Two cyclists on a bike ride are Helena, age 73, and Jessica, age 19. Helena rode at a constant rate of 1 mile per 4 minutes and Jessica traveled at a constant rate of 1 mile per 2 minutes. Because

Helena is in the over-70 age group she has a head start of 5 miles. Jessica starts at the beginning

of the 24 mile route.

Write the system of equations that describes the relationship

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
