Solve the equation using the distributive property 25-(3x+5)=2(x+8)+x <br><br> Solve for X

Help, need to find value of x and explain how I did it (the method used)

garri49 [273]

Answer:

X = 40 degree

Step-by-step explanation:

First I would name the points whatever you do always name the points it really helps

So,

75 = a

50 = b

The middle point will be o

85 = c

X = d

Ok so,

Angle aob = y

Angle cod = z

Now,

75+50+y=180 (angle sum property)

y=180-125

y=55

Angle y = z (vertically opposite angles)

55+85+x=180 ( angle sum property )

x=180-140

Therefore x=40 degree

In higher classes you will be able to do this in your mind itself without calculation all you need is practice.

what are the slope, X-intercept, and Y-intercept of the line represented by the equation? 5y = 10 - 15

abruzzese [7]

<span>5y = 10x - 15
y = -5x - 3
so slope = -5

x - intercept when y = 0
</span> -5x - 3 = 0
-5x = 3
x = -3/5
(-3/5, 0)
y - intercept when x = 0 then y = -3 (0,-3)

answer
slope = -5
x-intercept (-3/5, 0)
y-intercept (0, -3)

Your company is considering offering 900 employees the opportunity to transfer to its new headquarters in Ottawa and, as personn

Tresset [83]

Answer:

a) $P(100M) = \frac{100C100*1100C800}{1200C900}$

b) $P(1M) = \frac{100C1*1199C899}{1200C900}$

Step-by-step explanation:

Extract information from question:

Manager = M = 100

Factory Workers = FW = 200

Miscellaneous Staff = MS = 900

Total Workers = 1200

Moving Workers = 900

'Combinations' are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations the formula below is used:

$nCr=\frac{n!}{r!(n-r)!}$
