Answer:

60

Step-by-step explanation:

divide 39 by 65%,

you will get
39 / ( 65/ 100)
= 39 * (100/65)
= 39 * (20 /13)
= 3*20

Using a system of equations, the amounts of each ticket sold are given as follows:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

The theater sold 250 tickets, hence:

x + y + z = 250.

The theater brought in $2,825, hence, considering the value of each ticket:

15x + 10y + 8z = 2825.

The number of student tickets sold is twice the number of adult tickets sold, hence:

y = 2x.

Replacing in the first two equations:

Multiplying the first equation by -8 and adding with the second, we have that:

11x = 825

x = 825/11

x = 75.

Then:

The amounts of each ticket sold are given as follows:

Step-by-step explanation:its a

the value of largest integer when the sum of 3 consecutive odd integers is 153 is 53.

We know that odd consecutive numbers means the difference between the numbers will be 2

So, let the first odd number be x

Second number will be = x + 2

Third number will be = x + 2 + 2 = x + 4

Now, we are given that, the sum of these odd integers is 153

So, we get the equation as:

x + x + 2 + x + 4 = 153

3 x + 6 = 153

3 x = 153 - 6

3 x = 147

x = 147 / 3

x = 49

Largest integer = x + 4 = 49 + 4 = 53

Therefore, we get that, the value of largest integer when the sum of 3 consecutive odd integers is 153 is 53.

Answer: -48

Step-by-step explanation:

k/3 + 16

find the roots by factoring

which leads to -48

k/3 + 16

To add or subtract expressions, expand them so their denominators are the same. Multiply 16 by 3/3.

                   k/3 + 16 × 3/3

Since k/3 and 16 × 3/3 have the same denominator, we join their numerators to add them.

                          k + 16 × 3/3

We perform the multiplications in k+16×3.

The multiplication equation to find 5 divided by 1/3 is 5 x 3 = 15.

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

At an elementary level the division of two natural numbers is, among other possible interpretations, the process of calculating the number of times one number is contained within another.

Unlike the other basic operations, when dividing natural numbers there is sometimes a remainder that will not go evenly into the dividend.

Division has two parts dividend and divisor.

Division is not commutative, meaning that a / b is not always equal to b / a.

Division is also not, in general, associative.

Division is traditionally considered as left-associative.

Division is right-distributive over addition and subtraction.

Division is shown in algebra and science by placing the dividend over the divisor with a horizontal line, also called a fraction bar, between them. For example, "a divided by b" can written as:

a/b

Now it is given that,

5 divided by 1/3

This can be expressed as,

5 divided by 1/3 = 5 ÷ 1/3

Since to convert the division of fraction into multiplication, we reciprocate the fraction

So, applying division we get,

5 ÷ 1/3 = 5 x 3

So, the multiplication equation is,

5 x 3

Now multiplying 5 and 3 we get,

5 x 3 = 15

this is the required multiplication equation of 5 divided by 1/3.

Thus, the multiplication equation to find 5 divided by 1/3 is 5 x 3 = 15.

Answer:

x = -2

Step-by-step explanation:

Solve for x:

-5 x - 10 = -(x + 4) + 2

-(x + 4) = -x - 4:

-5 x - 10 = (-x - 4) + 2

Grouping like terms, -x - 4 + 2 = -x + (2 - 4):

-5 x - 10 = (-x + (2 - 4))

2 - 4 = -2:

-5 x - 10 = -x + -2

Add x to both sides:

x - 5 x - 10 = (x - x) - 2

x - x = 0:

x - 5 x - 10 = -2

Grouping like terms, x - 5 x - 10 = (-5 x + x) - 10:

((-5 x + x) - 10) = -2

x - 5 x = -4 x:

-4 x - 10 = -2

Add 10 to both sides:

(10 - 10) - 4 x = 10 - 2

10 - 10 = 0:

-4 x = 10 - 2

10 - 2 = 8:

-4 x = 8

Divide both sides of -4 x = 8 by -4:

(-4 x)/(-4) = 8/(-4)

(-4)/(-4) = 1:

x = 8/(-4)

The gcd of 8 and -4 is 4, so 8/(-4) = (4×2)/(4 (-1)) = 4/4×2/(-1) = 2/(-1):

x = 2/(-1)

Multiply numerator and denominator of 2/(-1) by -1:

Answer: x = -2

Answer:

Step-by-step explanation:

The area of the six-sided polygon = 220.5 square ft.

Given that the six-sided polygon consists of two isosceles triangles and a rectangle. So the total area to be cut will be equal to the sum of areas of the triangles and the rectangle.

First triangle has base = 15 ft and height = 15 ft

Area of a 1st triangle = 1/2 x base x height

                             = 1/2 x 15 x 15

                             = 112.5 square feet

Second triangle has base = 4 ft and height = 4 ft

Area of the 2nd triangle = 1/2 x base x height

                                        = 1/2 x 4 x 4

                                        = 8 square ft

The rectangle has length = 25 ft and width = 4 ft

Area of the rectangle = length x width

                                    = 25 x 4

                                    = 100 square ft

So the total area of the six-sided polygon = 112.5 + 8 + 100

                                                                      = 220.5 square ft.
