Answer:

1. n= -8

2. t= -11

3. p= -2

4. j= -4

5.w= -2.5 or -5/2

Step-by-step explanation:

1. 5(n-4) = -60

Distribute:

5n-20 = -60

Add 20 to both sides:

5n = -40

Divide both sides by 5:

n= -8

2. -3t+-8 = 25

Add 8 to both sides:

-3t = 33

Divide both sides by -3:

t = -11

3. 7p-8 = -22

Add 8 to both sides:

7p = -14

Divide both sides by 7:

p = -2

4. 2/5 (j+40) = -4

Distribute:

2/5j + 80/5 = -4

Simplify:

2/5j + 16 = -4

Subtract 16 from both sides:

2/5j = -20

Divide both sides by 2/5:

j = -20/5

j = -4

5. 4 (w+1) = -6

Distribute:

4w+4 = -6

Subtract 4 from both sides:

4w = -10

Divide both sides by 4:

w = -10/4 (simplified form is -5/2)

w = -2.5
