Question

A clown creates an equation that relates his data of each child´s head size to the length of the balloon he needs to make them a proper balloon-animal hat. For each child, he needs a ballon five times as long as the child´s head size, plus 4/5 of an inch extra. Complete a linear equation for a child A, where X is the size of the child´s head in inches and Y is the length of the balloon in inches.

Answer 1

If x is the size of the child's head, 5 times that would be 5x and "plus 4/5" is + 4/5 so the equation is y = 5x + 4/5.
