Rob brought a hat and 3 shirts for 35$. Dan brought 2 hats and a shirt for 20$. Which system of equations can be used to find s , the cost of one shirt and h , the cost of one hat

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
