Which expression and value represents 100 less than 3 times the sum of 18 and 2?
3 × (18 + 2) – 100; –44
3 × (18 + 2) – 100; –40
100 – 3 × (18 + 2); 40
100 – 3 × (18 + 2); 48

it should be number 3; 100-3x(18+2); 40

100 – 3 × (18 + 2); 40

Step-by-step explanation:

Which expression and value represents 100 less than 3 times the sum of 18 and 2?

First, let's consider "the sum of 18 and 2".

18 + 2

Now, "3 times the sum of 18 and 2".

3 × (18 + 2)

Then, "100 less than 3 times the sum of 18 and 2".

100 - 3 × (18 + 2)

If we solve this expression using the PEMDAS rule, we get

100 - 3 × (18 + 2)

100 - 3 × (20)

100 - 60

40

1/3 + 1/5 = 8/15.
