Answer:

x= 6

Step-by-step explanation:

To find the value of x that makes the equation true, first shift all the x terms to one side of the equation.

6x -3x= 18

Simplify:

3x= 18

Divide both sides by 3:

x= 18 ÷3

x= 6

       What value of x makes the equation [tex]\large\textit{6x=3x+18}[/tex] true?

[tex]\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}[/tex]

   [tex]\dagger[/tex] When solving an equation, we need to make sure that variables are on one side of the equation, which is usually the left-hand side,  and numbers are on the other side, which is usually the right-hand side, of the equation.

[tex]\bigstar[/tex] Since we have variables on the right-hand side as well as the left-hand side, we need to move all of them to the left-hand side, with the opposite operation:-

[tex]\sf{6x-3x=18}[/tex]                Subtract 6x-3x:-

[tex]\sf{3x=18}[/tex]                 Now, divide by 3 on both sides:-

[tex]\boxed{\boxed{\sf{x=6}}}\checkmark[/tex]

         We can do that by substituting 6 for x (into the original equation)

       and seeing whether or not we have a true statement:-

        [tex]\implies\sf{6(6)=3(6)+18}[/tex]

       [tex]\implies\sf{36=18+18}[/tex]

      [tex]\implies\sf{36=36}[/tex]

     [tex]\bigstar[/tex] Since the LHS equals the RHS, our solution (x=6) is correct.

Shoe box is an example of rectangular prism.

Classroom ↬ m²

Book ↬ cm²

Matchbox ↬ mm²

8 cm³ = 0.000008 m³ or 8 × 10⁻⁶ m³

28 m³ = 28000000 cm³ or 2.8 × 10⁷ cm³

95 cm³ = 0.095 L

To solve this problem, we have to apply mole-concept to this and we would need the molar mass of AlCl3.  2g of AlCl3 contains 9.034*10^21 molecules.

The molar mass of AlCl3 is given as 133.34g/mol

Data;

Using the mole concept, we can equate the molar mass to the number of molecules present in the entity.

[tex]133.34g = 6.023*10^2^3[/tex]

If we equate this

[tex]133.34g = 6.023*10^2^3\\2g = x molecules\\x = \frac{2*6.023*10^2^3}{133.34} \\x = 9.034*10^2^1 molecules[/tex]

From the calculations above, 2g of AlCl3 contains 9.034*10^21 molecules.

A) The areas of two congruent figures are equal.

Step-by-step explanation:

Solution:

2nd, 3rd, and 4th statements are formulas, not theorems.

Areas of two congruent figures that are equal is a theorem.

Step-by-step explanation:

The system of equations for eq 1 which is 3x + y = 118 represents the Green High School which filled three buses(with a specific number of students identified as x) and a van(with a specific number of students identified as y) with a total of 118 students.

for eq 2; 4x + 2y = 164; represents Belle High School which filled four buses(with a specific number of students identified as x) and two vans(with a specific number of students identified as y) with a total of 164 students.

The solution represents the specific number of students in the buses and vans in eq1 and eq 2 with x being 36 students and y being 10 students.

substituting 36 for x and 10 for y in eq 1;

3(36) + 10 = 108 + 10 = 118 total students for Green High School

substituting 36 for x and 10 for y in eq2;

4(36) + 2(10) = 144 + 20 = 164 total students for Belle High school

Answer:

B) d=4t

Step-by-step explanation:

let's look at two points

1. t=0, d = 0

2. t = 1, d = 4

slope = change in vertical axis (d)/ change in horizontal axis (t)

change in d = 4 = d₂-d₁

change in t = 1 = t₂-t₁

slope = 4/1 = 4

vertical variable = slope * horizontal variable + horizontal axis intercept

d = 4 * t + horizontal axis intercept

horizontal axis intercept is the vertical axis variable (d) when the horizontal axis variable (t) is at 0. at t=0, d=0

thus, d = 4 * t + 0

d = 4t (B)

This are used to determine the maximum or minimum of a function. The vertex form of the function is given as y = 3(x+2)² - 5

This are used to determine the maximum or minimum of a function. Give the quadratic equation expressed as:
y = 3x² + 12x + 7

The vertex form of the function will be in the form y = a(x-h)² + k

Complete the square

y = 3(x² + 4x) + 7

y = 3(x² + 4x + 2² - 2²) + 7
y = 3(x+2)² - 3(4) + 7

y = 3(x+2)² - 5

Hence the vertex form of the function is given as y = 3(x+2)² - 5

For the expression y5y3−(y−2)4 the correct value is in the first tile, and for the expression (y−2)4+y3y5 the correct value is in the fifth tile.

Exponents that should be integers are known as integer exponents in mathematics. It could be either a positive or negative integer. The positive integer exponents specify how many times the base number should be multiplied by itself in this case.

We have:

[tex]=\rm y^5y^3-(y^{-2})^4[/tex]

[tex]= \rm y^{5+3}-(y^{-2\times4})[/tex]

Step-by-step explanation:

The question is asking: "Which numbers can be multiplied by themselves and equal 9?" You can formally find this answer by taking the square root of 9, the opposite of squaring a number. Or, in this case, you can try the guess-and-check method. Remember, multiplying two negative numbers together results in a positive answer.

A.) is incorrect because 81 x 81 = 6561 and -81 x -81 = 6561.

B.) I'm assuming this answer is [tex]\sqrt{3}[/tex] (if it's not, there is still a better answer). This answer is incorrect because [tex]\sqrt{3}[/tex] x [tex]\sqrt{3}[/tex] = 3.
