Answer 1

To evaluate 3a + 5 by substituting each value for a, you substitute the given values of a into the expression and simplify.

Step-by-step explanation:

To evaluate 3a + 5 by substituting each value for a, we can simply substitute the given values of a into the expression.

1. For a = 7, the expression becomes 3(7) + 5 = 21 + 5 = 26.
2. For a = 0, the expression becomes 3(0) + 5 = 0 + 5 = 5.
3. For a = -3, the expression becomes 3(-3) + 5 = -9 + 5 = -4.
4. For a = 1/3, the expression becomes 3(1/3) + 5 = 1 + 5 = 6.
5. For a = -2/3, the expression becomes 3(-2/3) + 5 = -2 + 5 = 3.

Therefore, the values of 3a + 5 for each given value of a are: a) 26, d) 5, f) -4, g) 6, h) 3.
