Answer:

272/-13 or −20.923

Step-by-step explanation:

To solve this equation you need to isolate the variable.

First, add 71 to both sides

-13x-71+71=201+71

-13x=272

Then, divide both sides by -13

-13x/-13=272/-13

So, x=272/-13 or −20.923

Answer:

$225 = $15 a + $ 10 c

Given,

Total price = $225

Cost of concert ticket for adults= $15

Cost of concert ticket for children = $10

System of equation to represent scenario

a is variable for adult

c is variable for children

Now,

Total price =  $15 a + $ 10 c

$225 = $15 a + $ 10 c

Answer:

The required volume, if he wants to fill 75% of the pot's volume, is 11664cm³

Step-by-step explanation:

The volume of a pyramid is given as

[tex]V = \frac{1}{3} \times A \times h[/tex]

Where V is the pot's volume, A is the base area and h is the height.

Our base is a square, so the base area, if s denotes the side length, would be s x s.

s = 36cm, therefore we have A = 36cm X 36cm = 1296cm².

The height is given as 36cm, therefore we have our volume to be:

[tex]V = \frac{1}{3} \times 1296cm^2 \times 36cm[/tex]

[tex]V = 15552cm^3[/tex]

Since Luis wants to fill 75% of the pot's volume with soil. Then it will take

[tex]\frac{75}{100} \times 15552cm^3 = 11664cm^3 [/tex]

Thus, the required volume, if he wants to fill 75% of the pot's volume, is 11664cm³

Step-by-step explanation:

Answer:

[tex] Slope (m) = -\frac{3}{4} [/tex]

Step-by-step explanation:

Using any two pairs from the table of values given, (-2, 5) and (2, 2):

[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Where,

[tex] (-2, 5) = (x_1, y_1) [/tex]

[tex] (2, 2) = (x_2, y_2) [/tex]

Plug in the value into the slope formula:

[tex] Slope (m) = \frac{2 - 5}{2 -(-2)} [/tex]

[tex] Slope (m) = -\frac{3}{4} [/tex]

Hope this helps!

Step-by-step explanation:

The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.

Given:

Scale factor is [tex]\dfrac{1}{144}[/tex].

Length of wingspan of the airplane = 1152 inches

To find:

The length of wingspan of the model airplane.

Solution:

Scale factor is [tex]\dfrac{1}{144}[/tex]. It means,

1 inches of airplane [tex]=\dfrac{1}{144}[/tex] inches of model airplane.

1152 inches of airplane [tex]=1152\times \dfrac{1}{144}[/tex] inches of model airplane

                                       [tex]=8[/tex] inches of model airplane

Therefore, the length of wingspan of the model airplane is 8 inches.

Answer:

11x^2-11x+4

Step-by-step explanation:

(6x ^ 2 - x + 3)-( - 5x ^ 2 + 10x - 1 )

6x^2-x+3+5x^2-10x+1

11x^2-11x+4

So the answer is 11x^2-11x+4

Answer:

[tex]\displaystyle y=\frac{16-9x^3}{2x^3 - 3}[/tex]

[tex]\displaystyle y=-\frac{56}{13}[/tex]

Step-by-step explanation:

Equation Solving

We are given the equation:

[tex]\displaystyle x=\sqrt[3]{\frac{3y+16}{2y+9}}[/tex]

i)

To make y as a subject, we need to isolate y, that is, leaving it alone in the left side of the equation, and an expression with no y's to the right side.

We have to make it in steps like follows.

Cube both sides:

[tex]\displaystyle x^3=\left(\sqrt[3]{\frac{3y+16}{2y+9}}\right)^3[/tex]

Simplify the radical with the cube:

[tex]\displaystyle x^3=\frac{3y+16}{2y+9}[/tex]

Multiply by 2y+9

[tex]\displaystyle x^3(2y+9)=\frac{3y+16}{2y+9}(2y+9)[/tex]

Simplify:

[tex]\displaystyle x^3(2y+9)=3y+16[/tex]

Operate the parentheses:

[tex]\displaystyle x^3(2y)+x^3(9)=3y+16[/tex]

[tex]\displaystyle 2x^3y+9x^3=3y+16[/tex]

Subtract 3y and [tex]9x^3[/tex]:

[tex]\displaystyle 2x^3y - 3y=16-9x^3[/tex]

Factor y out of the left side:

[tex]\displaystyle y(2x^3 - 3)=16-9x^3[/tex]

Divide by [tex]2x^3 - 3[/tex]:

[tex]\mathbf{\displaystyle y=\frac{16-9x^3}{2x^3 - 3}}[/tex]

ii) To find y when x=2, substitute:

[tex]\displaystyle y=\frac{16-9\cdot 2^3}{2\cdot 2^3 - 3}[/tex]

[tex]\displaystyle y=\frac{16-9\cdot 8}{2\cdot 8 - 3}[/tex]

[tex]\displaystyle y=\frac{16-72}{16- 3}[/tex]

[tex]\displaystyle y=\frac{-56}{13}[/tex]

[tex]\mathbf{\displaystyle y=-\frac{56}{13}}[/tex]

Reciprocal is reversing the given fraction.

1. Would be 8/3

2. 2 2/3 as in improper fraction is 8/3, reciprocal would be 3/8

3. -3/8 x 8/3 = -24/24 = -1

4. 3/8 / -8/3 =3/8 x -3/8 = -9/64

5. - 8/3 - -3/8 = -8/3 + 3/8 = -2 7/24

6. Only answer left: 2 7/24
