Step-by-step explanation:
There are 20 chips in total.
P(red) = 8/20 = 2/5
P(not green) = 16/20 = 4/5
P(yellow or green) = 9/20
117.93 is greater than 117.859 by .035.
32 quizzes. If you make a proportion of quiz/weeks it would be 16/4 = x/8. Multiply by 2.
2x-y=7
y=2x+3
Substitute (2x+3) in for y in the first equation
2x-(2x+3)=7
2x-2x-3=7
-3=7
Becuase -3 does not equal 7 the answer is no solution
