Answer:

There are 14 pairs of Brand A sold.

Step-by-step explanation:

In order to find this, you need to set up a system of equations. You can set up on equation for the number sold:

A + B = 32

And you can set up one for the amount made:

30A + 35B = 1090

Now, in order to solve for the amount of A sold, multiply the first equation by -35 and add the two equations together.

-35A - 35B = -1120

30A + 35B = 1050

----------------------------

-5A = -70

A = 14

In a trolley ride around an amusement park, a child traveled from one signpost to a second signpost at a constant speed of 125 m
Inessa05 [86]

Answer:

Given speed of trolley = 125 meters per minute

Speed= 125 meters/minute\\\\Speed =\frac{125}{60}meters/second\\\\Speed=2.083m/s

Now we know that

Distance= Speed x time

Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than

Distance < 2.083 x 450 =937.5 meters

hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.

For the second case

since the time of travel is greater than 400 seconds

Thus the distance traveled is

Distance>2.083\times 400=833.2meters

which is greater than 800 meters.
