X = 3*15 = 45
Hope it helped.
6:22, 9:33, are both equivalent to 3:11.
4.70, all the others can be simplified to 4.07 by taking away the zeroes after the 7 because they are not significant, The one before the 7 stays because it is significant as it is holding the tenths place value.
X=0, y=6
x=1, y=4
x=2, y=2
x=3, y=0
x=4, y=-2
Hope this helps :)
If b bisects in between FGE the answer is 84
