The production rate of a steel factory is declining due to old machinery. over the last eight days production has dropped by 1.2 tons. what is the average rate of change in steel production over the eight days? express the answer in tons per day.

The average rate of change in steel production over the eight days is 0.15 tons per day

Step-by-step explanation:

Over the last eight days production has dropped by 1.2 tons.

Production dropped in 8 days = - 1.2

Production dropped in 1 day =

                                             =

So, the average rate of change in steel production over the eight days is 0.15 tons per day

x ≤ 11.20

Step-by-step explanation:

solve it like a regular equation

5x ≤ 67 - 11

5x ≤ 56

x ≤ 11 1/5

x ≤ 11.20
