Question

Pls help with number 5 thx u

Answer 1

I think that says

`5 + 1.5(2d - 1) = 0.5`

Multiplying both sides by 2 to clear the decimals,

`10 + 3(2d -1) = 1`

`10 + 6d - 3 = 1`

`6d = 1 + 3 - 10`

`6d = -6`

`d = -6 / 6`

`d = -1`

Answer: d = -1

Check: 5 + 1.5(2(-1)-1) = 5 + 1.5(-3) = 5 - 4.5 = 0.5 checks, good
