50% of 45 solution=90

Predict the height of a woman who's humerus is 40 cm long using H(x)=2.75x+71.48 solution= 181.48cm

Trains A and B are traveling in the same direction on parallel tracks. Train A is traveling at 40 miles per hour and train B is traveling at 50 miles per hour. Train A passes a station at 2:10 A.M If train B passes the same station at 2:22 A.M., at what time will train B catch up to train A? = 3:35 A.M

Solve by elimination 2x+3y=2, 4x+6y=4= no solution

solve by substitution 7x+5y=-29, x=5-3y solution= (-7,4)

5/4x+1/8x=9/8+x solution= 3

solve using multiplication principle -4x>1/11 solution = -1/44

-0.1x<-6 solution = x|>60

solve the compound inequality 4>-3x+3 or 8≤-2x+5 solution is (-∞,-3/2]U(-1/3,∞)
