448 = -5v + 8(-5 - 7v)<br> What is v?
lapo4ka [179]

Answer:

v = -8

Step-by-step explanation:

First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get 448=-5v-40-56v. After this, we would have to simplify like terms by subtracting 56v from -5v to get 448=-61v-40. We now have to get the variable on one side and to do that, we can add 40 to both sides to get 488=-61v. Finally to get the variable alone, we would have to divide both sides by -61 to get v=-8.

Brainliest would be appreciated!

On a Saturday the ratio of the amount of water used by Household A to the amount of water used by Household B was 13:5.Household
Reptile [31]
Use a proportion.

Let A = water used in household A.
Let B = water used in household B.

A to B = 13 to 5

A = 260 gal

260 to B = 13 to 5

260/B = 13/5

13B = 5 * 260

B = 100

A + B = 260 + 100 = 360

The total is 360 gallons.
