Angle Sum Theorem (C)

This one allows you to add the angles together to get 180 degrees always, which is why you only need to prove that two corresponding angles of a triangle are congruent.<span />

A)
$18=1\cdot12+6$
$12=2\cdot6+0$
$\implies\mathrm{gcd}(12,18)=6$

b)
$201=1\cdot111+90$
$111=1\cdot90+21$
$90=4\cdot21+6$
$21=3\cdot6+3$
$6=2\cdot3+0$
$\implies\mathrm{gcd}(111,201)=3$

c)
$1331=1\cdot1001+330$
$1001=3\cdot330+11$
$330=30\cdot11+0$
$\implies\mathrm{gcd}(1001,1331)=11$

d)
$54321=4\cdot12345+4941$
$12345=2\cdot4941+2463$
$4941=2\cdot2463+15$
$2463=164\cdot15+3$
$15=5\cdot3+0$
$\implies\mathrm{gcd}(12345,54321)=3$

e)
$5040=5\cdot1000+40$
$1000=25\cdot40+0$
$\implies\mathrm{gcd}(1000,5040)=40$

f)
$9888=1\cdot6060+3828$
$6060=1\cdot3828+2232$
$3828=1\cdot2232+1596$
$2232=1\cdot1596+636$
$1596=2\cdot636+324$
$636=1\cdot324+312$
$324=1\cdot312+12$
$312=26\cdot12+0$
$\implies\mathrm{gcd}(9888,6060)=12$

Find the solution of this system of equations. Separate the x- and y-values with a comma. x - 4y = 12 and x - y = 0

Elenna [48]

Use elimination and subtitution method to solve the problem.
First, eliminate x and you'll find the value of y
x - 4y = 12
x - y = 0
--------------- - (substract)
-3y = 12
y = 12/-3
y = -4

Second, subtitute -4 as y and you'll find the value of x
x - y = 0
x- (-4) = 0
x + 4 = 0
x = -4

The solution
x,y = -4,-4

You randomly draw a marble out of a bag containing 4 green marbles, 6 blue marbles, 8 yellow marbles, and 2 red marbles. Find th

shutvik [7]

Answer:

<h3>The probability is </h3><h3> $\frac{3}{5}$ </h3>

Step-by-step explanation:

Green marbles = 4

Blue marbles = 6

Yellow marbles = 8

Red marbles = 2

$4 + 6 + 8 + 2 = 20 \: marbles$

The probability of drawing marble not yellow:

$4 + 6 + 2 = 12 \\ \frac{12}{20} = \frac{3}{5}$

Brainliest please.
