2968+9912=12,880 When you round 12,880 it makes 13,000 So your answer will be B 13,000 Hope this helps!
In this case they are like terms as both terms have x.
To simplify the expression we add the coefficients. Doing so, we have:
4. 78x + x = 5.78x
The answer is 5.78x
2x + 7 = 3x - 7
3x - 2x = 7 + 7
x = 14
2x + 7 + 12y + 1 = 180
2(14) + 12y + 8 = 180
28 + 12y + 8 = 180
36 + 12y = 180
12y = 180 - 36 = 144
y = 144/12 = 12
x = 14, y = 12
