Question

evaluate...17.5×3-21+7-3×12.5​

Answer 1

Answer:

We have,

17.5 × 3 - 21 + 7 - 3 × 12.5

Using BODMAS rule,

= (17.5 × 3) - 21 + 7 - (3 × 12.5)

= 52.5 - 21 + 7 - 37.5

= (52.5 + 7)  - 21 - 37.5

= 59.5 - 58.5

= 1. 0

Hence, the value of (17.5 × 3 - 21 + 7 - 3 × 12.5) is 1.

Step-by-step explanation:

Answer 2

Answer:

First of all, break it up.

17.5 x 3 = 52.5

Now you end up with:

52.5 - 21 + 7 - 3 x 12.5

Do order of operations:

3 x 12.5 = 37.5

You end up with:

52.5 - 21 + 7 - 37.5

Just do the simple math now:

52.5 - 21 = 31.5

Then:

31.5 + 7 - 37.5 = 1

Your answer is 1.
