The answer to this is C. The dinosaur is about 5 feet taller than the person.
Step-by-step explanation:
The reason why is because the human is 4 feet since it says that 1/2 inch on the scale is 2 feet and the human is 1 inch on the scale so the human is 4 feet.
The dino is 8 feet since it goes to 2 inches on the scale which means 8 feet. The difference between 4 and 8 is 4, so 5 feet is the approximate for this problem.
An infinite number of solutions means a coincident line...it is the same line 3y = 2x - 9...divide by 3 y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
The are moving towards each other at 50 mph and 40 mph which is the same as 90 mph. They are moving 90 mph closer to each other every hour so in 2 hours it would be 180 miles.
