Engineering A small bridge has a weight limit of 8000 pounds. A photographer wants to photograph at least 5 vehicles on the bridge. The cars weigh about 1800 pounds each and the motorcycles weigh about 600 pounds each. There must be at least one car and four motorcycles in the photo. Graph a system of linear equations to describe the situation. Give two combinations of cars and motorcycles that are solutions.

Multi-Step In a bowling lane, the distance (d) from the foul line to the center of
the Number 1 pin should be 60 feet and should vary from this length by no more
than _1 inch. 2
a. Convert 60 feet to inches.
b. Write and solve an absolute-value inequality that models the acceptable
distances from the foul line to the center of the Number 1 pin.
c. If the diameter of the base of the Number 1 pin is 4_1 inches, what is the shortest 8
possible distance between the foul line and the front of the Number 1 pin?
