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=53y 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,∞)
