The following rectangle has a length of 6 centimeters and an unknown width. If the
perimeter is 21 centimeters, what is the width of the rectangle? Set up an equation, and solve.

Answers

Answer 1

Answer:

The width is 4.5 cm

Step-by-step explanation:

w + w+ 6 + 6 = 21  Combine like terms

2w + 12 = 21  Subtract 12 from both sides

2w = 9  Divide both sides by 2

w = 4.5

The increase in the money supply that causes prices to rise and leads to inflation, loses purchasing power.

What is inflation?

Inflation refers to the persistent rise in the general prices of commodities in the economy over a period of time. If the prices of goods and services increase in an economy without an increase in income of people, it reduces the purchasing power of individuals.

This follows the law of demand which states that; the higher the price, the lower the quantity demanded; the lower the price, the higher the quantity demanded.

is located at the point (-5, 7) and Ca'Miyah's house is
located at (-2, 3). To the nearest tenth, How far is it
from Jordan's house to Ca'Miyah's house?
(51)

Answers

Answer: 5.2

Step-by-step explanation:

If we put both points on a grid, Jordan's house would be 4 points above and 3 points to the left of Ca'Miyah's. We can plug these two amounts into the pythagorean theorem to find the distance between the houses: 4^2 + 3^2 = x^2. If we solve this equation, we get 5.196, which rounds to 5.2.

Domain: [tex]x > -5[/tex] or [tex](-5,\infty)[/tex]

Range: [tex]y\geq -3[/tex] or [tex][-3,\infty)[/tex]

Step-by-step explanation:

The domain is essentially the set of x-values in a given graph. In this graph. we see that the lowest x-value is an unfilled dot when x=-5. The unfilled dot means that the function [tex]f(x)[/tex] doesn't include -5. We then see that the x-value goes to positive infinity. This means that [tex]x[/tex] must be greater than -5. It is not greater or equal to -5 because the dot is not filled.

Therefore, we have that [tex]x > -5[/tex]. To convert to interval notation we can take the lower value (-5) and put it on the left side and put the higher value ([tex]\infty[/tex]) and put it on the right side. Since the graph doesn't include -5, we can put parentheses around both values to get [tex](-5,\infty)[/tex].

Note: We always put parentheses around both [tex]\infty[/tex] and [tex]-\infty[/tex].

The range is basically the same as the domain but with the y-value. We can see that the lowest y-value is y=-3. This includes -3 since the line fills the point in. Then we see that the highest y-value is once again positive infinity. This means that [tex]y\geq-3[/tex].

Now when we convert to interval notation, we have -3 and [tex]\infty[/tex]. This time since y=-3 is included in the function, we put a hard bracket around -3. Thus, we get [tex][-3,\infty)[/tex].

The final length of Juanita recording after editing was completed was 7/6

To solve this exercise, we have to state the equation using the information of the problem:

Transforming the mixed number to fraction, we get:

What is the solution to the compound inequality?

Given the data in the question;

-x - 8 ≤ -15 and -18 ≤ -x - 8

To solve, simplify the first part of the inequality by solving for x.

-x - 8 ≤ -15

Add 8 to both sides

-x - 8 + 8 ≤ -15 + 8

-x ≤ -7

Divide both sides by -1

Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.

-x/-1 ≥ -7/-1

Next, simplify the second part of the inequality by solving for x

-18 ≤ -x - 8

Rewrite as

-x - 8 ≥ -18

Add 8 to both side

-x - 8 + 8 ≥ -18 + 8

-x ≥ -10

Divide both sides by -1

Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.

The difference of two natural number is 2. The sum of their squares is 100.Find the numbers.

Answers

The required two numbers are 6 and 8.

Let us denote the required numbers by c and d.

Given that the difference between two natural numbers is 2.

If we assume d > c, then d – c = 2

⇒ d = 2 + c → equation 1.

Also given that the sum of their squares is 100.

⇒ c² + d² = 100

⇒ c² + (2 + c)² = 100 (using the value of d from equation 1)

⇒ 2c² + 4c + 4 = 100

⇒ 2c² + 4c = 96

⇒ 2c(c+2) = 96

⇒ c(c+2) = 48

Using the factorization for 48, we get 6 × 8 = 48

⇒ c = 6

⇒ c+2 = 8

⇒ d = 8

Therefore, the required two numbers are 6 and 8.

Add the 55 degrees and the already existing right angle to get 145. Since you are trying to find the value that equals 180, subtract 145 from 180 to get 35.

2x + 3y = 1200, 3x + 2y = 1300. what is the value of 5x + 5y using substitution method​

Answers

The value of 5x + 5y is 2500 by substitution method.

According to the given question.

We have two equations

2x + 3y = 1200

3x + 2y = 1300

Since, we have to find the value of 5x + 5y by substitution method.

From equation 2x + 3y = 1200

2x = 1200 - 3y

⇒ x = [1200 -3y]/2

Substitute the value of x in 3x + 2y = 1300.

⇒ 3[1200 - 3y]/2 + 2y  = 1300

⇒   3[600 -3y/2] + 2y = 1300

⇒ 1800 - 9y/2 + 2y  = 1300

⇒ 1800 + (4y - 9y)/2  = 1300

⇒ (4y - 9y)/2  = -500

⇒ -5y = -1000

⇒ y = 200

So,

x = [1200 - 600]/2  = 600/2 = 300

Thereofore, the value of 5x + 5y by substitution method is given by

5(300) + 5(200)

= 1500 + 1000

= 2500

Hence, the value of 5x + 5y is 2500 by substitution method.
