Question

Ab - 0.5b when a = 1 and b = 5

Answer 1

2.5

Explanation:

a = 1

b = 5

ab

= 1 x 5

= 5

0.5b

= 0.5 x 5

= 2.5

ab - 0.5b

= 5 - 2.5

= 2.5

Answer 2

2.5

Explanation:

ab - 0.5b

a = 1 and b = 5

(1)(5) - 0.5(5)

Multiply (1)(5) = 5

5 - 0.5(5)

Multiply -0.5(5) = -2.5

5 - 2.5

Subtract 5 - 2.5 = 2.5

2.5
