Answer:

x = 18

Step-by-step explanation:

x - (-9) = 27

Notice that there is negative sign before (-9).

If you do, turn the value into positive.

Tip:

- × - = +

+ × + = +

- × + = -

+ × - = -

Now going back,

x + 9 = 27

Subtract by 9 on both sides:

x + 9 - 9 = 27 - 9

x = 18

Schach [20]

Answer:

28%

Step-by-step explanation:

We get 30% off the original price

The new price is (100-30) = 70$ of the original price

Let x = the original price

The new price is .7x

Now get get an additional 60% off. We pay (100-60) = 40 percent of the price

Take .7x * .4

The new price is .7*.4 x

.28x

This is 28 percent of the original price x
