Answer:
Hi
Step-by-step explanation:
The first one is equilateral triangle. The second answer is 85.
32+63+x = 180
x= 180 - (32+63)
x = 180 - 95
x = 85

2x+1=5x-8 Solving Equations with Many or No Solutions
Hello!
[tex]\large\boxed{x = 3}[/tex]
2x + 1 = 5x - 8
Solve by subtracting both sides by 2x:
2x - 2x + 1 = 5x - 2x - 8
1 = 3x - 8
Add 8 to both sides:
1 + 8 = 3x - 8 + 8
9 = 3x
Divide both sides by 3:
9/3 = 3x/3
x = 3
Answer:
x = 3
Step-by-step explanation:
1. Write the equation
2x + 1 + 5x - 8
2. Add 8 on both sides
2x + 9 = 5x
3. Get the variables together
9 = 3x
4. Solve for x and divide both sides by 3
x = 3

Answer:

equations below
Step-by-step explanation:
Order of operations is: PEMDAS = parentheses, exponents, multiplication, division, addition, subtraction
1. 5 x (20/4)
normally we multiply before we divide, but in this case, the division is in parentheses, so we start there
= 5 x 5
then multiply
= 25

2. The lovely land of exponents
6^2 (the only way I can type 6 squared, or 6 to the power of 2, where the 2 is up as a superscript)
6^2 - 2 x 6
PEMDAS has us do the exponents before multiplication or subtraction:
6^2 = 6 x 6 = 36
= 36 - 2 x 6
then multiply:
= 36 - 12
then subtract:
= 24

Solve for angle x please help fast
Answer:
X=18
Step-by-step explanation:
you can find what the missing angle is by subtracting 92 from 180 since its a straight line. After putting in the missing angle you can easily solve for 2X which is 36 and then divide by 2 and get 18.
Answer:
x = 23
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
92° is an exterior angle of the triangle, then
2x + 46 = 92 ( subtract 46 from both sides )
2x = 46 ( divide both sides by 2 )
x = 23

In the figure below, DF is a straight line. What is the degree measure of <FEG?
Answer:
c. 56 degrees
Step-by-step explanation:
angle FEG and angle DEG add up to 180.
2x-6+3x-31=180
x=31
2(31)-6=56
The measure of angle ∠ FEG is,
∠ FEG = 56°
We have to given that,
Angles are defined as,
∠ FEG = (2x - 6)°
∠ DEG = (3x + 31)°
Here, Angles FEG and angle DEG are linear pair.
Hence, angle FEG and angle DEG add up to 180.
2x - 6 + 3x + 31 = 180
5x + 25 = 180
5x = 180 - 25
5x = 155
x = 155 / 5
x = 31
Therefore, The measure of angle ∠ FEG is,
∠ FEG = (2x - 6)°
∠ FEG = (2 × 31 - 6)°
∠ FEG = (62 - 6)°
∠ FEG = 56°

Answer:
y = [tex]-\frac{1}{3}[/tex]
[tex]2\frac{2}{3}=x[/tex]
Step-by-step explanation:
To solve a system of equations, solve one or both of the equations for the same variable. Then multiply one of the equations such that the coefficients of one variable are the additive inverse of the variable in the other equation. After doing so, add the two equations, then solve for the other variable using inverse operations. Finally, substitute the value of the other variable into one of the original equations in the system and solve for the unknown variable.
2x + y = 3
y = x - 2
First, manipulate the first equation such that the equation is solved for (y), this can be done using inverse operations,
y = 3 - 2x
y = x - 2
Now multiply the second equation by (2) so that the (x) coefficients are additive inverses of each other,
y = 3 - 2x
2y = 2x - 4
Add the equations,
3y = -1
Inverse operations,
3y = -1
/3 /3
y = [tex]-\frac{1}{3}[/tex]
Now back solve, substitute the value of (y) into the equation and solve for (x),
[tex]y=x-3\\[/tex]
Substitute,
