Question

evaluate 5e+5-7F when e =6 and F= 5

Answer 1

If the expression is: 5e + 5 - 7f, which is what I think you meant, and e = 6 and f = 5,then you just need to substitute the 6 in for the "e" in the expression and the 5 in for the "f" in the expression, like this:

5(6) + 5 - 7(5)

Now, use your order of operations. So PEMDAS says that we will do the multiplication first

5 x 6 is 30 and 7 x 5 is 35

30 + 5 - 35

Now we perform the addition and subtraction, but since they have the same priority according to the order of operations, we will just move left to right.

30 + 5 = 35

Then 35 - 35 = 0

So the answer is 0. Here is how your work should look:

5e + 5 - 7f, when e = 6 and f = 5

5(6) + 5 - 7(5)

30 + 5 - 35

35 - 35

0
