Answer:
8.5 hours
Step-by-step explanation:
30 mins per page ( 15 )
so, 30 × 15 = 450
each hour is 60 minutes so 450 ÷ 60 = 7.5
then add the 1 hour that she already took to write the outline, so 8.5 hrs

Answer:
(x, y) = (7, - 1)
Step-by-step explanation:
given the 2 equations
x + 7y = 0 → (1)
2x - 8y = 22 → (2)
Rearrange (1) expressing x in terms of y by subtracting 7y from both sides
x = - 7y → (3)
Substitute x = - 7y in (2)
2(- 7y) - 8y = 22
- 14y - 8y = 22
- 22y = 22 ( divide both sides by - 22 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = - 7 × - 1 = 7
Solution is (7, - 1 )
