Given:

Amount of bill = $25

Coupon = 15% off

Tip = 20% after discount is applied.

To find:

The total that Dylan's mom will pay at the restaurant.

Solution:

We have,

Amount of bill = $25

Discount = 15%

Amount after discount = 25 - 15% of 25

                             [tex]=25-\dfrac{15}{100}\times 25[/tex]

                             [tex]=25-3.75[/tex]

                             [tex]=21.25[/tex]

So, amount after discount is $21.25.

Tip = 20%

Total Amount = Amount after discount + Tip

[tex]\text{Total Amount}=21.25+\dfrac{20}{100}\times 21.25[/tex]

[tex]\text{Total Amount}=21.25+4.25[/tex]

[tex]\text{Total Amount}=25.5[/tex]

Therefore, Dylan's mom will pay total $25.5 at the restaurant.

Step-by-step explanation:

soln

given

y=2x+3 -----(i)

y=-x-9 ------(ii)

now, putting value of equation (i) in (ii)

y= -x-9

or, 2x+3 = -x-9

or, 2x+x = 9-3

or, 3x = 6

or, x = 6/3

or, x = 2

again,

y = 2x+3

or, y = 2×2+3

or, y = 7

therefore, value of X and Y are 2 and 7 respectively.

Answer:

The constant of variation 'k' is NOT constant.

Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.

Step-by-step explanation:

Given the table

Number of Lawns         1           2            3              4

Amount Earned ($)      16         32          54            72

We know that when y varies directly with x, we get the equation

y ∝ x

y = kx

k = y/x

where 'k' is called the constant of proportionality.

In our case, the 'Amount earned ($) ' is represented by 'y', and the 'Number of Lawns' is represented by 'x'.

Let us check the constant of proportionality using the equation

k = y/x

k = 16/1 = 16

k = 32/2 = 16

k = 54/3 = 18

k = 72/4 = 18

It is clear that that the constant of variation 'k' is NOT constant.

Therefore, we conclude that Taylor did not charge a constant rate. The rates are not equal because his rate changed.

4x

Step-by-step explanation:

you have 3 of x and add another x to get 4 of x

Answer:

4x

Step-by-step explanation:

everytime the variable is alone it stands for 1 so,

x is the same as 1x it's invisible 1 so no one puts it so,

3x + x is the same as 3x + 1x = 4x.

Answer:

16.75 meters

Step-by-step explanation:

This problem is a plug in problem.

H = 0.20x + 12.75

we plug in 20 for x which gives us

(0.20 * 20) + 12.75

which equals

4 + 12.75

giving us

16.75 meters

Answer:

16.75 meters

Step-by-step explanation:

First of all, in this x=20

let's plug it in

y=0.20×20+12.75

y=4+12.75

y=16.75

Answer:

Equation → 5y = 3y + 6

Value of ST = 15

Step-by-step explanation:

From the picture attached,

In right triangles ΔVST and ΔVUT,

Acute angles ∠SVT ≅ ∠UVT [Given]

TV ≅ TV [By reflexive property of congruence]

ΔVST ≅ ΔVUT [Hypotenuse angle congruence of right triangles]

Therefore, corresponding parts of the congruent triangles are congruent.

Therefore, ST ≅ TU

5y = 3y + 6

5y - 3y = 6

2y = 6

y = 3

Therefore, ST = 5y

ST = 5(3)

     = 15

Answer:

94.99 - 23.7475 = 71.24 dollars.

Step-by-step explanation:

Answer: Yes

Step-by-step explanation:

From the question, we are informed that a survey was conducted of 880 college students attending the same university and that they were offered a list of 10 different internet service providers and were asked to select the one they prefer.

Basee on this information, if everyone selected equal numbers, each service provider will get (880 / 10 = 88 students). In this case, if someone has 89 votes, this means that another person will get 87 votes while the remaining 8 service providers gets 88 students each. Therefore, the device provider with 89 votes can come out on top.

y=3x-20 thats ur answer good luck

Answer:

It will take them 20 years to make the same salary

Step-by-step explanation:

Let us solve the question

Assume that they will have the same salary after x years

∵ Alex makes $30,000 a year at his job

∵ He gets a $2,500 a year raise every year

∵ He will work x years

→ That means his salary is the sum of a fixed amount and the raise times x

∴ His salary = 30000 + 2500(x) ⇒ (1)

∵ Sydney makes $40,000 a year

∵  He gets a $2,000 raise every year

∵ He will work x years

→ That means his salary is the sum of a fixed amount and the raise times x

∴ His salary = 40000 + 2000(x) ⇒ (2)

∵ They will make the same salary after x years

→ Equate (1) and (2)

∴ 30000 + 2500x = 40000 + 2000 x

→ Subtract 30000 from both sides

∴ 2500x = 2000x + 10000

→ Subtract 2000x from both sides

∴ 500x = 10000

→ Divide both sides by 500

∴ x = 20

∴ It will take them 20 years to make the same salary

Answer: 254, 255, 256

Step-by-step explanation:

Divide the total by 3 to get the integer in the middle. 255.

Subtract 1 to get the first integer, 254.

Add 255 + 1 to get the third integer, 256.

Answer:

The greatest common factor in that expression is 3x², giving you the expression:

3x²(-x² + 4x -7)

Step-by-step explanation:

All three terms are divisible by three:

3(-x⁴ + 4x³ - 7x²)

Each term is also divisible by x²:

3x²(-x² + 4x -7)

So the greatest common factor is 3x²

Answer: Infinite solutions

Step-by-step explanation:

This is because they're the same and will have the same points till the line ends.

It's when the equations intersect at a point that they have one solution.

When the lines a parallel, they have no solutions.

Answer:

5. There were 30 students in that class.

6. Drew weighed 245 pounds at the start.

Step-by-step explanation:

5. Since 3 students are absent in which represents 10% of the classroom, multiply the number 3 by 10 to get 30 students which represents the full roster.

6. 20% of his original weight is 49, multiply that number by 5 to get the original weight which is 245 pounds.

Answer:

5. 3 / 0.1 = 30 students

6. 49 / 0.2 = 245 lbs

Answer:

3)

Step-by-step explanation:
152 - 90 = 62

180-152 = 28 which <CED and <BAC = 28.
180-28-43 = 109

<ACD = 71 because if  <ACB = 109. then think of DCB as a 180 degree. 180-109. then it is 71.
