If a = 7 and b = 4, what does 2a + 3b equal?

If a = 7 and b = 4, what does 2a + 3b equal?

• A. 24
• B. 26
• C. 30
• D. 22

Answer: (B)

To find the value of the expression \(2a + 3b\) when \(a = 7\) and \(b = 4\), you first substitute the values of \(a\) and \(b\) into the expression. 1. Calculate \(2a\): \(2a = 2 \times 7 = 14\) 2. Calculate \(3b\): \(3b = 3 \times 4 = 12\) 3. Add the results together: \(2a + 3b = 14 + 12 = 26\) Therefore, the value of \(2a + 3b\) is 26. This corresponds to the correct answer, which reflects the accurate calculation of the expression by substituting the values for \(a\) and \(b\) and combining the results.

To find the value of the expression (2a + 3b) when (a = 7) and (b = 4), you first substitute the values of (a) and (b) into the expression.

1. Calculate (2a):

(2a = 2 \times 7 = 14)

2. Calculate (3b):

(3b = 3 \times 4 = 12)

3. Add the results together:

(2a + 3b = 14 + 12 = 26)

Therefore, the value of (2a + 3b) is 26. This corresponds to the correct answer, which reflects the accurate calculation of the expression by substituting the values for (a) and (b) and combining the results.
