Answer:

(5, - 5)

Step-by-step explanation:

Given the 2 equations

3x + 2y - 5 = 0 → (1)

x = y + 10 → (2)

Substitute x = y + 10 in (1)

3(y + 10) + 2y - 5 = 0 ← distribute and simplify left side

3y + 30 + 2y - 5 = 0

5y + 25 = 0 ( subtract 25 from both sides )

5y = - 25 ( divide both sides by 5 )

y = - 5

Substitute y = - 5 in (2) for corresponding value of x

x = - 5 + 10 = 5

Solution is (5, - 5)

There is 7/8 quarts of orange juice. Mrs. Mathewson would like to serve her guests 3/16 quarts orange juice. How many guests can
kotegsom [21]

Answer:

4\frac{2}{3} guests.

Step-by-step explanation:

We have been given that there are 7/8 quarts of orange juice. Mrs. Mathewson would like to serve her guests 3/16 quarts orange juice.

To find the number of guests Mrs. Mathewson can serve with 7/8 quarts of juice, we will divide 7/8 by 3/16 as:

\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{8}\div\frac{3}{16}

Convert to multiplication problem by flipping the 2nd fraction:

\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{8}\times\frac{16}{3}

\text{Number of guests Mrs. Mathewson can serve}=\frac{7}{1}\times\frac{2}{3}

\text{Number of guests Mrs. Mathewson can serve}=\frac{14}{3}

\text{Number of guests Mrs. Mathewson can serve}=4\frac{2}{3}

Therefore, Mrs. Mathewson can serve orange juice to 4\frac{2}{3} guests.
