In this question use 1 cubic foot = 6.23 gallons
1 cubic foot = 0.028 cubic metres
Convert 3738 gallons into cubic metres.

16.8 cubic metres

Step-by-step explanation:

Given: 1 cubic foot = 6.23 gallons

           1 cubic foot = 0.028 cubic metres

Let the conversion into cubic metres be represented by x.

Thus we can say that;

6.23 gallons = 0.028 cubic metres

and

3738 gallons = x cubic metres

So that,

x =

   = 16.8

x = 16.8 cubic metres

The conversion of 3738 gallons into cubic metres is 16.8 cubic metres.

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. : )
