Find the measure of the missing angles?

The sale price of the shirt can be found by calculating 30% of the original price, which in this case would be $22.40 x 0.30 = $6.72. Thus, the sale price of the shirt would be $22.40 - $6.72 = $15.68.

Answer:

11 inches

Step-by-step explanation:

4x + x = 55    Combine like terms

5x = 55     Divide both sides by 5

x = 11  This is the length of the shortest piece the other piece is 44 4(11)

Answer:

11 inches, 44 inches

Step-by-step explanation:

First of all, we need to make this equation, into an algebraic one:

4x + x = 55

The x represents the number of inches for the rope.

Now you simplify:

5x = 55

This equation can be simplified to a regular division problem:

55/5 = x

Using basic division, x is equal to 11 inches.

Now, this is just the shorter rope.

Note that the other piece is 4 times larger than the short one:

4 x 11 = 44

Thus 11 inches and 44 inches is the answer

The algebraic expression 18n - 45 is correct for the statement "45 less than the product of 18 and a number written as an algebraic expression"

We can represent an unknown number using letters and then carry out basic mathematics operations to get the value of the unknown number.

Let us represent the unknown number with the letter "n"

The product of 18 and the number will be;

18 × n = 18n

45 less than the product of 18 and the number (n) is thus written algebraically as;

18n - 45

Therefore, 45 less than the product of 18 and a number(n) is written as an algebraic expression as 18n - 45.

hopes this helps please mark brainliest

Answer:

D

Step-by-step explanation:

Based on the information provided, it appears that the correct answer would be option D: y=2 - 15x. This can be determined by solving the given equation for y by isolating the y-term on one side of the equation. To do this, you can subtract 15x from both sides of the equation, resulting in y = 2 - 15x.

Here is the complete process for solving the equation:

Begin by subtracting 15x from both sides of the equation:

15x + 3y = 2

-15x -15x

This simplifies to:

3y = 2 - 15x

Now, divide both sides by 3 to isolate the y-term:

3y/3 = (2 - 15x)/3

This simplifies to:

y = 2/3 - 15x/3

Finally, since 3 is a common factor, we can simplify the right side of the equation further by dividing both the numerator and the denominator by 3:

y = 2/3 - 15x/3

y = (2/3) / (3/3) - (15x/3) / (3/3)

y = (2/3) / 1 - (15x/3) / 1

y = 2/3 - 15x/3

y = 2/3 - 5x

Therefore, the equivalent equation is y = 2/3 - 5x, which is option D.

After solving the equation the value of F = (3GR -G - 8S) / 5S

Define Algebraic Expression

In mathematics, an expression that includes variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.)

Given expression is,

5F + 8 / G = 3R - 1 / S

Multiply both side by G

( 5F + 8 / G ) * G= (3R - 1 / S) * G

Simplify it,

5F + 8 = G(3R - 1) / S

Now, solve for F

5F = (3GR - G / S )- 8

5F = 3GR - G - 8S / S

F =  3GR - G - 8S / 5S

Hence, After solving the equation the value of F = (3GR -G - 8S) / 5S

The distance between the cars after a hour is 14 meters.

Speed is the rate at which an object's location changes in a particular direction. The distance traveled on relation changes to a particular direction. The distance in relation to the time it took to travel the distance is the speed. It's a scalar quantity.

In this case, the cars leave town at the same time. One travels west at 56 mph, and the other travels south at 42 mph.

With the speed, the total distance after an hour will be:

The selling price of a used book at the store where the owner buys a used book for $1.50 and resells the used book at a price of 400% the price at which he buys the used book is $6.00

The selling price of an item is the price which is displayed on the item on the shelves of a store. The selling price is often different from the price at which the item is bought, or produced, which is often lesser than the price at which the item is sold.

The amount at which the owner buys each used books = $1.50

The amount at which the owner of the used book store sells the books = 400% of the amount he paid for the books

400% of an amount x is equivalent four times the amount. (4 × x)

The price at which the owner sells a used book at his store, P, is therefore;

P = 400% × $1.50 = 400/100 × $1.50 = $6.00

The measure of three angles of triangle are 45°, 55° and 80°.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Let the smallest angle of triangle be x.

One angle the triangle measures 10° greater the smallest angle, that is x+10°

The third angle measures 10° less than twice the smallest angle.

The third angle is 2x-10°

Now, x+2x-10°x+10°=180°

⇒ 4x=180°

⇒ x=45°

So, 2x-10°=80° and x+10°=55°

Therefore, the measure of three angles of triangle are 45°, 55° and 80°.

What is the greatest common factor (GCF)?

A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common. For instance, the numbers 12, 20, and 24 share the components 2 and 4. Since four is the largest, we refer to the GCF of 12, 20, and 24 as four. Frequently, GCF is used to identify common denominators.

We have,

0.245

Write 0.245 as  

0.245 / 1

Multiply both the numerator and denominator by 10 for each digit after the decimal point.

0.245/1

=   0.245 x 1000 / 1 x 1000

=  245 / 1000

In order to reduce the fraction find the Greatest Common Factor (GCF) for 245 and 1000. Keep in mind a factor is just a number that divides into another number without any remainder.

The factors of 245 are: 1  5  7  35  49  245

The factors of 1000 are: 1  2  4  5  8  10  20  25  40  50  100  125  200  250  500  1000

The Greatest Common Factor (GCF) for both 245 and 1000 is: 5

Now to reduce the fraction we divide both the numerator and denominator by the GCF value.

245/ 1000

= 245 ÷ 5 /1000 ÷ 5

=  49 / 200

The decimal part is: 0.245 = 245/1000
