Average is just the total divided by the number of things you added up.
You've been given 4 numbers.
So just add 7.75+7.25+7.33+7.6 and then divide that by 4.
the answer is therefore 29.93/4
=7.4285
You can check if that seems right by just looking at the numbers, the average will be inbetween the smallest and largest numbers, so it matches up.

Answer:
x=13
Step-by-step explanation:
Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.
So, (5x-11) x (2x+20) x (11x-63) = 180.
Now, take away the parenthesis and add up all the like terms.
This should = 18x-54 = 180.
Now solve like you regularly would. Add 54 on both sides which equals,
18x=234. Now, divide 18 on both sides.
x = 13.
Hope this helps.
