We already know that the hourly rate for John is : 1/6 and the hourly rate for Rick is : 1/8. What we don`t know is a hourly rate for Molly and we will call it 1 / x.
The hourly rate for all together is: 1 / 3
An equation is:
1 / 3 = 1 / x + 1 / 6 + 1 / 8
1 / 3 = 1 / x + 4 / 24 + 3 / 24
1 / 3 = 1 / x + 7 / 24
1 / x = 1 / 3 - 7 / 24
1 / x = 8 / 24 - 7 / 24
1 / x = 1 / 24
1 / 3 = 1 / 24 + 1 / 6 + 1 / 8
The hourly rate for Molly is 1 / 24. Molly can paint the room alone for 24 hours.
Answer:
0.5
Step-by-step explanation:
The result of the evaluation of the equation given in the task content is; x =-2.
<h3>What is the solution of the equation?</h3>
It follows from the task content that the equation given whose solution is to be determined is;
3[-x + (2 x +1)]=x-1
The equation can be solved as follows;
-3x + 6x +3 = x-1
2x = -4
x = -2
