What is the value of x?

Mathematics
1 answer:
Rufina [12.5K]3 years ago
6 0

Answer:

X=23

Step-by-step explanation:

You should know that a triangle =180 degrees

Add all your angles together and =180

66+2x+3+3x-4=180

add similar terms

5x+65=180

Move your 65 to the other side

5x=115

x=23

(Optional)

to check if your answer is right substitute your x and add all angles together you should get 180 degrees.

ILL MARK AS BRAINLIEST!! AND GIVE 10 POINTS!!! Are the following lines parallel, perpendicular, or neither?
Licemer1 [7]

Answer:

b perpendicular

Step-by-step explanation:

all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites

Line 1)      -7 -8 / -3 -2  X= 3X

Line 2)      -3 - 0 / 12 - 3  X = -1 / 3X

Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.

I will show you how to do the first one.....we are finding the GCF...the largest number that goes into each number (same for variables)

1.)  20yx , 80x³  ( factor each number and variable)

20  =  2, 4, 5, 10, 20
y    =  y
x     =  x
80  =  2, 4, 5, 8, 10, 16, 20, 40, 80
x³  =  x, x, x

what is the largest number that 20 and 80 have in common?    20...
how about the variables?    x

so, the Greatest Common Factor (GCF is 20x)

Consider the following. (Assume that the coins are distinguishable and that what is observed are the faces or numbers that face
Nataliya [291]

Answer:

a)  P(

b)  n=(HHH, HHT, HTH, HTT, THH, THT, TTH, TTT).

Step-by-step explanation:

From the question we are told that:

3 coin are tossed

Therefore

Sample space n=(HHH, HHT, HTH, HTT, THH, THT, TTH, TTT).

Generally the sets that correspond with the result of at most one tail is therefore given as follows

P(

Therefore

The result is at most one tail when

If the flotation costs are 2 percent of gross proceeds, and gross proceeds are $250,000, what is the dollar amount of flotation
alina1380 [7]

The dollar amount of the flotation costs by percent of gross proceeds is $5,000

We need to know about the percent theory first, percent is per 100. So when A is 1% of B it means that

A = 1/100 x B

From the question, we know that

The gross proceeds is given by = $250,000 and

the flotation cost is given by = 2% of gross proceeds.

We can write the flotation cost as

Flotation cost = 2/100 x $250,000

Flotation cost = 2/100 x $250,000

Flotation cost = $5,000

Hence, the dollar amount of the flotation costs is $5,000
