X + 2x = 1200
3x = 1200
x = 1200/3
x = 400
Here is what I got. I used the website called desmos. I hope this helped,.,
2.40/12 = x/16
then that would mean 12x= 2.40(16)
which equals 12x= 38.4, then divide 12 by both sides, getting you 3.2 so the answer is it would cost her $3.20 cents to by 16 lemons
9+2/3x<1
-9 -9
cross 9-9 out and your 1 becomes a -8
and left with
2/3x<-8
multiply 3 by 2/3 and that cancels 2/3 out. also multiply 3 by your -8
x = -24
