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]

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:

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

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:First one is equilateral triangle Second one is 85  

Step-by-step explanation:

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

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:

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.
