Step-by-step explanation:
The perimeter is the sum of the measures of the 3 sides.
Sum the sides and equate to 75, that is
2x - 9 + 3x + 4 + 2x + 3 = 75, that is
7x - 2 = 75 ( add 2 to both sides )
7x = 77 ( divide both sides by 7 )
x = 11
Thus
AB = 2x - 9 = 2(11) - 9 = 22 - 9 = 13 m
BC = 3x + 4 = 3(11) + 4 = 33 + 4 = 37 m
AC = 2x + 3 = 2(11) + 3 = 22 + 3 = 25 m
The answer is the point of intersection, (2,1)
Note that on a normal day, it takes him <span>1/3</span> hour to get to school. However, today it took <span><span><span>1/2 mile </span><span>2 mph</span></span>=1/4</span> hour to walk the first <span>1/2</span> mile. That means that he has <span>1/3−1/4=1/12</span> hours left to get to school, and <span>1/2</span> mile left to go. Therefore, his speed must be <span><span><span>1/2 mile</span><span>1/12 hour</span></span>=<span>6 mph</span></span>, so 6 is the answer.
