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 by subtracting 21 1/5 from both sides:
h = 30 - 21 1/5
h = 30 - 106/5
h = 150/5 - 106/5
h = 44/5
Therefore, Richard needs to work an additional 44/5 hours, or 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 + 2115 = h = hours
