Answer: the number of hpurs that Fran can watch this week is lesser than 12
Step-by-step explanation:
Let x represent the number of hours of television that Fran can watch in a week.
Fran is limited to watching television less than 12.6 hours per week. She has already watched 4.2 hours, and each show is 0.7 of an hour long. The inequality representing the situation is expressed as
0.7x + 4.2 < 12.6
0.7x + 4.2 < 12.6 - 4.2
0.7x < 8.4
x < 8.4/0.7
x < 12
Answer:
12
Step-by-step explanation:
Fran has wached 4.2 hours of tv out of 12.6, if the equasion is curect that means that she has wached 6 shows already.
From here there is two ways to do his one is to look at how meny shows she can watch in 12.6 hours and subtract how meny shows she has wached from it and then convert back to desimals.
The other way to do this( the better way) is to do 12.6-4.2=8.4 then do 8.4 / .7 and you would get 12
