During the first round of a game, Silas scores 15 points. He loses 30 points
during the second round and gains
10 points during his final turn. What is
Silas’ final score?

Step-by-step explanation:

If Silas scores 15 points during the 1st round, he will have 15 points after the 1st round.

After the 2nd round, he would have -15 points because he lost 30,

In the 3rd round, he would have -5 points because he gained 10 points

Hope this helps!

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
