1.which of the following is not true for adding mixed numbers?

A.the denominators of the fractions must be the same in order to add them.

B.you can add mixed numbers by changing them into improper fractions or by using a number line.

C.the sum of the mixed numbers written as an improper fraction is in simplest form.

D.the sum of the mixed numbers must be written in simplest form

The answer is C

how is that middle school

step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
