If a = 2 and b = 3, what is the value of 2a + 3b?

If a = 2 and b = 3, what is the value of 2a + 3b?

• A. 10
• B. 11
• C. 13
• D. 9

Answer: (C)

To determine the value of the expression 2a + 3b, first, substitute the values of a and b into the expression. Given a = 2 and b = 3, replacing a and b gives: 2(2) + 3(3). Now, calculate the values step by step. First, multiply 2 by a: 2(2) = 4. Next, multiply 3 by b: 3(3) = 9. Now, add these two results together: 4 + 9 = 13. This shows that the value of the expression 2a + 3b when a = 2 and b = 3 is indeed 13. Therefore, the correct answer aligns with this calculation, confirming that 13 is the appropriate conclusion for the given values of a and b.

Now, calculate the values step by step.

First, multiply 2 by a:

2(2) = 4.

Next, multiply 3 by b:

3(3) = 9.

Now, add these two results together:

4 + 9 = 13.

This shows that the value of the expression 2a + 3b when a = 2 and b = 3 is indeed 13. Therefore, the correct answer aligns with this calculation, confirming that 13 is the appropriate conclusion for the given values of a and b.
