First  Draw Picture ====>   <JKL

Draw  Ray  =====>   KM


Equation:

===>  m<JKM    +     m<MKL      =     m<JKL

Solve:

9x     -     10     +    83      =     127

Steps:

9x     -     10     +    83      =     127

Add/Subtract the Numbers:

-10    +   83      =     73

9x    +   73    =    127

Subtract   73  from both sides:

9x     +     73    -    73       =     127     -     73

Simplify:

9x      =     54

Divide both sides by  9:

9x/9      =       54/9

x          =          6

Answer   =======>  The Value of  ======>       x            =        6



Hope that helps!!!!                                         : )

Find the following sums ( for letter C)
anygoal [31]

Each number in the sum is even, so we can remove a factor of 2.

2 + 4 + 6 + 8 + ... + 78 + 80 = 2 (1 + 2 + 3 + 4 + ... + 39 + 40)

Use whatever technique you used in (a) and (b) to compute the sum

1 + 2 + 3 + 4 + ... + 39 + 40

With Gauss's method, for instance, we have

S = 1 + 2 + 3 + ... + 38 + 39 + 40

S = 40 + 39 + 38 + ... + 3 + 2 + 1

2S = (1 + 40) + (2 + 39) + ... + (39 + 2) + (40 + 1) = 40×41

S = 20×21 = 420

Then the sum you want is 2×420 = 840.

!PLEASE HELP!<br>Solve for MN. <br><br>A) 21 <br><br>B)9 <br><br>C)6 <br><br>D)4
Oksanka [162]

The measure of MN from the diagram is 6

<h3>Similarity theorem of triangles</h3>

From the given triangle, the expression below is true;

ML/LK = MN/NO

Given the following parameters

ML = 4

LK = 10

NO= 15

Substitute the given parameters into the formula

4/10 = MN/15

Cross multiply

10MN = 4 * 15

10MN = 60

MN = 6

Hence the measure of MN from the diagram is 6
