Answer:
Step-by-step explanation: The answer for 7: is 7/2
8: 28/5.
9: 9/4
10: 24/5
If line DE is perpendicular to line HK, that means angle KHE is a right angle. Also, since angles GHE, KHE, and KHA are all on line AHG, those three angles should be supplementary. Therefore, we can set up the following equation:
(60 - x) + (2x - 6) + 90 = 180
x + 54 = 90
x = 36
Therefore, choice B is the value of x and Jeb’s answer is wrong.
Hope this helps!
So in 30 min will hike 2 1/4 miles =9 of those 1/4 miles therefore in 10 min will hike 9/3 =3 of those 1/4 miles = 3/4 of a mile
3/4 mile in 10 min;
(3/4)• 4 = 3 miles in 40 min;
6 miles in 80 min;
9 miles in 120 min;
12 miles in 160 min;
15 miles in 200 min;
18 miles in 240 min or 4 hours
