ You have 512 oz. of lemonade

∵ You can fill one cup by 8 oz.

∴ The number of cups of lemonade = 512 ÷ 8 = 64 cups

- 6 bottles of fruit juice that each contain 64 fl. oz

∵ 6 × 64 = 384

∴ You have 384 oz. of fruit juice

∵ You can fill one cup by 8 oz.

∴ The number of cups of fruit juice = 384 ÷ 8 = 48 cups

- Now add the number of lemonade cups to the number of fruit

juice cups

∵ There are 64 of lemonade cups

∵ There are 48 fruit juice cups

∴ The total number of cups = 64 + 48 = 112 cups

* You have 112 cups of beverage

5x - 7x + 6 = -2 (x - 3) Or... Are there no solutions or infinite solutions

MissTica

Answer:

there are no solutions

Step-by-step explanation:

5x−7x+6=−2(x−3)

Step 1: Simplify both sides of the equation.

5x−7x+6=−2(x−3)

5x+−7x+6=(−2)(x)+(−2)(−3)(Distribute)

5x+−7x+6=−2x+6

(5x+−7x)+(6)=−2x+6(Combine Like Terms)

−2x+6=−2x+6

Step 2: Add 2x to both sides.

−2x+6+2x=−2x+6+2x

6=6.

Step 3: Subtract 6 from both sides.

6−6=6−6

0=0

Lois made a dish with 4 1/3 of pasta. One serving of the pasta is 0.2 cups. How many servings of pasta were in the dish Lois mad

Kipish [7]

Answer:

21.67.

Step-by-step explanation:

Here is the correct question: Lois made a dish with 4 1/3 cups of pasta. One serving of the pasta is 0.2 cups. How many servings of pasta were in the dish Lois made?

Given: Lois made dish with $4\frac{1}{3}$

One serving of pasta= 0.2 cups

Now, using unitary method to find total number of servings of pasta were in the dish Lois made.

First, lets convert $4 \frac{1}{3}$ into decimal

$\frac{4\times 3 +1}{3} = \frac{13}{3}$ = 4.33 cups

∴ Lois made a dish with 4.33 cups of pasta.

We know, One serving of pasta= 0.2 cups

∴ Total serving in 4.33 cups of pasta= $\frac{4.33}{0.2}= 21.6666 \approx 21.67$

∴ 21.67 serving is possible in $4\frac{1}{3} \ cups$ of pasta.
