Answer: 3\sqrt{13}

Step-by-step explanation:

\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

\sqrt{\left(-4-2\right)^2+\left(3-\left(-6\right)\right)^2}

=3\sqrt{13}

K (3x - 2) = 4 - 6x<br> Find the value of k
svlad2 [7]

Hello!

In this case, you are looking for a value of K so the left side of the equation is equal to the right.

The left side of the equation is K (3x - 2), and the right is 4 - 6x. To get the left side to equal the right, you can set K = -2. This is because of the <u>distributive property</u>: a number just outside of the parenthesis can distribute to everything in the parenthesis like so:

-2 (3x - 2) = (-2 * 3x) - (-2 * -2) = -6x + 4

Therefore, your answer is K = -2.

Hope this helps!

(Side note: a better way to do this would be to divide both sides by 3x - 2)

Answer:

Torrance spends 16$ on his brother

Step-by-step explanation:

You have 100$

So, we have

x (brother) + x (sister) + x (mother) = 100

But, since 10$ less will be spent on the sister than the brother, it becomes (x - 10) and twice + 6$ is spent on the mom, it also becomes (2x + 6)

Our equation then becomes

(x - 10) + x + (2x + 6) = 100

X will end up equaling 26. This is how much is spent on the sister.

(x - 10) will be substituted for (26 - 10), which equals 16.

I'm not sure if this is right so you might want to check with somebody (since I may be wrong) I hope this helps you understand how to basically do it though. <3

The ratios of measures of the angles in Triangle ABC is 4:13:19. Find the measures of each of the angles. Show all of your work/
Grace [21]

Answer:

20

65

95

Step-by-step explanation:

Remark

You have to use a constant to get the ratio so that it will produce angles that will add up to 180. Let that constant = x

Equation

4x + 13x + 19x = 180

Solution

Add the like terms on the left.

36x = 180                          

Divide both sides by 36

36x/36 = 180 /36

Combine

x = 5

Answer

4x =   20

13x =  65

<u>19x =  95</u>

Total = 180
