Answer:

YZ =  12, ML = 11

Step-by-step explanation:

The median is half the sum of the parallel bases, that is

YZ = \frac{KN+LM}{2}

4x - 16 = \frac{13+2x-3}{2} ( multiply both sides by 2 to clear the fraction )

8x - 32 = 10 + 2x ( subtract 2x from both sides )

6x - 32 = 10 ( add 32 to both sides )

6x = 42 ( divide both sides by 6 )

x = 7

Then

YZ = 4x - 16 = 4(7) - 16 = 28 - 16 = 12

ML = 2x - 3 = 2(7) - 3 = 14 - 3 = 11

Answer:

The bottom is  11

The median is  12

Step-by-step explanation:

The median is the average of the top and bottom

(13+ 2x-3) /2 = 4x-16

Combine like terms

(10+2x)/2 = 4x-16

Divide by 2

5+x = 4x-16

Subtract x from each side

5+x-x = 4x-16-x

5 = 3x-16

Add 16 to each side

5+16 = 3x-16+16

21 = 3x

Divide by 3

21/3 = 3x/3

7 =x

The bottom is 2x-3 = 2*7-3 = 14-3 = 11

The median is 4x-16 = 4*7-16 = 28 -16 = 12

Geometry// question #8
MAVERICK [17]

Answer:

see explanation

Step-by-step explanation:

The translation rule

(x, y ) → (x + 3, y - 2 )

Means add 3 to the original x- coordinate and subtract 2 from the original y- coordinate, thus

A(- 4, 1 ) → A'(- 4 + 3, 1 - 2 ) → A'(- 1, - 1 )

B(1, 1 ) → B'(1 + 3, 1 - 2 ) → B'(4, - 1 )

C(1, - 2 ) → C'(1 + 3, - 2 - 2 ) → C'(4, - 4 )

D(- 4, - 2 ) → D'(- 4 + 3, - 2 - 2 ) → D'(- 1, - 4 )

Write 29/9 as a mixed number.
natka813 [3]
To find 29/9 as a mixed number you need to find out how many times does 9 fit in 29

9
18
27
36

We see that it fits 3 time 3 is your whole #
We also see that 29 - 27 = 3 so you write like this:

3 3/9

The denominator of the original fraction does change
