50*x=80 (x=percent in decimal form)
x=1.6 (divide both sides by 50)
Doubke check:
50*1.6=80
80=80
Convert 1.6 into a percent:
1.6 -> 160%
Answer:
f ^-1 (x) =7X/5 - 2/5
Step-by-step explanation:
A. (140x110)+[(50x70)/2] = 15,400+1750= 17,150cm^2
b. (4x6)/2= 12cm^2
Answer:
2/5
Step-by-step explanation:
The slope of the line
y=2/5x-4
is 2/5 since it is in the form y = mx+b where m is the slope
Parallel lines have the same slope so a line that is parallel to y=2/5x-4 has a slope of 2/5
