30

Answer 1

can anybody help me with this question??? plzzz

Answer 2

f + s =150
2f + 3s = 390

solve the system of equations

Answer 3

what do i solve for f or s

Answer 4

same as the other system of equations problems i solved for you

you could either use substitution here or just straight up subtract the equations

to substitute
f = 150 - s

2(150 - s) +3s = 390 then solve for s

straight up subtraction (which i think is easier)

2f +2s = 300
- (2f +3s = 390)
--------------
-s = -90

s = 90

plug s into f + s = 150

f +90 = 150

f = 60

Answer 5

so 90 sophomores and 60 freshmen

Answer 6

o ok so the answer is 60

Answer 7

no

Answer 8

look at the question

Answer 9

you plug 60 into f , 60 +90=150
