Answer:

  78 km/h

Step-by-step explanation:

Let s represent the speed of the slower car. The total speed of the two cars is their closing speed:

  (s) + (s+14 km/h) = (340 km)/(2 h)

  2s + 14 km/h = 170 km/h . . . . . simplify

  s + 7 km/h = 85 km/h . . . . . . . . divide by 2

  s = 78 km/h . . . . . . . . . . . . . . . . subtract 7 km/h

The rate of the slower car is 78 km/h.

Answer:

x = 4.

Step-by-step explanation:

I am assuming that you want to find the values of x and that WXYZ is a parallelogram.

In a parallelogram opposite sides are equal, therefore:

11x + 1 = 19x - 31

1 + 31 = 19x - 11x

32 = 8x

x = 32/8 = 4.

mart [117]

3 times 5 times 2.5 = $37.5

3 x 5 =15

15 x 2.5 =37.5

37.5 x 2 = 75 for both of them

I don't know if this is right or not, but that's how I would solve it!
