Answer:

e = 3

Step-by-step explanation:

we need to do inverse operations

6 + 6 = 12

12 divided by 4 = 3

e = 3

Check:

4(3) - 6 = 6

Answer:

e = 3

Step-by-step explanation:

The first step in solving an equation that has a variable is to isolate it. The variable is the unknown number and it is usually what you are trying to find the value of (x is the sign most used to represent a variable).

In order to isolate the variable in the equation 4e - 6 = 6, add 6 to both sides of the = sign:

4e - 6 = 6

   + 6 = + 6

4e - 6 + 6 = 6 + 6

We add 6 because doing so will cancel out the -6, leaving only e.

4e = 12

Now, because the question is asking for the value of e and not 4e, the next step is to divide both sides by 4:

[tex]\frac{4e}{4}[/tex] = [tex]\frac{12}{4}[/tex]

After dividing, the equation is shown as e = 3, which would be your answer.

Answer:

sin (32) = 8.5/x

Step-by-step explanation:

hypotenuse is opposite the right angle (x)

Looking at the 32° angle , the number 8.5 is the opposite 32° angle

Trig ratios are    sin ∠ =  opposite/hypotenuse

                           cos ∠ = adjacent/ hypotenuse

                           Tan ∠ = opposite/ adjacent

Answer:

The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation.

The equation   − 2 (  x  +  3  )  =  − 2 x  −  6  does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation.

We have  − 2 (  x  +  3  )  means that each term inside the parenthesis should be multiplied with  − 2 , i.e.

− 2 (  x  +  3 )  =  − 2  ⋅  x  −  2  ⋅  (  +  3 )  =  − 2 x  −  6

Which is exactly what the right side says.

Any value of x will, therefore, fulfill this equation.

Answer:

1/9x + 1 = 7/3

-1              -1

1/9x = 1 1/3

divide by 1/9 on both sides to isolate x

Step-by-step explanation:

Answer:

x=1, y=3

Step-by-step explanation:

Rearrange equations 1 and 2 so that y is the subject

3x^2 = xy

Equation 1) y = 3x

Equation 2) 2y = 5x + 1

multiply the first equation by 2

2y = 6x

2y = 5x + 1

subtract the 2 equations from each other

2y - 2y = 6x - (5y +1)

0 = x - 1

x = 1

substitute x = 1 in the second equation

2y - 5(1) = 1

2y = 1 + 5

2y = 6

y = 3

Answer:

-3/4

Step-by-step explanation:

First, pick two coordinates.

(0,2) and (4,-1)

Then do the rise over run or y/x.

The y is 3 and the x is 4. That is 3/4.

Since the line is going down, it will be negative.

The answer is -3/4.

Using the mean formular, the sum of the four scores that are not the median would be 360.

Average or mean score = 450 / 5

Mean score = 90

Hence, median score = mean score = 90

The sum of the 4 scores that are not the median can be calculated thus :

Sum of the 4 scores = 450 - 90 = 360

Hence, the sum of the 4 scores that are not the median is 360.

-1 + 2x = 9

to get the solution

2x = 10

x = 5

2.

4 = 8 - x

x = 8 - 4 = 4

x/4 = 1

we could also write this

Answer:

65

Step-by-step explanation:

The triangle is isosceles. That means that the Vertical line meets the base at right angles because the peak angle is bisected. we are to assume. So the left angle is given as 25 degrees. The base and vertical angle meet and 90 degrees and so we solve for x, because every triangle has 180 degrees.

x + 25 + 90 = 180                  Combine the left.

x + 115 = 180                          Subtract 115 from both sides

x = 180 - 115

x = 65

[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]

Value of variable x is ~

[tex] \boxed{ \boxed{65 \degree}}[/tex]

According to given figure, the two sides of the triangle are equal. therefore it's opposite angles will be equal as well !

that is ~

Both angles measure 25° and the central (non - equal) Angle among them is 2x (2 times the Angle x)

Now, let's use Angle sum property of Triangle to find the value of x ~

[tex]5x + 2y = 9 \\ x + y = - 3 \\ \\ x + y = - 3 \\ = > x = - 3 - y \\ \\ 5x + 2y = 9 \\ 5( - 3 - y) + 2y = 9 \\ = > - 15 - 5y + 2y = 9 \\ = > - 15 - 3y = 9 \\ = > - 3y = 9 + 15 \\ = > - 3y = 24 \\ = > y = - 8 \\ \\ x + y = - 3 \\ = > x + ( - 8) = - 3 \\ = > x = - 3 + 8 \\ = > x = 5[/tex]
