Answer:

The original price was $875.

Step-by-step explanation:

a = p * w

630 = 72% * w

630 / 0.72 = $875

$875 should be the original price, I hope this helps!

Answer:

16.39

Step-by-step explanation:

Solution 1: You can turn the words into Algebra so What (x) is(=) 1.10 of (multiply)14.9, So x = 1.10 (14.9). x= 16.39

When you see the word what, place an 'x', is means '=', 110% = 1.10

Solution 2: Notice how 100 percent is already 14.9 so 110% should be greater than 14.9, so we're missing another 10%, and 10% of 14.9 is 1.49 just by moving the decimal over.  So you would need 14.9 + 1.49 more, so a total of 16.39.

Answer:

-25 and -4

Step-by-step explanation:

to solve this, you need to use the sum product pattern. this means you're going to take the x factor, 29x and separate it into it's squares.

(x^2+25x)+(4x+100)

then you take out the common factor in each separated equation

x(x+25)+4(x+25)

you see that the items in the parentheses are the same, this means that this is one of the equations you will use when factoring. the rest of the equation that is left out (the common factors) is the other equation

(x+25)(x+4)

to get the zeroes, you set each equation equal to zero and solve

x+25=0           x+4=0

x= -25             x= -4

Answer:

When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative.

Step-by-step explanation:

Answer:

1. 9 = x

2. y = 2

Just copy these steps on paper, then submit.

Writing it yourself will help you, trust me :)

1. 2(x + 5) = 3x + 1

2(x + 5) = 3x + 1

Distribute the 2

2x + 10 = 3x + 1

-1                    -1

2x + 9 = 3x

-2x         -2x

9 = x

2. 3y - 4 = 6 - 2y

3y - 4 = 6 - 2y

     +4    +4

3y = 10 - 2y

+2y       +2y

5y = 10

Divide both sides by 5

y = 10/5

y = 2

Answer:

When x is equal to 1, y is equal to 18-2(1), which is equal to 16.

When x is equal to 2, y is equal to 18-2(2), which is equal to 14.

When x is equal to 4, y is equal to 18-2(4), which is equal to 10.

When x is equal to 5, y is equal to 18-2(5), which is equal to 8.

Let me know if this helps!

You can solve this by doing Pythagorean theorem. I think thats what its called... a^2+b^2=c^2. So 24 squared plus 18 squared is 900. The square root of 900 is 30. The legnth of the third side is 30.

The distance from the top of the flagpole to the ground is 30 feet.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.

Given the distance from the base of a flagpole to a point on the ground = 24 feet

height of flagpole = 18 feet

the distance from the top of the flagpole to the ground is x

by Pythagorean theorem, we can find the distance

h² = b² + p²

h = hypotenuse = x

b = base = 24 feet

h = height = 18 feet

x² = 24² + 18²

x² = 576 + 324

x = √900

x = 30 feet

Hence the value of x is 30 feet.

Answer:

D the slope is undefined and the y intercept is -5

Step-by-step explanation:

quadrant II and III are on the left. the only way for a line to pass through those two quadrants without passing through I and I would have to be a negative x intercept. The slope would have to be undefined which would make a diagonal line. if the slope was 1 or anything higher it would end up hitting the other quadrants.

Answer:

k = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Given that r varies directly as p then the equation relating them is

r = kp ← k is the constant of variation

To find k use the condition r = 3 when p = 15, then

3 = 15k ( divide both sides by 15 )

[tex]\frac{3}{15}[/tex] = k , that is

k = [tex]\frac{1}{5}[/tex]

Answer:

Adult ticket is $6

Student ticket is $4, as you said.

Step-by-step explanation:

We'll call adult tickets x and student tix y.

14x + 11y = 128

14x + y = 88

First, solve the second equation for y in terms of x:

y = 88- 14x

Then substitute that for y into the first equation:

14x + 11(88-14x) = 128

14x + 968 - 154x = 128

-140x = -840

x = 6  The adult ticket is $6, like you said.

Now take that and solve for y:

y = 88 - 14(6)

y = 88 - 84

y = 4 The student ticket is $4, as you said.

Hope this helps. Feel free to ask questions so you can understand.

Answer:

17, 19, 21

Step-by-step explanation:

let the 3 consecutive odd numbers be n, n + 2 and n + 4 , then

3n = 2(n + 4) + 9 ( 3 times smallest is 9 more than twice the largest )

3n = 2n + 8 + 9

3n = 2n + 17 ( subtract 2n from both sides )

n = 17

n + 2 = 17 + 2 = 19

n + 4 = 17 + 4 = 21

The 3 numbers are 17, 19, 21

Answer:

y=7x-6

Step-by-step explanation:

You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say

y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.

profit %=?

Step-by-step explanation:

The profit percentage is 4% .

Profit percentage (%) is the amount of profit expressed in terms of percentage. This profit is based on the cost price .

Formula for profit percentage is:

(Profit/Cost Price) × 100

where,

Profit = Selling price - Cost price

According to the question

Let Cost price of the article = 100x

marked price is 30% above the cost price

i.e  marked price = [tex]\frac{130}{100} * 100x[/tex]

                            = 130 x

selling price of an article is 20% less than its marked price

i.e Selling price of the article = [tex]130x * \frac{100-20}{100}[/tex]

                                                = [tex]130x * \frac{80}{100}[/tex]

                                                = 104 x

Now ,

Profit = Selling price - Cost Price

Profit = 104x -100x

Profit = 4x        

Profit percentage =   [tex]\frac{Profit}{Cost PRice} *100[/tex]

substituting the values in formula

Profit percentage =  [tex]\frac{4x}{100x} *100[/tex]

Profit percentage =  4%

Hence, the profit percentage is 4% .
