I need you guys to show work too please one by one make sure to answer every single one also this is apart of them from my homework packet so please make your answer count

5. $4.50

6. 40 photo albums

7. s ≥ 4.25

8. r ≤-2; filled circle on -2 going to the left

Step-by-step explanation:

5.

(4 + x ) / 2 =4.25

(multiply by 2)

4 + x = 8.5

(subtract 4)

x= 4.5

6.

60 = 5 + (n * 1 3/8)

(subtract 5)

55 = n * 1 3/8

(divide by 1 3/8)  

40 = n

7.

70 ≤ 36 + 8s

(subtract 36)

34 ≤ 8s

(divide by 8)

4.25 ≤ s

8.

9r + 3 ≤ -15

(minus 3)

9r ≤ -18

(divide by 9)

r ≤ -2

-1/2 +2

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
