Question

evaluate 3w+(8-v)t if w=4, v=5 and t=2

Answer 1

well, start off by replacing the variables (letters) with the matching numbers

3w + (8-v)t = 3(4) + (8-5)2, agreed?

Answer 2

yes

Answer 3

ok, now time for a little set of math rules called, "the order of operations". we use the name PEMDAS to help us remember what order to do our operations in.

it stands for:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

Answer 4

so going back to our problem:

3(4) + (8-5)2

we have (8-5) in parentheses, let's simplify that first

8-5 = ?

Answer 5

3

Answer 6

correct, now we move to multiplication

3(4) + 3(2)

first we multiply 3(4) and 3(2), which gives us

12 + 6, agreed?

Answer 7

yup

Answer 8

then we finish up with addition

Answer 9
