Answer:
[tex]d=\frac{1}{4}[/tex]
Step-by-step explanation:
[tex]-16(d+1)=-20[/tex] (given)
[tex]-16d-16=-20[/tex] (expand the brackets)
[tex]-16d=-4[/tex]
Hope this helps :)
d = 1/4
- 16 (d + 1) = - 20
- 16d - 16 = - 20
- 16d = -20 + 16
- 16d = - 4
d = [tex]\frac{-4}{-16}[/tex]
d = [tex]\frac{1}{4}[/tex]
