A candy store sells mints in 1/4, 1/2 , and 3/4 lb packages. John purchases several packages of each weight.

KiRa [710]

For this problem, just multiply the fractions by the amount of packages purchased.

6 * 1/4 = 1 1/2

8 * 1/2 = 4

7 * 3/4 = 5 1/4

The populations of two cities after t years can be modeled by -150t+50,000 and 50t+75,000 . What is the difference in the popula

creativ13 [48]

Answer:

The difference in the populations of the cities when t=4 is 25,800.

Step-by-step explanation:

Given equations each of the city:

-150t+50,000

and

50t+75,000

To find the difference between the population when t=4, we first have to solve both equation when t=4.

For both equations, substitute 4 into t:

-150(4) + 50,000 = 49,400

50(4) + 75,000 = 75,200

Now subtract 49,400 from 75,200 and you get 25,800.

The difference in the populations of the cities when t=4 is 25,800.

These 2 terms cannot be simplified any further, but if you are looking to factor the expression, that would be -x(x+9)
