Answer:

Option C

Option D

Step-by-step explanation:

We have to calculate each expression to find for which one is the solution is x=25.

A)

[tex] \frac{x + 6}{3} = 10 \\ x + 6 = 10 \: . \: 3 \\ x + 6 = 30 \\ x = 30 - 6 \\ x = 24[/tex]

B)

[tex]x - 8 = 32 \\ x = 32 + 8 \\ x= 40[/tex]

C)

[tex]6x - (15 + 4x) = 35 \\ 6x - 15 - 4x = 35 \\ 2x = 35 + 15 \\ 2x = 50 \\ x = \frac{50}{2} \\ x = 25[/tex]

D)

[tex] \frac{3x}{5} = 15 \\ 3x = 15 \: . \: 5 \\ 3x = 75 \\ x = \frac{75}{3} \\ x = 25[/tex]

E)

[tex]4(x - 18) = 12 \\ x - 18 = \frac{12}{4} \\ x - 18 = 3 \\ x = 3 + 18 \\ x = 21[/tex]

Answer:

She is correct.

Step-by-step explanation:

1/2 and 50% is the same thing

50%  is 1/2 of 100

2x^2 + 14x + 12 = 0

x^2 + 7x + 6 = 0

( x + 1 )( x + 6 ) = 0 ==》 x = - 1 Or x = - 6

Answer:

[tex]\large\boxed{\tt x = 444.}[/tex]

Step-by-step explanation:

[tex]\textsf{We are asked to solve for x in the given equation.}[/tex]

[tex]\textsf{Note that our goal is to leave x alone on the left side of the equation. In order}[/tex]

[tex]\textsf{to do so we will need to use the \underline{Properties of Equality}.}[/tex]

[tex]\large\underline{\textsf{What are the Properties of Equality?}}[/tex]

[tex]\textsf{Properties of Equality are 9 Properties that allows us to manipulate equations}[/tex]

[tex]\textsf{to, commonly find unknown variables or to determine if equations are true.}[/tex]

[tex]\textsf{For our problem, we will be using 2 out of 9 of these properties as we need to}[/tex]

[tex]\textsf{isolate x, and make sure x is 1x.}[/tex]

[tex]\large\underline{\textsf{Solving for x;}}[/tex]

[tex]\tt \frac{1}{2} x-41=181[/tex]

[tex]\textsf{Let's first use the Addition Property of Equality where the equation will be equal}[/tex]

[tex]\textsf{if we add the same number to both sides of the equation. Let's start by adding}[/tex]

[tex]\textsf{41 to both sides of the equation.}[/tex]

[tex]\tt \frac{1}{2} x-41+41=181+41[/tex]

[tex]\tt \frac{1}{2} x = 222[/tex]

[tex]\textsf{Next, let's use the Multiplication Property of Equality where the equation is}[/tex]

[tex]\textsf{equal if we multiply the same number to both sides of the equation. Let's}[/tex]

[tex]\textsf{multiply 2 to both sides of the equation to cancel out} \ \tt \frac{1}{2} .[/tex]

[tex]\tt 2 \times \frac{1}{2} x = 222 \times 2[/tex]

[tex]\large\boxed{\tt x = 444.}[/tex]

Answer:

Step-by-step explanation:

Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

a). A(-6, -4), B(-3, -1)

Distance between A and B = [tex]\sqrt{(-6+3)^2+(-4+1)^2}[/tex]

                                             = [tex]\sqrt{9+9}[/tex]

                                             = 3√2

                                             = 4.2 units

b). C(3.5, 1), D(-4, 2.5)

Distance between C and D = [tex]\sqrt{(3.5+4)^2+(1-2.5)^2}[/tex]

                                              = [tex]\sqrt{58.5}[/tex]

                                              = 7.65

                                              ≈ 7.7 units

c). Distance between X(5, -5) and Y(-5, 5)

    Distance = [tex]\sqrt{(5+5)^2+(-5-5)^2}[/tex]

                    = [tex]\sqrt{200}[/tex]

                    = 10√2

                    = 14.14

                    ≈ 14.1 units

Answer:

-9n + 36

Step-by-step explanation:

1. -9(n - 4)    -Distribute

2. -9n + 36  -Answer

[tex]\huge\fbox{\sf{Answer:~~{\boxed{-9n+36}}}}[/tex]

Step-by-step explanation:

Hi there!

Let's simplify this expression. It's easy, because all we have to do is "distribute"  -9:

[tex]\bold{-9(n-4)}[/tex]

[tex]\bold{-9n+36}[/tex]

Answer:

the answer is 2

Step-by-step explanation:

2(4)-3(2)=

8-6=2

Answer: Ok while i was working out this problem I started by multiplying so i started by 5

2.50 x 5 = 12.5

3.25 x 5 = 16.25 then I added then and got 28.75. So i was like i should go higher. I picked 7.

2.50 x 7 = 17.5

3.25 x 7 = 22. 75 then I added those two and got 40.25 when i got that I was like yes, Im getting closer. So i picked 9 then I got..

2.50 x 9 = 22.5

3.25 x 9 = 29.25 and that equaled 51.75

so then i was like oh! Taxes so I think the answer might be 8. 46 plus tax lol.

Answer:

94.5%

Step-by-step explanation

Answer:

5units

Step-by-step explanation:

Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.

Using the formula

D = √(x2-x1)²+(y2-y1)²

D = √(2-2)²+(8-3)²

D = √0+5²

D =  √25

D = 5

Hence the length of the side of the rectangle is 5units
