Question

Can someone show work for these answers here.I will give extra points if you answer

Answer 1

Explanation:

1. 3n+4n=28

7n=28

n=4

2. 2x+7-9=10

2x=10+2

2x=12

x=6

3. 3(a+2)=-5

3a+6=-5

3a=-11

a= -11/3

4. 2(3n-1)=19

6n-2=19

6n=21

n=7/2

5. 3x-5-x+1=10

2x=14

x=7

6. -3-5=5-2a+7

2a=20

a=10

7. -5(n-2)= -15

n-2=3

n=5

8. Let the cost of each fan be y.

6y+3y=1188

9y=132

∴ The cost of each fan is $132.
