solve
4x=80
x=20
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

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.

Solve for F if C = 10°.
F = C + 32
Answer:
The answer is 50°
Step-by-step explanation:
Given;°C = 10°°F = 9/5C + 32Now, Substitute C = 10
°F = 9/5C + 32
°F = 9/5(10) + 32
°F = 9 × 2 + 32
°F = 18 + 32
°F = 50
Thus, The value of °F is 50°

Answer:
15 ways
Step-by-step explanation:
We need 2 people from a group of 6.
Pick a random person from the 6, then group them with another person. We have 5 ways to do so.
Now, we will pick a person to group with the person who got grouped with the first person, except the first person themself. We have 4 ways to do so
Keep repeating, we will have 5 + 4 + 3 + 2 + 1 = 15 ways to choose 2 people out of 6.

the figure shows a circle within a square. Find the circumference of the circle let π = 3.14.
The side of the square = 16 in
When a circle is inscribed in a square, the length of each side of the square is equal to the diameter of the circle.
So, the diameter of the circle is equal to 16 in => radius = 8 in
Circumference = 2πr = 2π8 = 16π = 50.24
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?
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
Hope it helps!

Solve the system of equations 4x + 3y = -25
7x - 3y = -52
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
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.
