The answer to your question is 21 bikes and 6 trikes

Step-by-step explanation:

Data

27 seats

60 wheels

there are bikes and trikes

Process

1.- Remember that both bikes and trikes have only 1 seat, then there are 27 bikes and trikes.

2.- Bikes only have 2 wheels and trikes have 3 wheels.

3.- We know that there are in total 60 wheels, so let's guess

- There are 10 bikes that mean 20 wheels and 17 trikes, that means 51 wheels, total number of wheels = 17 + 51 = 71

- There are 15 bikes = 30 wheels and 12 trikes = 36 wheels

  Total number of wheels = 30 + 36 = 66

- There are 18 bikes = 36 wheels and 9 trikes = 27 wheels

 Total number of wheels = 36 + 27 = 63

- There are 21 bikes = 42 wheels and 6 trikes = 18 wheels

  Total number of wheels = 42 + 18 = 60 wheels

  DONE!!!

its 69.420

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
