One solution was found : t ≤ -13 (Last answer choice)
Pull out like factors :
-3t - 39 = -3 • (t + 13)
Divide both sides by -3
Remember to flip the inequality sign:
Solve Basic Inequality :
Subtract 13 from both sides to get t≤−13
Answer:
4:50 hrs to school activities
Step-by-step explanation:
the entire school day 6:10 hrs (with breaks)
so if we remove the breaks (which are 1:20hrs in total) we'll have 4:50hrs.
the equation would be: (the time the full day is)-(the total of breaks)= the school activity time.
so: 6:10hrs-1:20hrs= 4:50hrs
there's your answer. 4:50 hrs
*just remember i am working in the hrs format meaning 60 mins= 1hrs*
