Answer:

{12, 16}

Step-by-step explanation:

The difference of two <em>numbers (x and y)</em> is 4.  Thus, if y is the larger, then y - x = 4.  Also, y = 2x - 8.

So we need to solve the system of linear equations

y - x = 4

y = 2x - 8

Subbing 2x - 8 for y, in the first equation, we get  (2x - 8) - x = 4, or

x - 8 = 4, and conclude that x = 12.  Then, because y - x = 4, y must be 16.

The numbers are 12 and 16.

You usually buy a 16.5-ounce bottle of shampoo. There is a new bottle that says it gives you 30% more free.
Katarina [22]

Answer:

\frac{x-16.5}{16.5}=0.30

Hopefully, this is your desired setup. (I noticed the formula you have to fill in there.)

Have a good day.

Step-by-step explanation:

Hi.

You could use the percent change formula.

Since we know it is a percent increase then we will do new-old instead of old-new:

\frac{\text{new}-\text{old}}{\old}

x is the new amount of shampoo.

16.5 is the original amount (old) of shampoo.

The percent increase is 30%=0.30 .

So we have the following equation:

\frac{x-16.5}{16.5}=0.30

We could have found the equation like this:

16.5+16.5(0.30)=x

Subtract 16.5 on both sides:

16.5(0.30)=x-16.5

Divide both sides by 16.5:

0.30=\frac{x-16.5}{16.5}

By us of symmetric property of equality:

\frac{x-16.5}{16.5}=0.30
