People use water to​ cook, clean, and drink every day. An estimate of ​15.2% of the water used each day is for drinking . If a family uses 68.4 gallons of water a day for ​, how many gallons do they use every​ day?

83.6

Step-by-step explanation:

add 15.2 with 68.4

the answer to the equation is therefore 83.6 and don't blame me if I got the wrong answer bc I'm just using this to get a good grade in science and English mostly

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
