Sevati has 18 magazines in her collection. Sevati's collection of periodicals is represented by the phrase x - 7 = 25.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.  Let's examine the writing of expressions. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases.

given

If x is the alita collection,

then sevati is equal to x - 14 + x = 50.

Sevati's collection of magazines is represented by the formula 2x - 14 = 50, hence the alita collection is equal to 2x = 36

x = 18

Answer:

1/30 of a mile per minute.

Step-by-step explanation:

8/4 = 2 miles per hour.

2/60 = 1/30 of a mile per minute.

The original price of each notebook is $5.5

Trace is purchasing some notebooks

Each notebook is $2 off the original price

He buys 8 notebooks for $28

The first step is to calculate the price of one notebook

8= 28

1= x

Cross multiply both sides

8x= 28

x= 28/8

x= 3.5

1 notebook is $3.5

$2 was removed from the initial price. Therefore the original price is

2 + 3.5

= 5.5

Hence the original price of the notebook is $5.5

5a) The total cost of buying the car, including the harmonized sales tax (HST) of 13%, is $36,160.

5b) Under the lease, the customer saves $14,760.

5c) The lessee after returning the car has the following lease options:

6a) The after-tax cost of the car that Jordan wants to buy is $32,199.35.

6b) The part of the Honda Civic that needs to be financed after the down payment is $26,199.35.

6c) The monthly payment will be $567.26.

6d) After four years, the total amount Jordan had paid for the vehicle is $33,228.48.

A lease is a financing option for the use of capital assets by which the lessee utilizes an asset for a stated period while making periodic payments to the lessor.

A car purchase can also be financed through loans, like home mortgages.

Value of the car = $32,000

Harmonized Sales Tax (HST) = 13%

Cost of the car with HST = $36,160 ($32,000 x 1.13)

Down payment = $1,000

Financing part = $35,160 ($36,160 - $1,000)

Installment payments = 48

Periodic payments = $425

Total lease cost = $21,400 ($1,000 + 48 x $425)

Savings from leasing = $14,760 ($36,160 - $21,400)

The value of the Honda Civic = $28,495

Harmonized Sales Tax (HST) = 13%

After-tax cost = $32,199.35 ($28,495 x 1.13)

Annual interest rate = 1.9% compounded monthly

Down payment = $6,000

Financing part = $26,199.35 ($32,199.35 -$6,000)

Financing period = 4 years

N (# of periods) = 48 months (4 years x 12)

I/Y (Interest per year) = 1.9%

PV (Present Value) = $26,199.35

FV (Future Value) = $0

P/Y (# of periods per year) = 12

C/Y (# of times interest compound per year) = 12

Results:

Monthly Payments (PMT) = $567.26

Sum of all periodic payments = $27,228.48

Total Interest $1,029.13

Total amount paid by Jordan after 4 years = $33,228.48 ($27,228.48 + $6,000)

Step-by-step explanation:

By using the definition of vertical angles, we will see that the correct option is B, the measure of the other angle is 95°.

We define by vertical angles as angles that share a vertex and are in opposite sides of the two intersecting lines that form that vertex.

Vertical angles always have the same measure, in this particular case, we know that one of the vertical angles has a measure of 95 degrees, then the other vertical angle (whose measure we want to find) will also be 95 degrees, just by definition of vertical angles.

In that way, we conclude that the correct option is B: 95°

Answer:

There will be 5 roses.

Step-by-step explanation:

Let r = the number of roses.

Total cost =

numberof Roses × price per rose AND cost of vase

Total at Kingwood's

= 1r + 20

Total at Anita's

= 3r + 10

We are looking for r (the number of roses) when the totals at either place are the same.

Set them equal to each other.

1r + 20 = 3r + 10

Subtract 1r.

20 = 2r + 10

Subtract 10.

10 = 2r

Divide by 2.

10/2 = r

5 = r

When Elijah buys 5 roses, the cost is the same at either florist.

Check:

at Kingwood's

= 1r + 20

= 1(5) + 20

=25

At Anita's

= 3r + 10

= 3(5) + 10

= 15 + 10

= 25

5 roses costs $25 at either florist.

The number of yards of rope she can make for the step is 3 yards

From the question, we have the following parameters that can be used in our computation:

Yards of rope per step = 1/2 yards per step

Total number of steps = 6 steps

The number of yards of rope she can make for the step can then be calculated using the following equation

The number of yards of rope = Total number of steps * Yards of rope per step

Substitute the known values in the above equation, so, we have the following representation

The number of yards of rope = 1/2 * 6

Answer:

(k+3)(k+3) + (k-9)(k-9), or p = (k+3)^2 + (k-9)^2, or p = 4k^2 - 24k + 180

Step-by-step explanation:

A rectangle has four sides, two sides both have equal width, while the other two have equal length. The perimiter is the total sum of these sides. We can use the following equation to represent the perimiter using the width and length:

p = 2w + 2l

We know that the width equals (k+3)(k+3), so 2w would equal 2(k+3)(k+3). In the form of a quadratic equation, this would equal 2k^2+12k+18.

We also know that the length equals (k-9)(k-9), so 2l would equal 2(k-9)(k-9). As a quadratic equation, this would equal 2k^2-36k+162.

Plugging these values into our equation we get:

p = (k+3)(k+3) + (k-9)(k-9), or p = (k+3)^2 + (k-9)^2.

Or in the form of a quadratic equation:

p = 2k^2 + 12k + 18 + 2k^2 - 36k + 162

=

p = 4k^2 - 24k + 180

Hope this helps!

The perimeter of the rectangle can be calculated using the formula 2(length + width). Substituting the given expressions for length and width, we get 2[(k+3)(k+3)+(k-9)(k−9)]. This simplifies to the expression 4k^2-24k+180.

The perimeter of a rectangle is calculated by adding the lengths of all its sides. With the width given as (k+3)(k+3) centimeters, and the length as (k-9)(k−9) centimeters, we can substitute these into the formula for the perimeter of a rectangle, which is 2(length + width).

Therefore, the expression representing the perimeter of the rectangle is 2[(k+3)(k+3)+(k-9)(k−9)]. This simplifies to 2[(k^2+6k+9)+(k^2-18k+81)], which further simplifies to 2[2k^2-12k+90], and ultimately simplifies to 4k^2-24k+180.

The difference between Mary's weight when she was 10 year's old and when she was born will be;

⇒ 72 pounds

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

When Mary was born, she weighed 8 pounds.

And, When she was 10 years old, she weighed 10 times as much.

Now,

Since, When she was 10 years old, she weighed 10 times as much.

Hence, When she was 10 years old, she weighed = 10 × 8 pounds

                                                                             = 80 pounds

And, When Mary was born, she weighed 8 pounds.

Thus, The difference between Mary's weight when she was 10 year's old and when she was born is,

⇒ 80 - 8 pounds

⇒ 72 pounds

So, The difference between Mary's weight when she was 10 year's old and when she was born is 72 pounds.

The height of the rock ledge is 20 meters and height of the tree is 59 meters.

Heights and Distances is a study about the applications of Trigonometry. It has many real-life applications, such as measuring the object’s height, depth of the object, the distance between two celestial objects etc. The formulas and the ratios of trigonometry are helpful in the study of heights and distances.

From a rock ledge, the angle of elevation to the top of a tree is 22°. The angle of depression to the base of the tree is 12°.

a) Let the height of the rock ledge be x.

Now, tan12°=x/96

0.2125=x/96

x=20.4 meters

x≈20 meters

b) Let the height of the tree be y

Here, part of the tree is y-20
