The Least Common Multiple (LCM) of 42 and 70 would be 210 and u can find out how to find the LCM by doing the greatest common divisor method.
Lets x is the number of miles
Car Stars Auto Rental charges $35 a day plus $0.25 per mile = 0.25x + 35
Car Express Auto Rental charges $17 a day plus $0.40 per mile =0.40x + 17
0.25x + 35 = 0.40x + 17
0.25x -0.40x = 17 - 35
-0.15x = -18
x = -18 / -0.15
x = 120
answer: <span>D. 120 miles </span>
You can can copy a line segment by making sure the line is straight
Answer:
T1 = 975 / (205 + V) flying with wind
T2 = 975 / (205 - V) flying against wind
T2 = T1 + 2
975 * {1 / (205 - V) - 1 / (205 + V)] = 2
(205 + V + V -205) / (205^2 - V^2) = 2 / 975
V^2 + 975 V - 42025 = 0 rearranging
V = 41.3
Values of flying are 246.3 and 163.7
Check:
T1 = 975 / 246.3 = 3.96 hrs
T2 = 975 / 163.7 = 5.96 hrs
