ValentinkaMS [17]3 years ago
8 0

Look at the picture.

[tex\alpha+\beta=180^o[/tex] - supplementary angles

Therefore we hve the equation:

(14x-6)+(15+5x)=180\\\\(14x+5x)+(-6+15)=180\\\\19x+9=180\qquad\text{subtract 9 from both sides}\\\\19x=171\qquad\text{divide both sides by 19}\\\\\boxed{x=9}

If LM = 4x, MN = x + 1, and LN = 6, what is MN?
Ilia_Sergeevich [38]

The value of the MN is 2 according to the assumption on the number line.

According to the statement

We have to find that the value of the MN with the help of the value of the x.

So, For this purpose, we know that the

A number line is a horizontal line that has equally spread number increments.

Now,

Assuming that L, M, and N are points on a number line with L < M < N,

According to the assumption, the equation become

4x + x+1 = 6  

5x +1 =6

5x =5

x = 1.        

Now, the value of the MN become:

MN = x + 1

MN = 1 + 1

MN = 2.

So, The value of the MN is 2 according to the assumption on the number line.

What is the slope of the line that passes through (8,4) and (6,7)?
bija089 [108]
slope=\frac{y_2-y_1}{x_2-x_1}\\\\ &#10;(x_1,y_1)=(8,4)\\ &#10;(x_2,y_2)=(6,7)\\\\&#10; slope=\frac{7-4}{6-8}=\frac{3}{-2}=-\frac{3}{2}\\\\&#10;Slope\ is\ equal\ to\ -\frac{3}{2}.&#10;

25% of what number is 9
Alexeev081 [22]
Keep in mind the the word "percent" translates to "for each 100." 25% can be read as "25 for each 100," which has the fractional representation \frac{25}{100} and the decimal representation 0.25. All of these representations are just different ways of writing the same value.

Note too that the fraction \frac{25}{100} can be reduced to \frac{1}{4}, so what the question is really asking is: 1/4 of what number is 9?

Well, if we know that 1/4 of the number is 9, we can easily find how large the whole number is by finding all 4/4 of it (the <em>whole</em> number)<em /><em />, or 4 x 9, which multiplies out to 36.
