Question

Nalia worked 3.5 hours more than lisa together they worked a total of 18 hours lisa worked h hours

Answer 1

7.25 and 10.75 Hours

Explanation:

Total hours Nalia and Lisa worked = 18 Hours

Nalia worked 3.5 hours then Lisa which is
`h` hours

⇒
`h + (h + 3.5) = 18`

`2h + 3.5 = 18\\2h = 18 - 3.5\\2h = 14.5\\h = (14.5)/(2) \\h = 7.25`

Lisa has worked for 7.25 hours

Nalia has worked for = 7.25 + 3.5 = 10.75 hours
