It's probably not right

**Step-by-step explanation:**

Simplifying

13x + 6y = 180

Solving

13x + 6y = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6y' to each side of the equation.

13x + 6y + -6y = 180 + -6y

Combine like terms: 6y + -6y = 0

13x + 0 = 180 + -6y

13x = 180 + -6y

Divide each side by '13'.

x = 13.84615385 + -0.4615384615y

Simplifying

x = 13.84615385 + -0.4615384615y

**Answer:**

**Step-by-step explanation:**

Try .83

8 + 3 = 11

8*3 = 24

.84> 1/2

n = 24.

7

What is the value n?

n = 18

On = 20

0 n=218

O n=23

**Answer:**

n = 20

**Step-by-step explanation:**

n + 1/5 n = 24

n + n/5 = 24

LCM = 5

5n/5 + n/5 = 24

( 5n + n )/5 = 24

5n + n = 5 x 24

6n = 120

n = 120 / 6

n = 20

Find the volume of a sphere with a diameter of 18.8 cm, . Use 3.14 for π. Round your answer to the nearest tenth.

869.3 cm3

1,956 cm3

1,109.8 cm3

3,477.4 cm3

**Answer:**

(c) 3,477.4 cm³

**Step-by-step explanation:**

The formula for the volume of a sphere is ...

V = 4/3πr³ . . . . where r is the radius

The radius is half the diameter, so is 18.8 cm/2 = 9.4 cm.

Using this value and the value for pi in the formula, we have ...

V = (4/3)(3.14)(9.4 cm)³ = (4/3)(3.14)(830.584 cm³) ≈ **3477.4 cm³**

I need help solving for Y

**Answer:**

y=24

**Step-by-step explanation:**

since the triangles are similar, their sides are all in proportion

meaning:

[tex] \frac{20}{15} = \frac{32}{y} [/tex]

simplify the fraction

[tex] \frac{4}{3} = \frac{32}{y} [/tex]

cross multiply once the fraction is simplified

[tex]96 = 4y[/tex]

y=24

**Answer:**

y = 24

**Step-by-step explanation:**

the first triangle 20 : x : 32

the 2nd triangle 15 : 21 : y

Solve the equation of two triangles by similarity

x = [tex]\frac{21 * 20}{15}[/tex] = 28

y = [tex]\frac{21 * 32}{28}[/tex] = 24

solve for x & y

plsssss, sorry.

**Answer:**

[tex]\huge\boxed{x=29;\ y=51}[/tex]

**Step-by-step explanation:**

This is Isosceles triangle (look at the picture).

We know:

All triangles have internal angles that add up to 180°

Therefore:

[tex](x-2)+(x-2)+(4x+10)=180[/tex]

combine like terms:

[tex](x+x+4x)+(-2-2+10)=180\\\\6x+6=180\qquad|\text{subtract 6 from both sides}\\\\6x=174\qquad|\text{divide both sides by 6}\\\\x=29[/tex]

(x - 2)° and 3y° are supplementary angle (Two Angles are Supplementary when they add up to 180°).

Therefore:

[tex]3y+(x-2)=180[/tex]

substitute x = 29 and solve for y:

[tex]3y+(29-2)=180\\\\3y+27=180\qquad|\text{subtract 27 from both sides}\\\\3y=153\qquad|\text{divide both sides by 3}\\\\y=51[/tex]

Can someone please help me with the graph above ?? please

Answer:

See image

Step-by-step explanation:

The third line of the directions that says

(x,y)->(x-5, y)

is telling you to look at each point and keep the y the same, but subtract 5 from the x. For example, point B which is given as the point (4,-1) will slide over 5 places to the left and keep the y the same to (-1,-1) see image

The whole shape will slide over to the left 5 places. (red)

Then, it says reflect over y=0. Which is a flip like a mirror image.(green) The final answer is the green figure.

If x + 2y = 15, what is the value of 3x + 6y/5

**Answer:**

I *think** **9** **is** the** best** answer*

**Answer:**

9 is the answer.

**Step-by-step explanation:**

Given:

x + 2y = 15We can tell that '3x + 6y' is basically '15 x 3' because the whole equation has been multiplied by three. Therefore, 3x + 6y must equal 45.

=> 3x + 6y = 45

But we need to divide 45 by 5 to get the solution because the 3x + 6y has also been divided by 5.

=> 45/5

=> 9

Therefore, 9 is the answer.
