Two buses depart two cities moving in the same direction. The speed of the first bus is 54 mph which is 60% of the speed of the
Mama L [17]

Answer:

The second city is 54 miles behind the first city

Step-by-step explanation:

The first bus is assumed to go ahead of the second bus and is moving at 54 mph. The second bus is moving at a speed such as 54 mph is 60% (0.6) of its speed.  

The speed of the second bus is then 54/0.6 = 90 mph

When 1 and a half hour has passed, the first bus has moved a distance of

X_1=54\times 1.5 = 81 miles

The second bus (behind the first bus) has moved

X_2=90\times 1.5 = 135 miles

The problem states they both meet in that time, it can only be possible if the second bus departed a distance 135 - 81 = 54 miles behind the first city

So, the second city is 54 miles behind the first city

How is the graph of y=2(3)^x+1 translated from the graph of y = 2(3)^x
umka2103 [35]

y=2​(3)x+1

−

y=2(3)x

y-y=2(3)x+1−2(3)x​


the answer would be 0=1


but if it is asking u if it is false or true it is


0=1 is false, therefore the system of equations has no solutions

Please help me find the equation xx
Lisa [10]

9514 1404 393

Answer:

  • (2x-10) +x +(x+10) = 180
  • x = 45
  • (2x-10)° = 80°
  • (x+10)° = 55°
  • x° = 45°

Step-by-step explanation:

The equation is an expression of the fact that <em>the sum of the angles in a triangle is 180°.</em>

  (2x -10)° +x° +(x +10)° = 180°

For the purposes of the answer box, I'd leave off the degree symbol:

  (2x -10) +x +(x +10) = 180

__

This simplifies to ...

  4x = 180

  x = 45

Then the angles (CW from top) are ...

  (2·45 -10) = 80°

  (45 +10)° = 55°

  (45)° = 45°
