Sunday

- gross: $120

- net: $101.38

Josh collected 60 stickers, Ann collected 67 stickers and Claire collected 30 stickers.

Ann, Claire and Josh collect stickers. One week, Ann collects 7 more stickers than Josh.

let use variables to represent the amount of stickers they collected.

Therefore, Ann collects 7 more stickers than Josh. Josh collects twice as many stickers as Claire

Josh stickers = x

Ann stickers = 7 + x

Claire stickers = 1 / 2 x

Total stickers collected = 157

Therefore,

x + 7 + x + 1 / 2 x  = 157

x + x + 1 / 2 x = 157 - 7

2.5x = 150

divide both sides by 2.5

x = 150 / 2.5

x = 60

Therefore, Josh collected 60 stickers, Ann collected 67 stickers and Claire collected 30 stickers.

By substitution, the solution of the system of equations, x + 12y = 68 and x = 8y - 12, is (20 , 4).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in x and y,

x + 12y = 68     (equation 1)

x = 8y - 12     (equation 2)

Since the second equation is already expressed in x in terms of y, substitute the value of x to the first equation.

x + 12y = 68     (equation 1)

(8y - 12) + 12y = 68

8y - 12 + 12y = 68

Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.

8y - 12 + 12y = 68

8y + 12y = 68 + 12

20y = 80

y = 4

Substitute the value of y in the second equation and solve for x.

x = 8y - 12     (equation 2)

x = 8(4) - 12

x = 32 - 12

x = 20

Hence, the solution of the given system of equations is (20 , 4).

The vertex and range are (-2, -3) and y >= -3 respectively

The equation is given as:

y = |x +2| - 3

The above equation is an absolute value equation

An absolute value equation is represented as:

y = a|x - h| + k

Where

Vertex = (h, k)

So, we have

Vertex = (-2, -3)

Also, we have

a = 1

Since a is positive, then the vertex is a minimum

Hence, the vertex and range are (-2, -3) and y >= -3 respectively

The number of chickens are J. 90.

Let the chickens be represented by x and the pigs be represented by y.

Forming the equation according to first information -

Equation 1 : x + y = 120

x = 120 - y

Both chicken and pig has one head. Chicken has 2 feet while pig has 4 feet. Forming the equation according to second information -

Equation 2 : 2x + 4y = 300

Simplifying the equation 2 by dividing by number 2

x + 2y = 150

Keep the value of x from equation 1 in equation 2

120 - y + 2y = 150

Performing subtraction

120 + y = 150

Further shifting the value and performing subtraction

y = 150 - 120

Performing subtraction

y = 30

Now, 30 is the number of pigs.

Number of chickens = 120 - y

Number of chickens =  120 - 30

Number of chickens = 90

Hence, the number of chickens the farmer has is J. 90.

Answer:16 and 24

Step-by-step explanation:

The find two consecutive odd integers is 7 and 9

These are functions that has a linear degree of 1. Let the two consecutive odd numbers be 2x + 1 and 2x + 3

If their product is the same as fifteen more than three times their sum, then;

(2x+1)(2x+3) = 3(2x+1+2x+3) +15

4x²+6x+2x+3 = 3(4x+4)  +15

4x²+8x+3 = 12x+12 + 15

4x² - 4x + 3 = 27

4x² - 4x - 24 = 0
x² - x - 6 = 0

On factorizing, the value of x is 3 and -2

First number = 2(3) + 1 = 7

Second number = 2(3) + 2 = 9

Hence the find two consecutive odd integers is 7 and 9

The length of slant height l is √98 ft. when diameter of cone and  height of cone is 7 ft.

What is Mathematical function ?

Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.

Here, the diameter of cone is given as : 14ft.

also, the height of cone is : 7 ft.

the radius r of base will be half of diameter :

r = b/2  

r = 14/2 = b

Now to find the slant height of the cone we use Pythagoras theorem between the base of cone b, height of cone h and slant height l that is :

h² + r² = l²

7² + 7 ² = l²

l² = (2x7²)

l = 7 √2 ft. or √98 ft.

Therefore, the length of slant height l is √98 ft.

Measure of angle 5 i.e. m∠5 = 50°

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Thus, m∠5 = 50°

The solution of the given linear equation 3(w -8) = 36 in one variable is at w = 20.

According to the given question.

We have a linear equation in one variable 3(w - 8) = 36.

Since, we have to solve the above equation for w.

As we know tha, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Therefore, the solution of the linear equation in one varibale 3(w - 8) = 36 is given by

3(w - 8) = 36

⇒3w - 24 = 36      ( by distributive property)

⇒ 3w = 36 + 24     (adding 24 both the sides)

⇒ 3w = 60

⇒ w = 60/3   (dividing both the sides by 3)

⇒ w = 20

Hence, the solution of the given linear equation 3(w -8) = 36 in one variable is at w = 20.
