Answer: There was 5/8 of a foot of board left.
Step-by-step explanation:
Step 1. We need to subtract 1/4 from 7/8. To do this make it where both fractions have the same denominator.
Step 2. The easiest way to do this is to multiply 1/4 by 2.
1/4*2/2=2/8.
Step 3. Now all you got to do is subtract 2/8 from 7/8.
7/8-2/8= 5/8.
Answer:
The second option
Step-by-step explanation:
The rate of change needs to stay constant.
The rate of change can be explained by looking at the "rise" (y) over the "run"(x)
The rate of change for the second option is 2. We know this because...
Rise(2)
----------
Run(1)
Try looking at one of the points, now go up 2 and over 1, you should now be at the second point, do it again but twice, you should now be at the third point. A proportional relationship must also go through the origin (0,0)
Answer:
Step-by-step explanation:
2x²+8=80
2x²=80-8=72
x²=72/2=36
x=±√36
x=±6
so x=6 is one solution other is x=-6
14.4, if my calculator was correct
