Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.Gavin works in the shipping department of a toy manufacturer. Toy cars weigh 1 kilogram apiece and are shipped in a container that weighs 7 kilograms when empty. Toy trucks, which weigh 2 kilograms apiece, are shipped in a container weighing 4 kilograms. When packed with toys and ready for shipment, both kinds of containers have the same number of toys and the same weight. What is the number of toys? What is the weight of each container?There are __ toys in each container, for a total weight of __ kilograms.
Q. Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.Gavin works in the shipping department of a toy manufacturer. Toy cars weigh 1 kilogram apiece and are shipped in a container that weighs 7 kilograms when empty. Toy trucks, which weigh 2 kilograms apiece, are shipped in a container weighing 4 kilograms. When packed with toys and ready for shipment, both kinds of containers have the same number of toys and the same weight. What is the number of toys? What is the weight of each container?There are __ toys in each container, for a total weight of __ kilograms.
Define Variables: Let x be the number of toy cars and y be the number of toy trucks. Since both kinds of containers have the same number of toys, we have:x=y
Calculate Weight of Toy Cars Container: The weight of the container with toy cars is 1 kilogram per car plus the weight of the empty container, which is 7 kilograms. So, the total weight of the container with toy cars is:Weight of toy cars container = 1×x+7
Calculate Weight of Toy Trucks Container: The weight of the container with toy trucks is 2 kilograms per truck plus the weight of the empty container, which is 4 kilograms. So, the total weight of the container with toy trucks is:Weight of toy trucks container = 2×y+4
Set Weight Equations Equal: Since both containers have the same weight when packed with toys, we can set the weights equal to each other:1×x+7=2×y+4
Substitute Variables: Using the fact that x=y, we can substitute y for x in the equation:1×y+7=2×y+4
Solve for y: Now we solve for y:1y+7=2y+47−4=2y−1y3=y
Find Total Weight of Toy Cars Container: Since x=y, we also have:x=3
Find Total Weight of Toy Trucks Container: Now we can find the total weight of each container. For the toy cars container:Weight of toy cars container = 1×x+7=1×3+7=10 kilograms
Find Total Weight of Toy Trucks Container: Now we can find the total weight of each container. For the toy cars container:Weight of toy cars container = 1×x+7=1×3+7=10 kilogramsFor the toy trucks container:Weight of toy trucks container = 2×y+4=2×3+4=10 kilograms
