Write an expression that is equivalent to the expression 4n-n+0.5n-2n
1 answer:
Answer:
1.5n
Step-by-step explanation:
The distributive property can be used to simplify expressions like this (collect terms).
= n(4 -1 +.5 -2)
= n(3 +.5 -2)
= n(3.5 -2)
= n(1.5)
= 1.5n
_____
Of course, you can do the addition in any convenient way. Some like to add all the positive and negative terms, then find the difference.
= n((4 +.5) -(1 +2)) = n(4.5 -3) = 1.5n
