Question

Select all the expressions whichrepresent the total number of bookread by Joel, Lucas and Erica.x + (2x + 3) + (5 - 4x)6x + 87x+27X-2x + (2x + 3) + (4x - 5)

Answer 1

Given:

Joel read x books

Lucas read 3 more than twice the number of books Joel read

So,

Lucas read 2x + 3

Erica read 5 less than four times the number of books Joel read

So,

Erica read 4x - 5

So, the total number of books read by Joel , Lucas and Erica :

x + (2x + 3) + (4x - 5)

= 7x - 2

So, the correct options are:

$\begin{gathered} 7x-2 \\ x+(2x+3)+(4x-5) \end{gathered}$
