1/3x=20

1st step do the opposite of 1/3x to get it by itself. So you would do 1/3x *3/1 than you would do 3/1 *20. What you do to that side you do to the other.

2nd step 20*3=60

3rd You can check your answer by doing 1/3 *60=20

I plugged the answer in the variable to Check it

4) Crystal wants to buy the newest iPhone XS Max that costs $1200.

Answer:

8.75%

Step-by-step explanation:

If she pays $135 eight times then she pays a total of 135 x 8 = $1080.

She had a down payment of $225, so that added on becomes $1305.

1305/1200 is 1.0875, which is an increase of 0.0875 over the original.

0.0875 x 100 = 8.75% increase.

First we distribute $\frac{1}{5}$ into $n$ and $-\frac{1}{7}$ .

$\frac{1}{5} * n = \frac{1}{5} n$
$\frac{1}{5} * -\frac{1}{7} = - \frac{1}{35}$

That makes the left side of the equation

$\frac{1}{5} n - \frac{1}{35} = \frac{1}{6} n$

Now we subtract $\frac{1}{5}n$ from $\frac{1}{6} n$ , which makes $\frac{1}{30}$

Now the equation is

$-\frac{1}{35} = -\frac{1}{30n}$

Our goal is to isolate $n$ , so we both sides by 30

$30* -\frac{1}{35} = - \frac{1}{30}n * 30$

That will make the equation

$- \frac{30}{35} = -n$

We multiply -1 on both sides of the equation:

$\frac{30}{35} = n$

Finally we simplify $\frac{30}{35}$ , which makes $\frac{6}{7}$

So the answer is $n = \frac{6}{7}$
