3x - 13 = 8

Add 13 to both sides.

3x = 21

Divide both sides by 3.

x = 7

Now that we have the value of x we can solve x - 4.

7 - 4 = 3

The value of x is 7, and the answer to the second expression is 3.

Answer:

22.73% of ounces Isabella has left of her cola.

Step-by-step explanation:

Given:

Isabella has a 22 ounce cola. She drinks 17 ounces.

Now, to find the percentage of ounces Isabella has left of her cola.

Total ounces of cola = 22.

Ounces of cola Isabella drink = 17.

So, the ounces of cola she left:

Total ounces of cola - ounces of cola Isabella drink.

$=22-17$

$=5\ ounces.$

Thus, 5 ounces of cola she left.

Now, to get the percentage of cola she left:

$\frac{5}{22}\times 100$

$=\frac{500}{22}$

$=22.727\%.$

Rounding the percentage to the nearest hundredths is 22.73%.

Therefore, 22.73% of ounces Isabella has left of her cola.
