Answer:

7 or -9, dependent on if 2y is or is not negative

Step-by-step explanation:

If 2y is NOT negative

katrin [286]

Let x = number of months.

Let y = total number of fish in pond.

6% of 3,000 = 180 fish

We can use an equation to help us with this problem.

y = 3,000 + 180x - 400x. Combine like terms.

y = 3,000 - 220x. Plug 9 in for x.

y = 3,000 - 220(9). Solve for y

y = 1,020.

There are 1,020 fish in the pond after 9 months.

Carli and Angela share a cell phone plan and split the bill each month. Last month, their total bill was $109. Carli went over h
Vikentia [17]
For this case, the first thing we must do is define variables.
 We have then:
 x = Carli's bill
 y = Angela's bill
 We have then:
 "their total bill was $ 109"
 x + y = 109
 "Carli went over her data limit on her phone, so her share of the bill was $ 15 more than Angela's"
 x = y + 15
 Answer:
 
A system of equations that represents this situation is:
 
x + y = 109
 
x = y + 15
