In a 24 polygon, 23 of the exterior angles add to 310 degrees. What is the measure of the 24th exterior angle?

1 answer:

8 0

The sum of the exterior angles of a polygon sum to 360. Since the first 23 exterior angles give you 310 you have one angle left and 50 degrees left. Therefore the 24th exterior angle must be 50degrees.

Abdul's gas tank is 1/5 full. After he buys 7 gallons of gas, it is 7/10 full. How many gallons can Abdul's tank hold?

eduard

Answer: 14 gallons

Step-by-step explanation:

Let's call the total gallons of gas Abdul's tank can hold <em>x</em>.

Then, based on the information given in the problem, you can write the following expression:

$\frac{1}{5}x+7=\frac{7}{10}x$

Therefore, when you solve for x, you obtain the following result:

$\frac{1}{5}x+7=\frac{7}{10}x\\\\\frac{1}{5}x-\frac{7}{10}x=-7\\\\-\frac{1}{2}x=-7\\\\-x=(-7)(2)\\x=14$
