M(4, 2) is the midpoint of rs. the coordinates of s are (6, 1). what are the coordinates of r?

(2, 3)

Step-by-step explanation:

There is an easy way to solve this.

Set it up like this, where one end point is on top of the midpoint.

To get from 6 to 4, you subtract 2. So subtract 2 from 4 (that's where the x coordinate comes from). To get from 1 to 2, you add 1. So add 1 to 2 (that's where the y coordinate comes from)

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
