Answer:
12.5
Step-by-step explanation:
We want to find 1/8 of 100 so we would write it as 100÷8 to get 12.5
Now we know that 12.5 is equivalent to 1/8 but let's double check.
12.5×8 is 100
1/8 ×8 is 8/8
100=8/8
Your answer is C: c = 2.50 + 2.50n
To get this answer I looked at the possible answers and inserted the numbers from the chart to see which fit.
In the given diagram, the traingles USW and UTV are similar triangles and thus the following ratio equality applies to them.
..........(Equation 1)
Checking the diagram given, we see that:
VT=y, WS=22, VU=8, ST=x-2
WU=WV+VU=12+8=20
TU=5
SU=ST+TU=(x-2)+5=x+3
Thus, substituting the required values in (Equation 1) we get:

Now, as can be clearly seen, to find y we will use the first two ratios as:


In a similar manner, to find the value of x we can use the last two ratios:

After cross multiplication we get:

Which can be simplified as:

Thus, 
Therefore, the required answer is:
x=9.5 and y=8.8
