(8, 2) 

You can get this by using elimination. Multiply the bottom equation entirely by -5 and the x terms will cancel. You can then solve for the y value and use that to find the x.

I need to find the area of the shaded region, but I need detailed steps
olasank [31]
The shaded region is a parallelogram.

The formula for the area of any parallelogram is A=bh.

The base of the parallelogram is 2 meters long (given).

The height of the parallelogram is 9 meters (do not be fooled by the unnecessary information of 14 meters)
The height is 9 meters because the height has to be perpendicular to the base. Thus, the side length must be 9 meters.

Multiply them together.

2 \times 9 = 18

The area of the parallelogram is 18 square meters.

How to find the area of each of the shaded sectors and round to the nearest hundredth
Mazyrski [523]

Answer:

1-6 you need to write the JHI DEF where the radius center point is in the middle of each shape next to 1-6 some have 2 shapes so use 6 letters there.

Step-by-step explanation:

1. Area = 72 of 360 = 20% of 716.3 =  143.26inch*2 =JHI

2.Area =  19 of 360 = 68.4% of 69.4  = 47.46km^2 =DEF

3. Area = 92 of 360 = 25.56% of 153.9 = 39.33cm^2

4. Area = 226 of 360 = 64.57% of 706.9 = 456.45ft^2

5.  Area = 74 of 360 =  20.55% of 153.9 =31.63 inch^2

6. Area = 326 of 360 = 90.56% of 1452 -137.07 = 1314.93m^2

Given the figure below, find the values of x and z.<br> (10x - 65)<br> (9x - 49)
nexus9112 [7]
(10x - 65) degrees is equal to (9x - 49) degrees, therefore you can set them into an equation.

(10x - 65) = (9x - 49)

By subtracting 9x in both sides,

(10x - 9x) - 65 = (9x -9x) - 49

x - 65 = -49

By adding 65 in both sides,


x - 65 + 65= -49 + 65
x = 16


Next, to find the value of z, it’s important to know that the straight line has 180 degrees. Then you would substitute the x value you found into one of your equation and subtract it from 180.

10 (16) - 65 = 160 - 65 = 95

Now you know that (10x - 65) degrees is equal to 95 degrees,

180 - 95 = z = 85


Answer: x = 16
z = 85
