Evaluate 4 − 0 . 2 5 g + 0 . 5 h 4−0.25g+0.5h4, minus, 0, point, 25, g, plus, 0, point, 5, h when g = 1 0 g=10g, equals, 10 and h = 5 h=5h, equals, 5.

Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

4

For this case we have the following expression:

We must evaluate the expression for the following values:

Evaluating the expression we have:

Rewriting we have:

Evaluating the expression we have that the result is equal to 4.
