If a=3 and b=5, find b (a+b)

a. 3/8
b. 5/8

Hi there!

First of all to begin we can switch out the variables for the given numbers to replace them. In our case a=3 and b=5. This is pretty simple.
Your new equation would look like -> 5 (3+5)

Remember that the number outside the parenthesis means to multiply. First of all we are going to do what's in the parenthesis. Keep in mind PEMDAS.

3+5 = 8

Now multiply 8 by the 5 that we mentioned earlier sitting outside the parenthesis.

8 × 5 = 40.

Your correct answer is 40.

I'm not so sure about the answer choices you have there. But closest to 40 is answer choice A.
Are your answer choices correctly typed? Because my 40 definitely doesn't match answer choice A or B.
Anyway, hope this helped you.

What is it steepest slope?
