Aldo is mailing packages m. each small package cost him $2.40 to send. each large package cost him $3.80. how much will it cost him to send 4 small packages and 1 large package?

$13.40

Step-by-step explanation:

This is solved by multiplying 2.40 4 times, then adding 3.80, which gets you 13.40, hope this was helpful!

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

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.
