Answer:

C. q= -9

Step-by-step explanation:

4=q+13

-13    -13     (4-13= -9)

q=-9

hope this helps :)

The solution of the given equation 4=q+13 is -9. Thus option C is correct.

The equation is defined as an expression consisting of an equality sign.

let us consider an example  :

[tex]2x - 5 = 13.[/tex]

The given equation is:

[tex]4 = q + 13 \rightarrow 1[/tex]

For part A when q = 4 (given)

on substituting the value in equation 1 we get,

On transposing 13 to opposite side we get,

[tex]4 -13 = q[/tex]

[tex]-9 = q[/tex]

rewrite the equation as,

[tex]q =9[/tex]

The solution of the given equation [tex]4=q+13[/tex] is -9.

Step-by-step explanation:

the formula is to square the number then subtract the preceding number in the box

The length of the rectangle is 12feet and the width is 26feet.

The formula for calculating the perimeter of a rectangle is expressed according to the equation below:

Perimeter = 2(length + width)

If the width is 3 times the next consecutive integer, then;

w = 3(x+1)

l = x

Substitute

102 = 2(x + 3x + 3)

102 = 2(4x + 3)

102/2 = 4x+ 3

51 = 4x + 3

4x = 48

x = 12 = length

For the width

width = 2(x+1)

width = 2(12+1)

width - 26 feet

Hence the length and the width of the rectangle are 12 feet and 26 feet respectively

The solution of the given equation by rounding off it to the nearest ten-thousandth is 20716.0000.

What is a round-off of the digit?

In mathematics, a round-off is defined as an approximation of the given number to a fewer number of significant digits by taking into consideration some rules.

For eg: 13.58 ~ 13.6

Solving the given equation: 12⁴ - x = 20

We are given that 12⁴ - x = 20            —- 1

We know that 12⁴ = 20736

So, equation 1 becomes,

20736 - x = 20

x = 20736 - 20

= 20716

Based on the information, it should be noted that there be 67 adults and 733 students in the auditorium.

Let adults tickets = a

Let students tickets = s

The auditorium at McCaskey East High School in Lancaster, PA has 800 seats. This will be:

a + s = 800 ..... i

Therefore, suppose that the drama club has a goal of making $3400. This will be:

7a + 4s = 3400 ..... ii

From equation i, a = 800 - s.

7a + 4s = 3400

7(800 - s) + 4s = 3400

5600 - 7s + 4s = 3400

Collect like terms

-7s + 4s = 3400 - 5600

3s = -2200

s = 2200 / 3

s = 733

a = 800 - 733 = 67

Therefore, there'll be 67 adults and 733 students.

Sarah have $495 in her account at the end of the month.

Given,

The amount Sarah had in her bank account at the beginning of the month = $600

The deposits she made within the month = $40 and $25

The withdrawals she made = $100, $50 , $20

We have to find the balance amount in Sarah's account after all these transactions made:

The deposits Sarah had = 600 + 40 + 25 = 665

Sarah had $665 in her account in a month.

Withdrawals made by Sarah = 100 + 50 + 20 = 170

Sarah made a total withdrawal of $170 in the month.

Now, we have to find the account balance of Sarah:

Account balance = Total deposits - Total withdrawals

Account balance = 665 - 170 = 495

Step-by-step explanation:

The length of each piece of rope is 10m.

The first step is to determine the length of the rope before it was cut. In order to determine the length of the rope, multiply the length of the stick by the number of times the rope is as long as the stick.

Multiplication is the process that is used to determine the product of two or more numbers. The sign that is used to represent multiplication is x.

Length of the rope = length of the stick x 4

4 x 5 = 20m

lf the length of the rope is divided into two prices, divide the length of the rope by 2. Division is the mathematical operation that is used to determine the quotient of two or more numbers. It entails grouping a number into equal groups using another number.

Parallel: y = -4x + 23

Perpendicular: y = (1/4)x - (5/2)

Step-by-step explanation:

Parallel Line:

y = -4x + 1; (6, -1)

                  (x₁, y₁)

y - y₁ = m (x - x₁)

y - (-1) = -4 (x - 6)

y + 1 = -4 (x - 6)

y + 1 = -4x + 24

y = -4x + 23

----------------------------------------------------------------------------------------------------------

Perpendicular:

y = (1/4)x + 1

y - y₁ = m (x - x₁)

y - (-1) = (1/4) (x - 6)

y + 1 = (1/4) (x - 6)

y + 1 = (1/4)x - (6/4)

Given the radius of each sphere, the volume of sphere A and B are 33.49cm³ and 267.95cm³ respectively.

A sphere is simply a geometrical object with a three-dimensional analogue to a two-dimensional circle.

The volume of a sphere is expressed as;

V = (4/3) × π × r³

Where r is radius and π is constant pi ( π = 3.14 ).

Given the data in the question;

First, we determine the volume of sphere A.

V = (4/3) × π × r³

V = (4/3) × 3.14 × (2cm)³

V = (4/3) × 3.14 × 8cm³

V = 33.49cm³

Hence, the volume of sphere A is approximately 33.49cm³.

Next, we determine the volume of sphere B.

V = (4/3) × π × r³

V = (4/3) × 3.14 × (4cm)³

V = (4/3) × 3.14 × 64cm³

V = 267.95cm³

Hence, the volume of sphere Bis approximately 267.95cm³.

The answer of the following fraction which involves ABC is said to be  12:20:25

The transformation of a ratio into a fraction is known as the simple fraction form. In order to convey the relative size of two or more variables, the ratio is utilized. The fraction similarly identifies the components of the total. A:B or a/B are two ways to represent the ratio. As an illustration, the ratio is 12: 15.

Express the ratio in terms of a

a/b = 3/5 (cross-multiply)

3b = 5a (Divide the total both sides by 3)

b= 5/3 a

b/c = 4/5 (cross-multiply)

4c = 5b (divide the total both sides by 4)

c= 5/4 b=5/4×5/3 a=25/12a

then

a:b:c

=a:5/3 a:25/12 a (multiply each part by 12 to clear the fractions)

=12a:20a:25a (divide each part by a)

2x = x + 5

Subtracting x on both the sides of the equations, we get
