Question

What is the value of a(b-1) +
`(bc)/(2)` , if a=3, b=6, and c=5?

Answer 1

30

Explanation:

a(b-1)+(bc)/2

3(6-1)+(6*5)/2

3(5)+(30)/2

15+30/2

15+15

30

Answer 2

Hey there!

a(b - 1) + bc/2

= 3(6 - 1) + 6(5)/2

= 3(5) + 6(5)/2

= 15 + 30/2

= 15 + 15

= 30

Therefore, your answer is: 30

Good luck on your assignment and enjoy your day!
