Question

Jaylin created the following expression:

2/5x −3/10 − x + 1 7/10x − 1/10
Jaylin created an equivalent expression using the following steps:

4/10x + (−1x) +1 7/10x + (−3/10) +(−1/10) 1 1/10x +−2/5
Is his final expression equivalent to the initial expression? Show how you know. If the two expressions are not equivalent, find Jaylin's mistake and correct it.

Answer 1

Answer:

1/10 and -2/5 are not in the original sentence

Step-by-step explanation:

2/5x=4/10x

(-1x)=-x

1 7/10x=1 7/10x

-1/10=(-1/10)

-3/10=(-3/10)

1 1/10 and -2/5 are not in the original sentence.
