Taking a shower accounts for about 20 of your daily water usage You use 60 gallons of water daily for other purposes How many gallons of water do you use daily class=

Respuesta :

60 x 0.2 divided by 1 - 0.2
12/1 - 0.2
12/0.8
Rewrite the fraction
120/8
Simply into 15

The number of gallons of water you use daily while taking a shower is 12 gallons and the value of m in equation 8m + 5 = 6m + 1 is 2.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

As we know, the percentage is the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

For the percentage problem:

A number of gallons of water you use daily while taking a shower:

= 20% of 60

= (20/100)60

= 12 gallons

For the linear equations:

We have:

8m + 5 = 6m + 1

8m - 6m = 1 - 5

-2m = -4

m = 2

Similarly, we can solve any linear equation.

Thus, the number of gallons of water you use daily while taking a shower is 12 gallons and the value of m in equation 8m + 5 = 6m + 1 is 2.
