B percent of something (x)
means: b/100 * x
ex: (2)
20% of 120 = 20/100*120 = 24
ex: (4)
18 = 40 % of x
means: 40*x/100 = 18
x=45
and so on
hope that helps

Answer:
8x= y
Step-by-step explanation:
from what a can see the line passes through the point (10,80) meaning for every 10 x there is 80y

You would subtract 1.60 from 29.20 to get 27.60. Then you would divide by two because there were two CDs and get $13.80
Answer:
y=6 x=8.49
Step-by-step explanation:
Since angles p and r are 45deg QP and QR are the same length.
the pythagorean theorem states that a^2+b^2=c^2.
so 6^2+6^2=72
the square root of 72 is 8.49.
so x or c = 8.49
7, sqrt(58), then 8. Hope this helps!
