Mathematics
1 answer:
castortr0y [4]3 years ago
6 0

Answer:

r = 20

Step-by-step explanation:

-4 = r/20 - 5

-4 + 5 = r/20 - 5 + 5

1 = r/20

1 * 20 = r/20 * 20

r = 20

Answer:

x = 14

Step-by-step explanation:

The 2 given angles are vertical angles abd are congruent, so

4x - 22 = x + 20 ( subtract x from both sides )

3x - 22 = 20 ( add 22 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Then

x + 20 = 14 + 20 = 34°

4x - 22 = 4(14) - 22 = 56 - 22 = 34°

Solve for x: the quantity of x plus 16 all over 3 = 3x (1 point) x = −7 x = −13 x = 8 x = 2
Hatshy [7]
<h2>The required value of x is equal to 2.</h2>

Step-by-step explanation:

We have,

\dfrac{x+16}{3}=3x

To find, the value of x in the given equation = ?

∴ \dfrac{x+16}{3}=3x

By crossmultiplication, we get

3(3x) = x + 16

⇒ 9x = x + 16

⇒  9x - x = 16

⇒  8x = 16

⇒  x = \dfrac{16}{8}

⇒  x = 2

∴ The value of x = 2

Thus, the required value of x is equal to 2.

Find the measure of &lt;_B (show work if possible)
Mandarinka [93]

Answer: <b is 59.3 degrees

Step-by-step explanation:

Triangles have total of 180 degrees

The bottom two points are both 4y

To solve: 4y+4y+(3y+14)=180

11y+14=180

-14

11y=166

Divide by 11

Y=15.1

So plug that in for y

3(15.1)+14=B

59.3

Hope this helped

Here’s a graph of a linear function write the equation that describes that function
posledela

Answer:

The answer is y = 4x - 1

Step-by-step explanation:

First find two points on the line.

I will be using (-1, -5) & (1, 3).

Using the formula for slope, substitute in the values and solve:

y2-y1/x2-x1(This is the formula)

3--5/1--1(When using this formula, if y1 or x1 are negative, make them positive.)

3+5/1+1 or 8/2; which simplifies into 4/1.

So, the slope is 4/1.

Now we use point-slope form:

y - y1 = m(x-x1)

1. Substitute in the values.

y--5 = 4/1(x--1)

2. Simplify and distribute.

y + 5 = 4/1x + 4

3. Subtract 5 from both sides.

y = 4/1x - 1

4. Simplify.

y = 4x - 1
