Question

Select the correct answer. If \(a = 4\), what is the value of the expression \(12 - 2 - 4\)?

a) \(2/4\)
b) \(4\)
c) \(11\)
d) \(12\)

Answer 1

The value of the expression 12 - 2 - 4, when a equals 4, is 6. We calculate this by performing the subtraction in the order given, first 12 minus 2, which is 10, and then 10 minus 4, which gives us 6.

Step-by-step explanation:

If a = 4, to find the value of the expression 12 - 2 - a, we substitute the value of a into the expression. So the expression becomes:

12 - 2 - 4

Now, perform the calculation by subtracting in order from left to right:

First, subtract 2 from 12, which gives us 10.

10 - 4

Then, subtract 4 from 10, which leaves us with 6.

Therefore, the value of the expression is 6, which corresponds with option d. None of the other options listed (2/4, 4, 11, or 12) are correct.
