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

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:

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

9x = 64 + 8

x=72/9

x=8

9x -8

How do I solve for x? -3x+7=1

inna [77]

Answer:

x=2

Step-by-step explanation:

-3x+7=1

subtract 7 from both sides: -3x+7-7=1-7

simplify: -3x=-6

divide both sides by -3: $\frac{-3x}{-3}=\frac{-6}{-3}$

simplify: x=2
