You are an IT technician. You have built a 7-level rack in a server room that is 2/7 full of battery backups and 3/7 full of wireless routers. What fraction of the space in the server room is being used for battery backups and wireless routers?

is there any attachment? what are the equations?

the answer is (-4,-4)

hope this ! : d

1 1/7 hope i

step-by-step explanation:

8/7 = (1 * 7 + 1) / 7 = 1 + 1/7 = 1 1/7

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
