Answer:
1. 25
2. 24
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

Answer:
angle bcf = 113 degrees :)
Step-by-step explanation:
angle bca and angle dcf equal 134 in total
360-134= 226
226/2=113
Answer:
113
Step-by-step explanation:
Remark
<BCA and <BCF are on the same straight line. That means when added, they equal 180 degrees.
Givens
<BCA = 67
Two Parallel lines
1 Transversal
Solution
<BCA + < BCF = 180
67 + <BCF = 180
<BCF = 180 - 67
<BCF = 113
How many solutions can be found for the equation 5x + 3(x − 1) = 10x − x − 5? (4 points)
a
No Solution
b
One
c
Two
d
Infinitely many
Answer:
The correct option is b.
Step-by-step explanation:
To find the number of solutions, we need to solve the equation:
[tex] 5x + 3(x - 1) = 10x - x - 5 [/tex]
Let's group all the "x" on the equation.
[tex] 5x + 3x - 10x + x = 3 - 5 [/tex]
Now, let's solve for "x".
[tex] -x = -2 [/tex]
[tex] x = 2 [/tex]
Therefore, the equation has one solution. The correct option is b.

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,
[tex](-\frac{1}{3})=x-3[/tex]
+3
[tex]2\frac{2}{3}=x[/tex]

Uma loja de brinquedos tem uma vitrine com várias prateleiras contendo 21 bonecas, 18 carrinhos de brinquedo e 15 bonecos de ação. Cada prateleira tem 18 brinquedos e todas as prateleiras são usadas
Responder:
3
Explicação passo a passo:
Dado :
Total de brinquedos:
Bonecas = 21
Carros Roy = 18
Figuras de ação = 15
Número total de brinquedos = (21 + 18 + 15) = 54 brinquedos
Número de brinquedos por prateleira = 18
Número de prateleiras:
Número total de brinquedos / número de brinquedos por prateleira
Número de prateleiras = 54/18
Número de prateleiras = 3
3 prateleiras estão na vitrine
Write an equation of the perpendicular bisector of the segment with endpoints M(-3,4) and N(9,8).
Answer:
y= -3+15please mark in brain list2x+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

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°
