Evaluate b+7/2a for a=-4 and b= -6

Answer 1

To evaluate the expression b + 7/2a when a = -4 and b = -6, substitute the given values and perform the necessary calculations.

So, b + 7/2a becomes:
-6 + 7/2(-4)

Next, simplify the expression:
-6 + 7/(-8)

To simplify further, find a common denominator for -6 and -8, which is -8:
-6(-8)/(-8) + 7/(-8)

This simplifies as:
48/8 + 7/(-8)

48 divided by 8 is equal to 6, so the expression becomes:
6 + 7/(-8)

Finally, simplify further:
6 - 7/8

Therefore, when a = -4 and b = -6, the expression b + 7/2a evaluates to 6 - 7/8.
