Answer:
11.00 pm
Step-by-step explanation:
Given that at 11:00 AM a bus left San Jose travelling to Los Angeles at 48 mph. Hence in 4 hours it would have travelled
48x4 = 192 miles
When the bus travelled 192 miles a motorcyclist started in the same direction with speed 72 mph
Difference in speed per hour = 72-48 = 24 mph
TO cover the distance of 72 miles, time taken for the motorcycist would be
192/24 = 8 hours
In 8 hours or at 11.00 p.m. motorcycle will catch upto the bus,
Answer:
Aaron=12 Ben=24 Caleb=29
Step-by-step explanation:
Aaron=x
Ben=2x
Caleb=2x+5
x+2x+2x+5=65
5x+5=65
-5 on both sides
5x=60
divide by 5 on both sides
x=12
You then substitute this answer with ben and Caleb
ben= 2x (2*12) =24
caleb= 2x+5 (24+5)=29
Answer: x=3, y=4
Step-by-step explanation:
We are going to use the elimination method to solve this since the x values have inverse of each other. We are going to add the 2nd equation to the 1st and we will get: y=-4 then plug y=-4 into one of the equations, then solve for x. 4(x)+5(-4)=-8, 4x-20=-8, 4x=12, x=3. So x=3, y=4
The top question is B. 30, because you have to set 7y-30 equal to 4y+60 since both lengths are the same.
