Answer:

Equation forms : m=9.5h

Step-by-step explanation:

Trina earns $28.50 tutoring for 3 hours.

So, per hour earnings of Trina are = \frac{28.50}{3}= 9.5 dollars

Let her total earnings be m

Let the number of hours she tutors be h

To establish an equation multiply the hourly rate by h.

m=9.5h

And when h = 2 hours;

m=9.5(2)

m = $19.

When h = 4.5 hours;

m=9.5(4.5)

m = $42.75

Elanso [62]
Since I don't see attachment, I guess the solution will be as follows:

1 & 3/4 , since 1 = 4/4, then it could be rewritten :


4/4 & 3/4, hence between these 2 fraction there is 2/4 or 1/2.
