Answer 2

To evaluate the expression 10a - 9b with a = 3/5 and b = 2.5, we substitute the given values into the expression:

10(a) - 9(b)

10(3/5) - 9(2.5)

Now, let's calculate the values:

10(3/5) = 30/5 = 6

9(2.5) = 22.5

Finally, we substitute the calculated values back into the expression:

6 - 22.5 = -16.5

Therefore, when a = 3/5 and b = 2.5, the value of 10a - 9b is -16.5.
