To find this answer, we need to multiply 3.57 by 12.
Therefore, 12 planks will cost $42.84.
From the little marks on the sides, we can see that YZ is the midpoint segment.
YZ is half of VX
12.2 is the answer.
So you know the whole line is XZ which is 83.Then you find out it is in two parts so that is XY and YZ which are 11 and 4c. You can make the equation:
11+4c=83
4c=72
c=18
c=18 and YZ=72
Are A and B supplementary or complementary
