The working equation that represents the number of hours Richard needs to work to reach 30 hours for the week is:
h + 21 1/5 = 30
To solve the equation, we need to isolate h. We can do this by subtracting 21 1/5 from both sides:
h + 21 1/5 - 21 1/5 = 30 - 21 1/5
This simplifies to:
h = 8 4/5
Therefore, Richard needs to work 8 4/5 hours to reach a total of 30 hours for the week.
During weekdays, 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 that represents the number of hours, h, Richard needs to work to reach 30 hours for the week and solve the equation. (1 point)
h + 21 1/5 =
h= Box hours
