Answer:
<u>42 Hours.</u>
Step-by-step explanation:
As an equation where y is the total pages and x is hours of class:
y=1+1x since she started with 1 page and does 1 page per hour.
Setting the total pages she needs as 43 (y=43) we get:
43=1+1x
Subtract one on both sides
42=1x
The 1 doesn't need to be written so
x=42
Therefore, it'll take her 42 hours to write all those notes.

Step-by-step explanation:
the light bulb uses 8100 total watts
(9-2)/9 x - 2/9 x = 95
7/9 x - 2/9 x = 95
5/9 x = 95
(5/5)/9x = 95/5
1/9 x = 95/5
1/9 x = 19
(9-2)/9 x= 19*(9-2)
7/9x = 19*(7)
7/9 x= 106
