Answer:
x = 6
Step-by-step explanation:
Assuming the equation is
- 
= - 4
Multiply through by 6 ( the LCM of 3 and 2 ) to clear the fractions
2(2x + 3) - 9x = - 24
4x + 6 - 9x = - 24
- 5x + 6 = - 24 ( subtract 6 from both sides )
- 5x = - 30 ( divide both sides by - 5 )
x = 6
Answer:
It will take 11 robots to do the same job as the 15 humans
Explanation:
Given:
<em>Workers in use = 15</em>
<em>Each worker can move an average of 15 boxes per minute.</em>
<em>A robot has been built that can move an average of 21 boxes per minute</em>
15 worker would move:
15 * 15 boxes = 225 boxes per minute.
The number of robots it will take to move 225 boxes is:
225/21 = 10.7
It will take 11 robots to do the same job as the 15 humans
