24/30 divided by 2 gives
12/15 divided by 3 gives
4/5
4n = 3m - 1
4n = 3m - 1
Subtract 3m from both sides.
-3m + 4n = -1
Subtract 4n from both sides.
-3m = -4n - 1
Divide both sides by -3.
m = 4/3n + 1/3
m = 4/3n + 1/3
It's C. Number of students who scored "proficient" on chapter 7 is 16, and of those, only 3 scored "needs improvement" on 6. So the 3/16 represents those who were proficient at 7, but need improvement on 6
-5 x 2y = 22
2y = 22 / -5 which is -4.4
y = -2.2
Substitute:
-6x + 11 = 18
-6x = 7
x = 7 / -6
