Question

evaluate 5a + 8b divided by three when a=4 and b=5

Answer 1

To evaluate the expression 5a + 8b divided by 3, when a = 4 and b = 5, we substitute the given values into the expression and simplify.

First, substitute a = 4 and b = 5 into 5a + 8b:
5a + 8b = 5(4) + 8(5) = 20 + 40 = 60

Now, divide the result by 3:
60 divided by 3 = 20

Therefore, when a = 4 and b = 5, 5a + 8b divided by 3 equals 20.
