Get started for freeFREIGHT TRAINS A train with 150 freight cars is used to haul two types of grain. Each freight car can haul 97.3 tons of barley or 114 tons of corn. Let \(n\) represent the number of freight cars containing corn. Which function correctly represents the total weight the train can haul? $$ \text { A. } W=97.3(150-n)+114 n \quad \text { B. } W=97.3 n+114(150-n) $$
FREIGHT TRAINS A train with 150 freight cars is used to haul two types of grain. Each freight car can haul 97.3 tons of barley or 114 tons of corn. Let \(n\) represent the number of freight cars containing corn. If 72 freight cars contain barley, what is the total weight the train is hauling?
RECIPROCALS Find the reciprocal. $$ \frac{1}{121} $$
Evaluate the expression. $$ [(12 \cdot 9) \div 6]-13.5 $$
COMBINING LIKE TERMS Apply the distributive property. Then simplify by combining like terms. $$ 3 t(t-5)+6 t^{2} $$
