Answers

Answer 1

Answer:

Step-by-step explanation:

Since they are vertical angles, they are equal to each other

3x=80-x

solve

4x=80

x=20

Answer 2

Answer:

x = 20

Step-by-step explanation:

==> 3x = 80 - x

=>Pass x to the other side the - sign into to +

==> 3x + x = 80

==> 4x = 80

==>[tex]x = \frac{80}{4} [/tex]

==> 80 ÷ 4

==> x = 20

Answers

Answers:ST = 23RU = 8SV = 5SU = 10

====================================================

Explanation:

Focus on triangles SVT and UVT.

They are congruent triangles due to the fact that SV = VU and VT = VT. From there we can use the LL (leg leg) theorem for right triangles to prove them congruent.

Since the triangles are the same, just mirrored, this means ST = UT = 23.

-----------------------

Following similar reasoning as the previous section, we can prove triangle RVU = triangle RVS.

Therefore, RS = RU = 8

-----------------------

SV = VU = 5 because RT bisects SU.

Bisect means to cut in half. The two smaller pieces are equal.

-----------------------

SU = SV + VU = 5+5 = 10

Refer to the segment addition postulate.

Answer:

ST=23

RU=8

SV=5

SU=10

Step-by-step explanation:

RT bisects the whole quadrilateral, so a line on one side will be the same length as the line on the opposite side of RT. So:

1. ST=UT, UT=23, so ST=23

2. RU=RS, RS=8, so RU=8

3. SV=VU, VU=5, so SV=5

4. SU=2*SV, 5*2=10, so SU=10

If you still have no clue, just imagine the points R, S, T, and the lines connecting them (this will make a triangle). Then reflect the triangle across line RT, and name the new S point U (the new triangle still has the same line measures) . Make a line from S to U and make a point V from where RT and SU meet. This will make the figure in the picture.

Step-by-step explanation:

Given;°C = 10°°F = 9/5C + 32

Now, Substitute C = 10

°F = 9/5C + 32

°F = 9/5(10) + 32

°F = 9 × 2 + 32

°F = 18 + 32

Analysis of graph :-

We have given one graph which is plot between distance and time. where time is in minutes and distance is in seconds.

According to the graph

For the first 5 minute ( O to A) , The distance is continously increasing 2m / per minute . For the 5 minute that is from 5 minute to 13 minute ( A to B) both marellize and her dog wally moving with the constant speed .For next 3 minutes that is from 10 minutes to 13 minutes ( B to C) , The distance is continously decreasing with time .For next 3 minutes that is from 13 to 16 minutes ( C to D) , Again they moved with constant speed .For next 6 minute that is from 16 to 21 minutes ( D to E) . Again, There distance is increasing with time .Again For next 4 minutes that is 21 to 25 minutes , they are moving with constant velocity .

Let's Begin :-

1) Between O and A

The marellize and wally when moving between O to A , The distance is constantly increasing with time. The graph is Straight line

2) Between A and B

The marellize and wally when moving between A to B, The distance remains the same with time that is they moving with constant speed. The graph is constant or steady

3) Between B to C

The marellize and wally when moving between B to C, The distance is constantly decreasing with time .The graph is straight line but it follows decreasing function .

4) For covering the First 6 km ,

According to the graph,

For covering first 6 km, They took 3 minutes.

5) No, Marellize and wally walk does not from where they have started.

According to the graph

It is end at 5 m instead of 0m .

The line between O and A is a straight line graph while A and B is a constant graph.

What is a graph?

A graph simply means a pictorial representation of information or data that's given.

In this case, O and A is a straight line graph while A and B is a constant graph. A straight line graph illustrates a linear relationship between between the x and y values.

Nine friends want to play a game. They must divide into three teams, with three people on each team. In how many ways can they do it?

Answers

Step-by-step explanation:

1.they should divide each person into 3 teams

Answer: 280

Step-by-step explanation: So you have 9 people. One out of those 9 people could go in any of the spots for participants. You could start off with 9*8*7 because you want to work your way down and it doesn't matter which order but just the number of people in each group. 9*8*7 is one group, 6*5*4 is the second group and 3*2*1 is the third group. Now, you want to take each of those equations and divide them by 3!. You do this because there are 3 teams and 9 people are being distributed between them.

9*8*7                        6*5*4                            3*2*1

--------     = 84         -----------     =20 and      -----------  =1

 3!                              3!                                   3!

Now that you have 84, 20 and 1, you multiply them and once again divide the product by 3! or cancel. You will get 14*20*1 =280

Solve the system of equations 4x + 3y = -25

7x - 3y = -52

Answers

Answer:

x = -7

y = 1

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable x

[2] 7x = 3y - 52

[2] x = 3y/7 - 52/7

// Plug this in for variable x in equation [1]

[1] 4•(3y/7-52/7) + 3y = -25

[1] 33y/7 = 33/7

[1] 33y = 33

// Solve equation [1] for the variable y

[1] 33y = 33

[1] y = 1

// By now we know this much :

x = 3y/7-52/7

y = 1

// Use the y value to solve for x

x = (3/7)(1)-52/7 = -7

Solution :

{x,y} = {-7,1}

find the value of x

Answers

Answer:

x= 11

Step-by-step explanation:

=> 8x+5x+37 = 180° { angle sum property }

=> 13x +37 = 180°

=> 13x = 180-37

=> 13x = 143

=> x = 143/13

=> x= 11

The required value of x in the given triangle is 11, for the triangle

The sum of angles 8x, 5x, and 37 degrees is equal to 180 degrees (using the angle sum property).


Adding 8x and 5x together gives 13x, so the equation becomes :
13x + 37 = 180 degrees.

Subtracting 37 from both sides of the equation gives:
13x = 180 - 37.

Simplifying the right side gives:
13x = 143.

To solve for x, we divide both sides of the equation by 13, resulting in:
x = 143/13.

Finally, simplifying the fraction gives:
x = 11.

Thus, the required value of x in the given triangle is 11, for the triangle.
