Answer:

x = 6

y = -6

Step-by-step explanation:

x + y = 0 (Multiply by -1)

x + 9y= -48

-x - y = 0

x + 9y= -48

8y = -48

y = -6

x + y = 0

x - 6 = 0

x = 6

<h2>54 units²</h2><h2 />

This is a compound shape. You can split it into x shapes. See Attachment

  • Rectangle - Red

Area of a Rectangle = L × B

L = 7

B = 6

7 × 6 = 42

<h3>42 units²</h3>

  • Triangle - Orange

Area of a Triangle = 1/2BH

B = 6

H = 1

1/2 × 6 × 1 = 3

<h3>3 units²</h3>
  • Triangle - Green

Area of a Triangle = 1/2BH

B = 3

H = 2

1/2 × 3 × 2 = 3

<h3>3 units²</h3>

  • Triangle - Blue

Area of a Triangle = 1/2BH

B = 2

H = 6

1/2 × 2 × 6 = 6

<h3>6 units²</h3><h3 /><h3>42 + 6 + 3 + 3 = 54</h3>

omeli [17]

Answer:

Step-by-step explanation:

First order from smallest to largest.

70.8, 71.9, 72.1, 82.4, 85.3, 98.1.

Median is the middle number/s.

72.1+82.4/2 so The median is 77.25

Range is the largest number minus the smallest number.

85.3-70.8=14.5

Mode is the most repeated number.

Since there are no repeated numbers there is no mode.

Second question:

Again rearrage: 6, 9, 11, 14, 17

In order to make the median 10 you would have to add another 9 becasue

11+9/2 = 10

Third: remove 6 to make 12 the middle number

Fourth: add all numbers 90+x/6=20 so x has to be 30
