Answer:
72%
Step-by-step explanation:
Start by turning both percentages into decimals. To do this take the percent and divide it by 100. So, 60% = 60/100 or .6 and 80% = 80/100 or .8.
Next the student has already completed 20 quizzes. So, 50-20=30 remaining quizzes.
Quizzes already taken:

= 12 passed quizzes.
The remaining quizzes for the school year:

= 24 quizzes
So, Finally add them both together and divide by the total amount of quizzes:
12+24
= 36 passed quizzes

=.72
Now to convert it back into a fraction you multiply the decimal by 100.

= 72%
Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2
hope it helps
