Answer:
[tex]5(r-1)[/tex]
Step-by-step explanation:
Given:
Maria collected r rocks.
Javier collected twice as many rocks as Maria.
Pablo collected 5 less than Javier.
Question asked:
What equation is equivalent to number or rocks collected ?
Solution:
Maria collected number of rocks = [tex]r[/tex]
Javier collected number of rocks = [tex]2r[/tex]
Pablo collected number of rocks = [tex]2r-5[/tex]
The equation is equivalent to number or rocks collected will be:-
[tex]=r+2r+2r-5\\ \\= 5r-5\\ \\ Taking\ 5\ as\ common\\ \\ =5(r-1)[/tex]
Thus, the equation will be [tex]5(r-1)[/tex]
