Answer:
46 mph and 61 mph
Step-by-step explanation:
Distance=speed*time
Let speed of one bus be x and another x+15
After 3 hours
First bus would have traveled 3x while second bus 3(x+15)=3x+45
Total distance= 3x+3x+45=6x+45
6x+45=321
6x=321-45=276
x=276/6=46 mph
x+15=46+15=61 mph

From the markings and lines, we can tell this is an equilateral triangle. Since it is an equilateral triangle, we know that each angle is 60°.
Using this information, we can make and solve an equation:
8y - 4 = 60° <em>(we know that it is equal to 60°, since it is an equilateral triangle)</em>8y = 64° <em>(we added both sides by 4 to get the y's alone on one side)</em>y = 8° <em>(we divide both sides by 8 to find out what just y is)</em>-------------------------------------------------------------------------------------------------------------Answer:
So y is equal to 8°
Answer: a line contains at least two points
Step-by-step explanation:
through two points there can be more than one line so the first one is incorrect.
the entire line doesn't have to be on the plane so the third one is incorrect.
there can be more than one point of intersection so the fourth one is incorrect.
