Answer:

Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.

Step-by-step explanation:

18 ÷ 10 = 1.8 (Lisa's rate)

14 ÷ 8 = 1.75 (Marie's rate)

1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)

1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)

Answer:

The correct answer is C. Parasite.

Step-by-step explanation:

Parasitism describes the phenomenon within the animal and plant world that an organism or virus (parasite) misuses a usually considerably larger organism of a different species as a host. The host serves the parasite for food supply (mostly in the form of blood or other body secretions) and in some cases also as a long-term habitat. The host's health is damaged by the parasite, but usually remains alive. The consequences of parasitic infestation range from sting or bite injuries from massive physical complaints to serious infectious diseases and even death in extreme cases. The best known and most widespread human parasites are human lice, mosquitoes and various types of ticks and worms.

Answer:

X+2y=4

4+2y=x

2(2+y)=x

2x-2y=5

2(x-y)=5

x-y=5/2

Answer:

(x, y) = (3, 1/2)

Step-by-step explanation:

x + 2y = 4

2x - 2y = 5

There is more than one way to do this. I will do it by substitution.

From the first equation, x + 2y = 4, so x = (-2y) + 4

Now, in the second equation, I will replace x with (-2y + 4)

2(-2y + 4) - 2y = 5

-4y + 8 -2y = 5

-6y + 8 = 5

-6y = -3

6y = 3

y = 3/6

--------------------------------->  y = 1/2, one part of the answer

Now I can go back to the first equation, and relpace 'y' with 1/2

x + 2(1/2) = 4

x + 1 = 4

----------------------------------->  x = 3, the other part of the answer

So now we believe the solution is (x, y) = (3, 1/2)

Now check the answer, back in the original equations!!

------> In the first equation, we would have 3 + 2(1/2) = 4.

                                                                       3 + 1 = 4

                                                                       That is true

-------> In the second equation, we would have 2(3) - 2(1/2) = 5

                                                                                6 - 1 = 5

                                                                          That is true

Our answer is found and checked.
