Question

I need help please. Thank you show your work please

Answer 1

3.5 because 5-1.5  =3.5

Answer 2

Let, the number of hours, that Julia still can watch TV = x

Equation would be: 1.5 + x ≤ 5

Solving: 1.5 + x ≤ 5

Subtract 1.5 from both sides, 
1.5 - 1.5 + x ≤ 5 - 1.5
x ≤ 3.5

In short, She can watch 3.5 hours at maximum

Hope this helps!
