Find the value of x :)

Mathematics
2 answers:
Kisachek [45]2 years ago

Answer:

x=20

Step-by-step explanation:

Those add up to 180 degrees because a straight line is 180 degrees

Equation

2x + 70 + 3x + 10 = 180

Add liked terms

2x+3x=5x

5x+80=180

5x+80-80=180-80

Divide both sides by 5

5x=100

x=20

hope this helps and good luck! <3

Answer:

x = 20

Step-by-step explanation:

→ Remember how many degrees are on a straight line

180°

→ Set up an equation

2x + 70 + 3x + 10 = 180

→ Simplify

5x + 80 = 180

→ Minus 80 from both sides

5x = 100

→ Divide both sides by 5

x = 20

You are getting ready for a family vacation. you decide to download as many movies as possible before leaving for the road trip.
PilotLPTM [1.2K]
Here is the solution for the given problem above.
Given: 1 2/5 hour = time it takes to download a movie
            5 1/4 hours = total hours for the download
            ? = number of movies downloaded
First, we need to simplify 1 and 2/5 hour, which is 1.4 hour, and 5 1/4 is 5.25 hours. Next, to get the number of movies downloaded, we divide 5.25 by 1.4 and the result is 3.75. Round this off to a whole number and we  get 4. Approximately, you were able to download 4 MOVIES. Hope this helps.

Suppose the average yearly salary of an individual whose final degree is a​ master's is ​$46 thousand less than twice that of an
seraphim [82]

Answer:

The average sallary of a Master's is 60 thousand and of a Bachellor's is 53 thousand.

Step-by-step explanation:

In order to solve this problem we first need to attribute variables to the unkown quantities. We will call the average salary of Master's "x" and the average salary of a Bachellor's "y". The first information the problem gives us is:

x = 2*y - 46

The second one is:

x + y = 113

We now have two equations and two variables, so we can solve the system. To do that we will use the value for x from the first equation on the second one. We have:

2*y - 46 + y = 113

3*y = 113 + 46

3*y = 159

y = 159/3 = 53

x = 2*(53) - 46 = 60

The average sallary of a Master's is 60 thousand and of a Bachellor's is 53 thousand.

Galileo wanted to release a wooden ball and an iron ball from a height of 100 meters and measure the duration of their fall. He
ICE Princess25 [194]
For this case what you have is the same as a rectangle triangle where you have as data the degree of inclination of the hypotenuse with respect to the base and the height of the triangle.
 We have to find the value of the hypotenuse.
 For this we use the following trigonometric relationship:
 senx = C.O / h
 Where
 x: angle
 C.O: opposite leg
 h: hypotenuse.
 Substituting the values we have:
 sen (12) = 100 / h
 We cleared h:
 h = 100 / sin (12)
 h = 480.97 m
 Answer: 
 Galileo should walk 480.97 m up the inclined plane
