There is 30 students from each grade so we have 30/120 already then add 12 from 9th grade math and add 10 more from 10th grade math, then add 7 from 12th grade math.
30 + 12 + 10 + 7 = 59
59/120 students.
Answer:
Factor of 12
= 2 × 2 × 3
Factor of 27

Answer:
The left and right sides would be the same length.
Set the two sides equal and solve for y:
10 = 2y +4
Subtract 4 from both sides:
6 = 2y
Divide both sides by 2:
y = 6/2
y = 3
