21/12 in simplest form would be 7/4 which you divide by 3
Turning 7/4 into a mixed number would be 1 3/4

The answer would be 7/4 because you would just divide both the 21 and 12 by 3

The coordinates of midpoint M and endpoint Q of a segment are M(–7, 8) and Q(–19, 30). Find the coordinates of the other endpoin
Margaret [11]

Answer:

Step-by-step explanation:

Use the midpoint formula to solve:

M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

We know the midpoint and one set of coordinates, so filling those in:

(-7,8)=(\frac{x+(-19)}{2},\frac{y+30}{2})

Since the -7 is the x coordinate of the midpoint, we set the x part of the equation equal to -7 and solve for x, and then do the same for y. The 2 equations are:

-7=\frac{x-19}{2}  and  8=\frac{y+30}{2}  We solve each one of these to get the x and y coordinates of the other endpoint. In both cases, multiply both sides of the equations by 2 and then solve by either adding or subtracting.

-14 = x - 19 so

5 = x

16 = y + 30 so

-14 = y

The coordinates of the other endpoint are (5, -14)

Simplify.
Kazeer [188]
(1/2)^2 = 1/4
2-2/3 = 6/3 - 2/3 = 4/3

OK so:
(1/2)^2 - 6(2-2/3) = 1/4 - 6(4/3)
= 1/4 - 8
= 1/4 - 32/4
= -31/4
