So if 40% of college students scored above 70%, then 60% of college students scored below 70%.

Our equation would be: 0.60x=120
x=120/0.60
x=12000/60
So x equal 200 students took the math test

5a+5b+5c=-20<br> 4a+3b+3c=-6<br> -4a+3b+3c=9
tekilochka [14]
For 5a+5b+5c=-20

A= -4 - b - c

B= -4 - a - c

C= -4 - a - b

———————————

4a+3b+3c=-6

A= -3/2 - 3b/4 - 3c/4

B= -2 - 4a/3 - c

C= -2 - 4a/3 - b

———————————

-4a+3b+3c=9

A= -9/4 + 3b/4 + 3c/4

B= 3 + 4a/3 - c

C= 3 + 4a/3 - b
