Question

PLEASE HELP!!! I really need help with this.

Answer 1

M. 2.5n - (-8.2) = 26. 7

to find n transpose

2.5n + 8.2 = 26. 7

2.5n = 26. 7 - 8.2

2.5n = 18.5

n = 18.5 ÷ 2.5

n = 7.4

L.
`(7a + 1)/(2)` = 18

7a + 1 = 18 ×2

7a + 1 = 36

7a = 36 - 1

7a = 35

a = 35 ÷ 7

a = 5

N.
`(2)/(5)` b + 1 = -11

`(2)/(5)` b = -11 -1

`(2)/(5)` b = -12

b = -12 -
`(5)/(2)`

b = 20

H. 5 -
`(9)/(2)` d = 32

-
`(9)/(2)` d = 32 - 5

-
`(9)/(2)` d = 27

d = 27 +
`(2)/(9)`

d = 6
