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
replace the 1st equation into the 2nd one for y
-8x-4(2x-5) = -20
-8x-8x+20 =-20
-16x+20 = -40
-16x=-40
x = 5/2 = 2.5
y = 2x-5 - 2(2.5) - 5 = 5-5 = 0
one solution (2.5,0)
