Answer: 26 :))

Step-by-step explanation: 20 + 2a = 8 + 6a flip terms than subtract 20 from both sides, simplify to 2a = 6a - 12, subtract 6a from both sides, simply and CLT and you have -4a = -12, divide both sides by -4 and you have 3 = a so plug it in to the equation and you have 26 = YZ

Answer:26

Step-by-step explanation:

20+2a=8+6a                                  8+18=26

    -2a     -2a

---------------------

   20=8+4a

  -8   -8

-------------------

12=4a                                        

12/4=4a/4    a=3

Which equation could have been used to create this function table? 1 2,3 6,4 8,5 10, 10 20 A. y = 5x B. y = x + 1 C. y = x + 2 D
levacccp [35]

Try the first table value and see what you get from the various choices. For x = 1, the answer choices give you

... A: y = 5×1 = 5

... B: y = 1 + 1 = 2

... C: y = 1 + 2 = 3

... D: y = 2×1 = 2


Both B and D give the correct value (2), so we need to try another table entry. For x = 3 (the second table entry), the answer choices give you

... B: y = 3 + 1 = 4

... D: y = 2×3 = 6


Only selection D gives you the correct value (6). The appropriate choice is

... D. y = 2x

Need help with Graphs. please help!!
kozerog [31]

The ratio of the area of the red rectangle to the blue rectangle in graph A is 3 : 5

<h3>Median weekly earnings</h3>

The median weekly earnings on the graphs are

  • High school diploma = $750
  • Bachelor's degree = $1250

Represent as a ratio

Ratio = $750 : $1250

Divide by 250

Ratio = 3 : 5

Hence, the ratio of the median weekly earnings is 3 : 5

<h3>The ratio of the area in graph A</h3>

In (a), we have:

Ratio = 3 : 5

The horizontal scale is given as:

Ratio = 1 unit : 1 grid mark

The rectangles in graph A have a width of 1 unit.

So, we have:

Ratio = 3 * 1: 5 * 1

Ratio = 3 : 5

Hence, the ratio of the area of the red rectangle to the blue rectangle in graph A is 3 : 5

<h3>The ratio of the area in graph B</h3>

Recall that:

Ratio = 3 : 5

Ratio = 1 unit : 1 grid mark

From the graph, we have the following widths:

Red = 3 units

Blue = 5 units

So, we have:

Ratio = 3 * 3 : 5 * 5

Simplify

Ratio = 9 : 25

Hence, the ratio of the area of the red rectangle to the blue rectangle in graph B is 9 : 25

<h3>The ratio of the volume in graph C</h3>

Recall that:

Ratio = 3 : 5

Ratio = 1 unit : 1 grid mark

From the graph, we have the following widths:

Red = 3 units

Blue = 5 units

Since the base are squares, we have:

Ratio = 3 * 3  * 3 : 5 * 5 * 5

Simplify

Ratio = 27 : 125

Hence, the ratio of the volume of the red cube to the blue cube in graph C is 27 : 125

<h3>The most misleading graph</h3>

The most misleading graph is graph B.

This is so because the blue rectangle and the red rectangle do not have the same width when plotted on the same scale
