Now for one revolution of the wheels, they cover the distance of on the ground.
For 20 revolutions, the distance covered will be 20 times this.
Thus
Which is our answer.
Answer:
32 CDs, 13 Videos
Step-by-step explanation:
You can represent this question using variables.
Let x = #CDs sold, Let y = #videos sold.
You can formula two equations with the information given:
3x + 7y = 187
x + y = 45
Substitute x into the equation above by reducing the equation below:
x + y = 45 -> x = 45 -y
Since we are now able to remove x from the equation, plug in your new value into the equation above.
3(45-y) + 7y =187
135 - 3y +7y = 187
135 + 4y = 187
4y = 52
y = 13
Knowing the value of y, simply plug in this y value to solve for x:
x + 13 = 45
x = 32
