So, this is a proportion problem. If we express 75% as a fraction (3/4ths), we have:

Since he won all of his games, we add the number won (x), to the number previously won and divide it by the total games played which is just the previous games played plus the number of current games played, so since he lost no games we still add x to the denominator as well. Solving this gives us:

That x value is 20.
You find a common denominator (the bottom one) and then add the numerator (the top) but you don't add the denominator, you just make it the same
(x+2)^2 over x+2
x^2+4 \x+2
x+2
Answer:
<u>Angle MON is equal to 130 degrees.</u>
Step-by-step explanation:
We are told LON is 180 degrees.
Angles LOM and MON are supplementary meaning they add to 180 degrees.
Using this information we know 12x+120=180.
We can use the subtractive property of equality to subtract 120 from both sides.
Do thins we get 12x=60.
Using the division property of equality we can divide both sides by 12 to get x=5.
We can then use the substitution property of equality to get MNO=8(5)+90.
<u>We can then simplify to get MNO=130.</u>
