Two-thirds of a number decreased by three is five equation form​
enot [183]

Answer:

2/3x - 3 = 5

Step-by-step explanation:

Let x be the number

2/3x - 3 = 5

Add 3 to each side

2/3x-3+3 = 5+3

2/3x = 8

Multiply each side by 3/2

3/2*2/3x = 8*3/2

x = 12

A game has a circular playing area in which you must hit a ball into a circular hole. The area of the playing area is 16ft2. The
Bad White [126]

Answer:

4.9\%

Step-by-step explanation:

we know that

To find out the probability of hitting a ball into the circular hole, divide the area of the hole by the area of the playing area

Let

x ----> the area of the hole

y ----> the area of the playing game

so

P=\frac{x}{y}

we have

y=16\ ft^2

<em>Find the area of the hole</em>

The area of the circle (hole) is equal to

A=\pi r^{2}

we have

r=1/2=0.5\ ft ----> the radius is half the diameter

assume

\pi =3.14

substitute

A=(3.14)(0.5)^{2}

A=0.785\ ft^2

<em>Find the probability</em>

P=\frac{x}{y}

we have

x=0.785\ ft^2

y=16\ ft^2

substitute

P=\frac{0.785}{16}

P=0.0491

Convert to percentage

0.0491*100=4.91\%

Round to the nearest tenth

4.9\%

If angle AEB has its vertex on the center of a circle and its endpoints on the circle, what is it?
Inessa [10]
1. Vertex E is the center of the circle, A and B are on the circle.

2. Any angle with these properties (i. E is center, AE and AB are radii) is called a central angle.

3. Check the picture. 

4. An important property of these angles is that the measure of the arc AB = m(AEB)

PLEASE I NEED HELP! How do you find y?
myrzilka [38]

In this example, y is equal to 8.

In order to find this, first note that the two x value expressions create a straight line. That means when we add them together they will equal 180. this will give us a value for x.

x + 10 + 10x - 61 = 180

11x - 51 = 180

11x = 231

x = 21

Now that we have the value of x, we can do the same for the straight line created by the x + 10 angle and the 18y + 5 angle.

x + 10 + 18y + 5 = 180

(21) + 10 + 18y + 5 = 180

36 + 18y = 180

18y = 144

y = 8
