Question

If a=18 and b=4 what does: a) ab, b) a/b, c) a+b*b, d) a-b+a*a/b equal?

Answer 1

Hello!

Since we are given the values of a = 18 and b = 4, we substitute the values of a and b into the given expression and solve. Remember to use PEMDAS!

A) ab - This problem is another way to write "a times b". So, we multiply 18 and 4 together to get the product.

18 · 4 = 72

B) a/b - In this problem, we are dividing 18 by 4.

18/4 = 4.5

C) a + b · b

18 + 4 · 4 (multiply)

18 + 16 = 34

D) a - b + (a · a)/b

18 - 4 + (18 · 18)/4 (simplify)

14 + (324)/4 (divide)

14 + 81 = 95

Final answers:

• a) 72
• b) 4.5
• c) 34
• d) 95
