Richard is working as a part time library assistant at a university he needs to work for a total of 30 hours a week for the first three days of the week he worked 21 1/5 hours complete the working equation the represents the number of hours ,h, Richard needs to work to reach 30 hours for the week and solve the equation
To find the number of hours, h, Richard needs to work to reach 30 hours for the week, we can use the equation:
h + 21 1/5 = 30
First, let's convert 21 1/5 to a fraction. We can rewrite it as:
21 + 1/5 = 21 + 1/5 * 1 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21 + 1/5 = 21.2
Now, we can substitute this value in the equation:
h + 21.2 = 30
To solve for h, we can subtract 21.2 from both sides of the equation:
h + 21.2 - 21.2 = 30 - 21.2
This simplifies to:
h = 8.8
Therefore, Richard needs to work for 8.8 hours to reach a total of 30 hours for the week.
