Tomato hornworms are infesting Jaime's tomato garden. He designs an investigation to determine if a pesticide or ladybug beetles will control the infestation better. Jaime used six tomato plants. He put hornworm insecticide
on three plants, and then released ladybugs into the garden. He observed that the plants with the insecticide
had fewer Hornworms than the plants with only ladybug beetles. The second year, Jaime used only insecticide
to control Tomato Hornworms, but the treatment was not as effective. How did the design of the investigation
make the results different for the second growing year?

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.

the answer is c a tornado
