Question

Evaluate the expression b= 3/10c= 2/153c-bwrite in the simplest form

Answer 1

-7/10

Explanation:

3 × -2 / 15 - 3/10

-12/30 - 9/30

-21/30

-7/10

Answer 2

`\begin{gathered} b=(3)/(10) \\ c=-(2)/(15) \end{gathered}`

Evaluate those values into the expression:

`\begin{gathered} 3c-b \\ so\colon \\ 3(-(2)/(15))-(3)/(10) \\ -(6)/(15)-(3)/(10)=(-60-45)/(150)=-(105)/(150)=-(7)/(10) \\ \end{gathered}`

Answer:

`-(7)/(10)`
