Question

The steps Quentin took to evaluate the expression 3m - 3+3 when m = 8
are shown below.
3m - 3 + 3 when m=8
3 x 8 = 24
24 - 3 =21
21 + 3 = 7
What should Quentin have done differently in order to evaluate the
expression?
divided (24-3) by (24x3)
divided (24-3) by (24-3)
subtracted (3 + 3) from 24
subtracted 3 from (24 +3)

Answer 1

Answer:

Subtracted 3 from (24+3)

Step-by-step explanation:

3m - 3 + 3

24 - 3 + 3

Since the adding and subtracting go left to right, you can do them in that order.

21+3 = 24.

Now which one gives us 24?

(24+3) - 3
