The first one should be read as between 75 and 97 inclusive. That means you are using ≤
75 ≤ x ≤ 97 As a compound inequality this is
75 ≤ x ; x ≤ 97
The second one is just a bit harder. That's because a place in Ohio probably could go down to - 36. Again, both ends of the inequality use ≤
-36 ≤ x ≤ 20 As a compound inequality
-36 ≤ x; x ≤ 20
I'm not sure if you should be including units like 20°F. If you are, add them in.
The y-interval shows exponential increase rather than linear increase.
Answer:
x = 30.66°
Step-by-step explanation:
The sum of the interior angles of a hexagon is 720°
Each angles are x^0, (5x - 103); (2x + 60), (7x - 31), (6x -6), and (9x - 100),
we add all these angles together
x^0 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100) = 720
x^0 = 1
1 + (5x - 103) + (2x + 60) + (7x - 31) + (6x -6) + (9x - 100)
1 + 5x - 103 +2x + 60 + 7x -31 + 6x - 6 + 9x - 100 = 720
1 - 103 + 60 - 31 - 6 - 100 + 5x + 2x + 7x + 6x + 9x = 720
1 - 180 + 29x = 720
-179 + 29x = 720
29x = 720 + 179 = 889
x = 889/29 = 30.655 ≅ 30.66°
$48.31/23=$2.10. $2.10x18=$37.81
