Answer:
13.68
Step-by-step explanation:
72 * 0.19 = 13.68
19% can be converted to 19/100 or .19 to change out of a percentage. .19 is the multiplied by 72 to find 19% of 72.
For example
a fourth of something is the same as 25%.
if you want to find 1/4 of 8 you would multiply 8 by 1/4.
It is a similar concept with percentages.

So, Our final answer is 145%
To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is 5x.
Since 10 is being added to 5x, we subtract 10 from both sides of the equation to isolate the 5x.
On the left, the +10 and -10 cancel out and on the right, 20 - 10 is 10 and we have 5x = 10.
Now we can finish things off by just dividing both sides of the equation by 5. On the left the 5's cancel and on the right, 10 divided by 5 is 2 so <em>x = 2</em>.
