The process of finding the value of a numerical or algebraic expression is called evaluation.

Evaluation involves substituting the given values of the variables in the expression and then simplifying the expression using the order of operations (PEMDAS).

For example, if we are asked to evaluate the expression 3x + 2y when x=4 and y=5, we would substitute these values to get 3(4) + 2(5), which simplifies to 12 + 10 = 22. Therefore, the value of the expression 3x + 2y when x=4 and y=5 is 22.

In algebra, evaluation is an important process because it allows us to find the value of an expression for specific values of the variables, which can help us to solve equations or inequalities, and to simplify expressions.

Answer:

The shirt costs $21

Step-by-step explanation:

2x + 3y = 127    ....eq 1

Her twin sister Hallie bought 1 pair of jeans and 4 shirts for $116.

So, x + 4y = 116     ....eq 2

Multiplying eq 2 by 2, we get :

2x + 8y = 232     ....eq 3

Subtracting eq 1 by eq 3, we get :

(2x + 8y) - (2x + 3y) = 232 - 127

5y = 105

Thus, y = 21

Putting this value of y in eq 2, we get :

x + 4(21) = 116

x = 116 - 84 = 32

Therefore, the cost of a pair of jeans = x = $32

And the cost of a shirt = $21

The scale floor's perimeter is 34 inches.

To solve, we can set up fractions:

21/7 = 30/x

Cross multiply and you get:

21x = 210

Divide each side by 21:

x = 10

You can apply the following equation since you're attempting to determine the floor's perimeter:

2w + 2l = p

Substitute to solve:

2 ( width = 10 )

2 ( length = 7 )

2 (7) + 2 (10) = p

14 + 20 = p

34 = p

Jet could fly a distance of 752 miles in 8 hours if it travels at the same rate.

Speed is defined as the unit rate in terms of distance travelled and the time taken to travel the distance.

Speed has only magnitude and no direction and therefore is a scalar quantity.

Given that,

a jet travels 470 miles in 5 hours.

Distance travelled = 470 miles

Time taken to travel the distance = 5 hours

Speed of the jet = 470 miles / 5 hours = 94 miles per hour

Given that jet is travelling at the same rate. So the speed is constant.

We have to find the distance travelled in 8 hours.

Let d be the distance.

Speed = Distance / Time

Distance = Speed × Time

d = 94 × 8

d = 752 miles

Hence the distance travelled is 752 miles in 8 hours.

The missing angle measures are:

m∠H = m∠C = 83 degrees

m∠C = 83 degrees

m∠F = m∠A = 22 degrees

m∠G = m∠B = 75 degrees

m∠H = m∠C, since they are corresponding angles, but we still need to find the measure of m∠C.

m∠A + m∠B + m∠C = 180 degrees

The difference in housing prices in the fifth year is $7,125.

Price is the amount of money one has to pay for goods or services. It is also the return on an investment or the cost of borrowing money. Price is determined by the supply and demand of a product or service. It is also influenced by market forces such as competition, production costs, and availability of resources. Price is a key factor in determining the success of a business, as it can affect consumers' buying decisions and profitability.

$M(5) - G(5) = (1.7(5)³- 6.5(5)²+ 212) - (1.6(5)²- 14(5) + 165) = $7,125

As per the concept of average, the cost of producing 6,000 units is $79,200.

The average, also known as the mean, is a mathematical representation of a set of data. It is calculated by adding all the values in the set and dividing the result by the number of values in the set.

When it comes to calculating the total amount of direct manufacturing cost incurred when 6,000 units are produced, it is important to use the average cost per unit. To do this, we need to multiply each average cost per unit by the number of units produced.

The total direct manufacturing cost incurred can be calculated as follows:

Direct materials = $5.20 * 6,000 = $31,200

Direct labor = $3.75 * 6,000 = $22,500

Variable manufacturing overhead = $1.65 * 6,000 = $9,900

Fixed manufacturing overhead = $2.60 * 6,000 = $15,600

The total direct manufacturing cost incurred is $79,200.

The equation of circle is ( x + 1 )² + ( y - 2 )² = 20

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the points on the circle be A ( -5 , 4 ) , B ( 3 , 4 ) and C ( 3 , 0 )

Now , the equation of the circle is of the form

ax + by + c = x² + y²

Substituting the values in the equation , we get

-5a + 4b + c = 41   be equation (1)

3a + 4b + c = 25   be equation (2)

3a + c = 9   be equation (3)

Subtracting equation (2) from equation (1) , we get

-8a = 16   be equation (4)

Divide by -8 on both sides of the equation , we get

a = -2

Substitute the value of a in equation (3) , we get

3 ( -2 ) + c = 9

-6 + c = 9

c = 15

Substitute the value of a and c in equation (2) , we get

-6 + 4b + 15 = 25

4b + 9 = 25

4b = 16

b = 4

So , the value of a , b and c are -2 , 4 and 15 respectively

Now , the equation of circle will be

-2x + 4y + 15 = x² + y²

On simplifying the equation , we get

x² + y² + 2x - 4y - 15 = 0

( x² + 2x + 1 ) - 20 + ( y² - 4y + 4 ) = 0

So , the equation will be

( x + 1 )² + ( y - 2 )² = 20

Hence , the equation of circle is ( x + 1 )² + ( y - 2 )² = 20

What is Compound Interest ?

Compound interest is a method of calculating interest on a loan or investment, where interest is earned on both the initial principal amount and on any interest that has already been earned. In other words, interest is added to the principal, and then interest is calculated on the new total amount (the principal plus the previously earned interest). This results in the interest earned growing exponentially over time.

According t o given condition :

To calculate the amount Ann will owe after 6 years, we can use the formula for compound interest:

A = P(1 + r/n)^(n*t)

where:

A = the amount Ann will owe after 6 years

P = the initial principal amount borrowed, which is $8000 in this case

r = the annual interest rate as a decimal, which is 15% or 0.15

n = the number of times interest is compounded per year, which is once annually in this case

t = the number of years, which is 6 in this case

Plugging in these values, we get:

A =

A =

A = $15,258.23

Therefore, Ann will owe $15,258.23 after 6 years, assuming she makes no payments.
