Justice hopes to build a fence around his garden he measures and determined that he needs 24 feet of fencing when he arrives at
Sunny_sXe [5.5K]

Answer:

It  will cost  $72 Justice to fence in his garden.

Step-by-step explanation:

Total length of the fencing around the garden =  24 feet

Cost of fencing per inch = $0.25

Now, as we know 1 foot  =  12 inches

⇒  24 feet =  24 x 12 inch  = 288 inches

⇒ 24 feet  =  288 inches

Hence, the total length of  fencing   =  288 inches.

Now, Total cost of Fencing

=Total length of fencing x Cost of fencing par inch

=  288 inches x ($0.25)

=  $ 72

or, the total cost of fencing = $72

Hence, it  will cost  $72 Justice to fence in his garden.

Graph the systems of equations. {2x+y=8 −x+2y=6 Use the Line tool to graph the lines.
Nitella [24]

Answer:

See attachment

Step-by-step explanation:

We want to graph the system

2x+y=8

-x+2y=6

Let us rewrite the lines in slope intercept form:

y=-2x+8

y=\frac{1}{2}x+3

The first line has a slope of -2 and a y-intercept of 8

The second line has a slope of 1/2 and a y-intercept of 3

We can no graph the lines as shown in the attachment.
