Answer:

1.) n = - 5/2

2.) No solution

3.) n = - 2/5

Step-by-step explanation:

1.) n(- 2) = - 1 - (- 2) + 4

- 2n = - 1 + 2 + 4

- 2n = 5

n = - 5/2

2.) n(0) = - 1 - (0) + 4

0 = - 1 - 0 + 4

0 = 3

No solution

3.) n(5) = - 1 - (5) + 4

5n = - 1 - 5 + 4

5n = - 2

n = - 2/5

The wind blew away 24 of your muffins. That was 3/4 of them! How many are left?

forsale [732]

Set up a proportion:

3/4/24 = 1/x

Cross multiply:

3/4x = 24

Divide 3/4 to both sides or multiply by its reciprocal, 4/3:

x = 24 * 4/3

x = 96/3

x = 32

So you had a total of 32 muffins, now subtract this from the amount that blew away to find out how many you have left:

32 - 24 = 8

So you have 8 muffins left.
