Step-by-step explanation:

Let Maya's age is m.

Sax age is 3 years older than twice Maya's age

Sax age = 2m +3

Zach age = 23 years

We need to find the equation that is used to solve Maya's age. ATQ,

2m + 3 = 23

If we solve,

2m = 23-3

2m = 20

m = 10

Hence, this is the required solution.

Answer:

Cost of the binder = $5

Cost of the highlighter = $2.5

Cost of the folder = $2

Step-by-step explanation:

Let

Cost of the binder = x

Cost of the highlighter = 1/2x

Cost of the folder = x - 3

Total cost = $9.50

Total cost = Cost of the binder + Cost of the highlighter + Cost of the folder

9.50 = (x) + (1/2x) + (x-3)

9.50 = x + 1/2x + x - 3

9.50 + 3 = x + 1/2x + x

12.50 = 2x + 1/2x

12.50 = 2 1/2x

12.50 = 5/2x

x = 12.50 ÷ 5/2

= 12.50 × 2/5

= 25/5

x = $5

Cost of the binder = x = $5

Cost of the highlighter = 1/2x = 1/2*6 = $2.5

Cost of the folder = x - 3

= 5 - 3 = $2

Answer:

x = 12

Step-by-step explanation:

The hexagonal tile given here is made up of 6 triangles with equal bases and heights.

So, area of hexagonal tile will be equal to 6 times the area of one triangle.

Therefore,

[tex]18 \sqrt{3} = 6 \times \frac{1}{2} \times 2 {( \sqrt{3)} }^{ \frac{x}{12} } . {( \sqrt{3)} }^{ \frac{x}{6} } \\ \\ 18 \sqrt{3} = 6 {( \sqrt{3)} }^{ \frac{x}{12} } . {( \sqrt{3)} }^{ \frac{2x}{12} } \\ \\ \frac{18 \sqrt{3} }{6} = {( \sqrt{3)} }^{ \frac{x}{12} + \frac{2x}{12} } \\ \\ 3 \sqrt{3} = {( \sqrt{3)} }^{ \frac{3x}{12} } \\ \\ 3. {3}^{ \frac{1}{2} } = {3}^{ \frac{3x}{24} } \\ \\ {3}^{1 + \frac{1}{2} } = {3}^{ \frac{x}{8} } \\ \\ {3}^{ \frac{3}{2} } = {3}^{ \frac{x}{8} } \\ (bases \: are \: equal \: so \: exponents \: \\ will \: also \: be \: equal) \\ \implies \frac{3}{2} = \frac{x}{8} \\ \\ x = \frac{3 \times 8}{2} \\ \\ x = 3 \times 4 \\ \\ x = 12[/tex]

The area of the hexagon-shaped tile is the amount of space it occupies

The value of x is 2

The given parameters are:

[tex]\mathbf{Area = 18\sqrt 3}[/tex]

[tex]\mathbf{Base= (\sqrt 3)^{\frac x6}}[/tex]

[tex]\mathbf{Height = 2(\sqrt 3)^{\frac x{12}}}[/tex]

The shape is a regular hexagon (i.e. it has 6 equal sides).

So, the area of one of the segments is the total area divided by 6 and this is calculated as:

[tex]\mathbf{A(1) = \frac{18\sqrt 3}6}[/tex]

[tex]\mathbf{A(1) = 3\sqrt 3}[/tex]

A segment of the hexagon is a triangle, and the area of a triangle is:

[tex]\mathbf{Area = \frac 12 \times Base \times Height}[/tex]

So, we have:

[tex]\mathbf{3\sqrt 3= \frac 12 \times (\sqrt 3)^{\frac x6} \times 2(\sqrt 3)^{\frac{x}{12}}}[/tex]

This gives

[tex]\mathbf{3\sqrt 3= (\sqrt 3)^{\frac x6} \times \sqrt 3)^{\frac{x}{12}}}[/tex]

Apply law of indices

[tex]\mathbf{3\sqrt 3= (\sqrt 3)^{\frac x6 + \frac{x}{12}}}[/tex]

Add the exponents

[tex]\mathbf{3\sqrt 3= (\sqrt 3)^{\frac x4}}[/tex]

Express the equations as a base of 3

[tex]\mathbf{3^{\frac 32}= 3^{\frac x8}}[/tex]

Cancel out the base

[tex]\mathbf{\frac 32= \frac x8}[/tex]

Multiply through by 8

[tex]\mathbf{12= x}[/tex]

Rewrite as:

[tex]\mathbf{x = 12}[/tex]

Hence, the value of x is 2

Step-by-step explanation:

Answer:

0.3, 33%, 1/3, pi x 10-1

Step-by-step explanation:

Let's simplify all of them so that they're in the same form. 33% is 0.33 as a decimal, since a percentage is out of 100. 1/3 is equal to 0.33333 repeating as a decimal--This one is just one that you have to memorize. 1 divided by 3 will give you your answer. Next, pi multiplied by 10: pi is roughly 3.14159 to the hundred-thousandths place. So we multiply that by 10, giving us 31.4159. -1 gives us 30.4159.

So:

0.3, 33%, 1/3, and lastly pi x 10-1

Step-by-step explanation:

For number 1, the angles are alternate exterior which means that they are equivalent. 2x-20 = x + 26. x=46. Number 2, 2x-80=90. 2x=170. x=85. Number 3, the angles are supplementary in which their sum is 180. (x+20)+(x-15)=180. 2x=175. x=87.5

Step-by-step explanation:

yes because after the first rotation the triangle formes a parallelogram, because the interior angles are equal, because the parallelogram is basically formed of two identical triangles. after the second rotation the triangle forms yet another parallelogram(the one "glued" to the initial triangle) for the same reason. in conclusion the bases of the final quadrilateral will always be paralel because of the parallelograms=>it will always be a trapezoid

21^7~28 I think I learnt a different way to every one

Answer:

Step-by-step explanation:

Given that:

[tex]f(x) = x^3 + x - 3 = 0[/tex]

Since the given function is equal to zero, then the function :

[tex]f(x) = x^3 + x - 3[/tex]

where;

[tex]x = 1[/tex] and

[tex]x = 2[/tex]

[tex]f(x) = (1)^3 + (1) - 3 \\ \\ f(x) = 1 + 1 - 3 \\ \\f(x) = -1 < 0[/tex]

[tex]f(2) = x^3 + x - 3 \\ \\f(2) = (2)^3 + 3 - 3 \\ \\f(2) = 8 + 3 - 3 \\ \\f(2) = 11 - 3 \\ \\f(2) = 8 > 0 \\ \\[/tex]

Thus; f(1) < 0 and f(2) > 0

Given:

[tex]\to x^3 + x -3 =0[/tex]

x in between 1 and 2

To find:

value=?

Solution:

[tex]\to x^3 + x -3 =0[/tex]

put value x= 1 and x in 2 in the above equation:

[tex]\to 1^3 + 1 -3 =0\\\\\to 1 + 1 -3 =0\\\\\to 2 -3 =0\\\\\to -1=0\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Equation (a)} \\\\ \to 2^3 + 2 -3 =0\\\\\to 8+ 2 -3 =0\\\\\to 10 -3 =0\\\\\to 7=0\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Equation (b)}[/tex]

Therefore the equation a < 0 and equation b > 0.
