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. 0.7x + 4.2 < 12.6 How many more shows can Fran watch this week?

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

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
