Really easy need answer by 10: 00 p. m. and will give brainleist. pls hurry if you have time answer other questions pls you.

a) The elephant eats 400 pounds of vegetation each day, therefore to find the total amount v it has eaten after a certain number of days d, just multiply 400 by d:

v = 400d

b) Plug in different values of d to find v:

For d = 1, v = 400(1) = 400

For d = 2, v = 400(2) = 800

For d = 3, v = 400(3) = 1200

c) The ordered pairs to graph are (d, v) for various values of d, for example:

(0, 0), (1, 400), (2, 800), (3, 1200)

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
