Answer:
The inverse is (x+3)/7
Step-by-step explanation:
y = 7x-3
Exchange x and y
x = 7y-3
Solve for y
Add 3 to each side
x+3 =7y-3+3
x+3 = 7y
Divide each side by 7
(x+3)/7 = 7y/7
(x+3)/7 = y
The inverse is (x+3)/7
11 blue
2 green
7 brown
total is 20 card
7 out of that 20 are brown
so x out of 100% are brown
7/20=x/100 - cross multiply
700=20x
x=700/20
x=70/2
