Question 947328: 1) Michael travels x miles to get to work each day. His coworker, Rachel, travels 15 more miles than he does. Write an expression, in terms of x, for the distance Rachel travels.
2)Their other coworker, David, travels 3 miles as many miles as Rachel to get to work. Write an expression, in terms of x, for how far David travels.
Answer by Lyd999(3)   (Show Source):
You can put this solution on YOUR website! 1.) Michael travels x miles, so Michael =x Rachel travels 15 more than Michael so her equation would be R=m+15
You have to add 15 miles to Michael (x) to get Rachel's.
2.)
We still have the same equations for Michael and Rachel.
Michael = X
And
Rachel = (X + 15)
(I use the parenthesis because it is easier to distinguish who is who)
If Daniel travels three times as many miles as Rachel, then his equation would be
3(X + 15)
I hope this helps!
This is because Rachel is the amount in the parenthesis and Daniel travels three times as many miles.
