Answer:
198
Step-by-step explanation:
If you take any 3-digit number and change the numbers around and subtract them you will always get 198.
They are not equivalent fractions. You will have to turn 3/4 into an 8th, so multiply it by two, (6/8) and plot that on a graph.
(2x+3)+(x-6)= 180 [straight angle]
2x+x+3-6=180
3x=183
x=61
