It would be great if you added some more details, but for common denominators you try to find the least common number that the 2 or more of the numbers you got have!
For example:
1/2 and 2/3 if you multiply 2 by 3 and 3 by 2, they both are 6, so you would multiply 1/2 both by 3 to make it into 3/6 and 2/3 by 2 to make it into 4/6!
Answer:
$38.06
Explanation:
Multiply $31.20 by 0.22 (22%)
Which equals 6.864
Add that to $31.20 and you get 38.064
Then you round it and get $38.06
The answer is C because its the only touching the circle on each end
Yep they do, because if you plug in y for both equations, you get x=0. To find y, plug in 0 for either equation to get -7. (0,-7) should work for both equations since the intersection point is the point where both equations meet.
