Which sum or difference is equivalent to the following expression? 12x−8/4
The expression 12x - 8/4 can be simplified as follows:
12x - 8/4 = 12x - 2
So, the equivalent sum or difference is 12x - 2.
nvm its this \frac{12x-8}{4}
To simplify the expression (12x - 8)/4, we can begin by simplifying the numerator:
12x - 8
Now we can divide both terms by 4 to simplify the expression further:
(12x - 8)/4 = 3x - 2
Therefore, the equivalent sum or difference is 3x - 2.

180 + 2x
180 + 2x
180x - 2
180x - 2
180 - 2x
180 - 2x
180x + 2
To represent Alvin's current weight at any time after x weeks, the correct expression would be:
180 - 2x
Therefore, the correct answer is 180 - 2x.

To evaluate the expression ad + c^2b for the given values of a = 10, b = 6, c = 3, and d = 5, we substitute these values into the expression:
ad + c^2b = (10)(5) + (3^2)(6) = 50 + 9(6) = 50 + 54 = 104
Therefore, the evaluation of the expression for the given values is 104.
