Answer:
A
Step-by-step explanation:
There are two parts of an equation (including this one), the coefficient, and the variable.
The coefficient is a known number, written as a digit, whereas the variable is an unknown number, written as a letter to signify an unknown number.
So, the coefficient in the first term (or part of the equation) is -2. The coefficient in the second term is 9, and the variable in this equation is x.
(-2.9a + 6.8) + (4.4a - 7.3)
= -2.9a + 6.8 + 4.4a - 7.3
Combine like terms. All "a" terms can only be added to other "a" terms, and all non variable terms can only be added to other non variable terms.
= 1.5a - 0.5
Final Answer: D. 1.5a - 0.5
It will always be zero. Try plugging in a number for X. Let's say it's 1. So 6(1) - 6(1).... 6 - 6=0. Try some other values for you to prove it.
