Question

Does anyone know the answer to this I have tried everything but nothing works.

Answer 1

Let the number of miles = m

Inequality

0.75*m + 20 ≤ 65

Solution

0.75*m + 20 - 20 ≤ 65 - 20            Subtract 20 from both sides

0.75*m ≤45                                      Divide by 0.75

0.75*m / 0.75 ≤ 45/0.75

m ≤ 60

Conclusion

The truck can be driven up to 60 miles.
