To make the two expressions equivalent, we need to find the value for "blank" that makes the two expressions equal.
The first expression is -13.8x + blank.
The second expression, -4.6(3x-2.8) + 2.5, can be simplified as follows:
-4.6 * 3x = -13.8x
-4.6 * (-2.8) = 12.88
So, the value for "blank" that makes the two expressions equivalent is 12.88.
Therefore, the answer is A. 12.88.
The first expression is -13.8x + blank.
The second expression, -4.6(3x-2.8) + 2.5, can be simplified as follows:
-4.6 * 3x = -13.8x
-4.6 * (-2.8) = 12.88
So, the value for "blank" that makes the two expressions equivalent is 12.88.
Therefore, the answer is A. 12.88.
