There are 112 seats in the school auditorium. there are 7 seats in each row. there are 70 people seated, filling up full rows of seats. how many rows are empty

you divide 112 by 7 to find out how many rows there is and you get 16. there is 16 rows.  Then you divide 112 by 16 and you get 7.

There is 7 rows that is empty

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
