Answer:

[tex]x=0[/tex]

Step-by-step explanation:

[tex]-7x - 12 = - 7x + 3(-4 - x)[/tex]

Open up the parentheses

[tex]-7x - 12 = - 7x -12-3x[/tex]

-7x cancels out on both sides

[tex]-12 =-12-3x[/tex]

-12 cancels out on both sides

The number of visits when you would receive a discount and a free product at the same time is on the 20th visit.

A multiple of a number is the product of an integer and that number. For example a multiple of 10 is 120. This is because the product of 10 and 12 is 120.

In order to determine the number of visit, the multiple of 4 and 10 has to be determined. The first common multiple is required answer

The first ten multiples of 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40

The first ten multiples of 10 = 10, 20, 30, 40, 50, 60, 70, 80, 90, 100

Full question:

A transaction is positive if there is a sale and negative when there is a return. Each time a customer uses credit card for a transaction, the credit company charges Isabel. The credit company charges 1.5% of each sale and a fee of 0.5 % for returns

Let x represent the amount of a transaction and let f(x) represent the amount Isabel is charged for the transaction. Write a function that expresses f(x)

Answer:

f(x)= 0.015(x)

f(x)= 0.005(x)

Explanation:

If Isabel makes a sale, she has a positive transaction and therefore is charged 1.5%(which is 0.015) by the credit company for the transaction. If the product is returned, it is a negative transaction and the credit company charges 0.5%(which is 0.005) for the transaction. The functions for positive and negative transactions would be different as indicated in the answer since transactions( given by x) are different- positive and negative.

Answer:

(-2, -4)

Step-by-step explanation:

Since both equations are equal to y, you can set them equal to each other:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3[/tex]

Next, solve for x:

[tex]\frac{3}{2}x-1=\frac{1}{2}x-3\\x-1=-3\\x=-2[/tex]

Finally, substitute the solution for x in one of the equations (or both) to find y:

[tex]y=\frac{3}{2}(-2)-1\\y=-3-1\\y=-4[/tex]

[tex]y=\frac{1}{2}(-2)-3\\y=-1-3\\y=-4[/tex]

Therefore, the solution to the system of equations is (-2, -4).

Answer:

1/10 acres

Step-by-step explanation:

A land developer wants to divide up 9/10 of an acre Of land into equally sized lots for houses. He wants to build nine houses. How big can he make each lot?

This is calculated as:

1 lot = 1 house

Hence:

9 house = 9/10 acres

1 house = x

Cross Multiply

9x = 9/10 acres

x = 9/10 ÷ 9

x = 9/10 × 1/9

x = 1/10 acres

Hence, the size of each lot when divided equally = 1/10 acres

Answer:

20%

Step-by-step explanation:

Here, we want to calculate the percentage increase in the price of a can of green beans

Mathematically, we use the formula below;

(new price - old price)/old price * 100%

From the question;

old price = $0.50

new price = $0.60

So we have;

(0.6-0.5)/0.5 * 100%

= 0.1/0.5 * 100%

= 20%

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A bakery sells 44 large boxes of muffins and 50 small boxes of muffins in one day. Each large box holds 20 muffins, and each small box holds 15 muffins.

The total number of muffins sold on this day will be calculated as,

⇒ 44 x 20 + 50 x 15

⇒ 880 + 750

⇒ 1,630

The total number of muffins sold on this day will be 1,630.

Mean allowance of the given students is equals to $13.

" Mean is defined as the ratio of the sum of all the given number to the  total number of numbers. It is also known as average."

Formula used

Mean = [tex]\frac{Sum of all the given numbers}{Total number of numbers}[/tex]

According to the question,

Number of students = 10

Weekly allowances of each student

= $9, $11, $13, $15, $20, $10, $12, $15, $10, $15

Substitute the value in the formula of mean we get,

mean = [tex]\frac{9+11+12+13+20+2(10)+3(15)}{10}[/tex]

         [tex]= \frac{130}{10}\\ \\= 13 dollars[/tex]

$14.99

$16.49

Answer:

See explanation

Step-by-step explanation:

Based on the information provided, there is a proportional relationship between the cost of the apples and the weight of the apples as well as between the number of toppings and the cost of the pizza.

We know that there is a proportional relationship when there is a linear increase  or decrease in the two quantities in the relationship. This increase or decrease is usually by a constant value.

In the relationship between the weight of apples and the cost of apples, the cost of apples increases steadily by $1.88 which shows a proportional relationship.

Also, in the relationship between the number of toppings and the cost of pizza, the cost of pizza increases by $1.5 which shows a proportional relationship between the two.

Answer:

  32.4 feet

Step-by-step explanation:

The applicable relationship between angle and triangle lengths is ...

  Sin = Opposite/Hypotenuse

The dock height is the side of the triangle opposite the given angle. The desired length is the hypotenuse of the triangle, so we have ...

  sin(18°) = (10 ft)/s

  s = (10 ft)/sin(18°) = (10/0.30902) ft

  s ≈ 32.4 ft

The length of the rope is about 32.4 feet.

Option D

Step-by-step explanation:

She is selling tickets for $10 each, and if 1,007 people attended, that would be: $10,070 in proceeds. So, you then subtract that from the balance at the bank: -$3,200.

-$3,200 + $10,070 = $6,870 balance.

Answer:

Step-by-step explanation:

This question is a bit sloppy. In higher math courses it would not be permitted. I'll give you the general rule that applies to this question -- sort of.

If you have a triangle that hast angles of 100 50 and 30

The largest side will be opposite the 100 degree angle.

The smallest side will be opposite the 30 degree angle.

So for the question, you are intended to say that CD > AB because CD is opposite a 43 degree angle and AB is opposite a 40 degree angle.

So the answer is Since 43 > 40 then CD>AB
