Question

20. 5x<15
= x<3

21. -6+>18
=t<-3

22. Y/3 < 2
=y <6
Explain pleasee

Answer 1

On #20 5x < 15 all you're doing is solving for x.. so divide on both sides by 5 and you get x < 3

#21 Im assuming its -6t > 18 so again solve for t by dividing by -6 but you got to remember when you divide by a negative number you have to flip the inequality so you get t < -3

#23 can be written as \[\frac{1}{3}y < 6\] Multiply both sides by 3 to get y by its self so you have y < 2*3 or y<6
