Answer:
7
Step-by-step explanation:
7
(n - 2)180 = sum of angles (six sides)
(6 - 2)180 = y
(4) 180 = y
720= y
115+110+x+25+x-30+x+x = 720
4x + 220 = 720
4x = 720 - 220
4x = 500
x = 500/4
x = 125
The answer is 216 miles. 1.5 hours is 90 minutes. Multiply 2.4 times 90.
2. Thumb is what makes it a trick question
54 / 2 2/3 =
54/1 / 8/3 =
54/1 x 3/8 = 162/8 = 20 1/4 miles per month
