Answer:
4 days and 18 hours.
Step-by-step explanation:
1440 Watt hours = 1 day
6840 Watt hours = x
<em>Cross multiply.</em>
1440*x = 6840*1
1440x = 6840
<em>Divide both sides by </em><u><em>1440.</em></u>
1440x/1440 = 6840/1440
x = 4.75 days
4.75 days is <u>4 days and 3/4 of a day; because 3/4 = 0.75</u>
<em>We have to find 3/4 of 1 day.</em>
<u>1 day is 24 hours.</u>
3/4* 24
<em>Divide 24 by 4.</em>
3*6 = 18
So, 18 hours.
Therefore a light bulb consumes 6840 Watt hours in 4 days and 18 hours.

3x3
9x1
Factors of 49 are:
7x7
49x1
Only 3x3 and 7x7 equal 42 when you expand it out (3x - 7)(3x - 7) = 0
x = 7/3
