Answer 3

To evaluate the expression −a + (−b) when a = −3.7 and b = −7.5, you simply substitute the values of a and b into the expression and perform the arithmetic.

−a + (−b) = −(−3.7) + (−(−7.5))

Remember that the negative of a negative number is positive, so:

−a + (−b) = 3.7 + 7.5

Now, add the numbers:

−a + (−b) = 11.2

So, when a = −3.7 and b = −7.5, the value of −a + (−b) is 11.2.
