Question

5. Evaluate for the given values: *
2 ÷ 6 + x + x - 5; use x = 1, and 2 = 6
1
2
-3
2

Answer 1

To evaluate the expression 2 ÷ 6 + x + x - 5 with x = 1, we substitute x with 1:

2 ÷ 6 + 1 + 1 - 5

Next, we simplify the expression according to the order of operations:

2 ÷ 6 is equal to 1/3

1/3 + 1 + 1 - 5

1/3 + 1 simplifies to 1 1/3 or 4/3

4/3 + 1 - 5

Now, we need to find a common denominator to add the fractions. The common denominator is 3.

4/3 + 3/3 - 15/3

To add the fractions, we add the numerators and keep the denominator the same. The denominators are equal because we found a common denominator.

(4 + 3 - 15)/3

Now, we can perform the subtraction in the numerator.

(7 - 15)/3 = -8/3

Therefore, the value of the expression 2 ÷ 6 + x + x - 5 with x = 1 is -8/3 or -2.6666...

So, the answer is -2.
