raketka [301]

Answer:

B) (3,1)

Step-by-step explanation:

y = -2x + 7

y = 3x - 8

3x - 8 = -2x + 7

combine like terms:

5x = 15

divide both sides of the equation by 5:

x = 3

y = 3(3) - 8 = 1

How many quart are 8/1/4 gallons

Westkost [7]

Given:

Consider the given gallons are $8\dfrac{1}{4}$ gallons.

To find:

The number of quarts in $8\dfrac{1}{4}$ gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

$8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}$

$8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}$

$8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}$

$8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}$

Therefore, there are 33 quarts in $8\dfrac{1}{4}$ gallons.
