part one: -2/9x +7 < 5

part two: x > 9

Step-by-step explanation:

Simplify both sides of the inequality.

Subtract 7 from both sides.

Multiply both sides by 9/(-2).

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
