Answer:
meters fence
Step-by-step explanation:
Ben needs to replace two sides of his fence.
The length of one side of fence =
meters
The length of other side of fence =
meters
to calculate the length of fence that Ben need to buy we will add the length of both sides.
+ 
=
+ 
= 
= 
=
meters
Ben need to buy
meters fence.
We take the value of F in the inequality by taking the inequalities in group. Let the first group be:
(1) -20 ≤ 59(F - 32)
Then, the second group would be,
(2) 59(F - 32) ≤ - 15
Calculating for the values of F,
(1) -20 ≤ 59F - 1888
1888 - 20 ≤ 59F
1868 ≤ 59F
F ≥ 31.66
(2) (59)(F - 32) ≤ - 15
59F - 1888 ≤ -15
59F ≤ 1873
F ≤ 31.75
The values of F are therefore,
31.66 ≤ F ≤ 31.75
