Which expression is NOT equivalent to the other three?
2 answers:
Answer:
c)
Step-by-step explanation:
A) 2x − 2.5 + 3x − 3 = 5x - 5.5
B)5(x-1.1) = 5x - 5*1.1= 5x - 5.5
D)5x - 5.5
But C) is not equivalent
5(x-5.5) = 5x - 5*5.5 = 5x - 27.5
Answer:
C
Step-by-step explanation:
A: You can combine like terms. 2x + 3x = 5x. 2.5 + 3 = 5.5 A = 5x - 5.5
B: You can use distributive property. 5x - 5.5
C: If you use the distributive property you get 5x + 27.
D: D is 5x - 5.5
So the only one that does not equal 5x - 5.5 is C.
