Answer:

A or B

Step-by-step explanation:

Answer:

Step-by-step explanation:

let the number of children be x

and the number of adults be y

so

7x+12y=236-----1

and

14x+7y=217------2

equating both 1 and 2 we have

7x+12y=236-----1

14x+7y=217------2

multiply 1 by 2

subtract 2 from 1 we have

  14x+24y=472-----3

 - 14x+7y=217------2

    0x+17y=255

17y=255

y=255/17

y=15

put y=15 in eqn 1 we have

7x+12y=236-----1

7x+12*15=236-----1

7x+180=236-----1

7x=236-180

7x=236-180

x=56/7

x=8

therefore a child will cost $8 and adult will cost $15

Answer:

18n-42 should make it as simple as it can be.

Answer:

[tex]40x+25y=19,000[/tex]

Step-by-step explanation:

[tex]x[/tex] denotes the number of adult admission tickets sold and [tex]y[/tex] denotes the number of child admission tickets sold.

Cost of an adult admission ticket = $40

Cost of [tex]x[/tex] adult admission tickets = $40[tex]x[/tex]

Cost of a child admission ticket = $25

Cost of [tex]y[/tex] child admission tickets = $25[tex]y[/tex]

Total amount paid by 625 people = $19,000

So,

[tex]40x+25y=19,000[/tex]

Answer:

-8

Step-by-step explanation:

-31 and +31 cancel each other out leaving you with -8

Answer:

i- um chile anywaysssss

41.25 because you divide the cost into the profit and that equals 41.25

Answer:

$41.25

Step-by-step explanation:

recall that the formula for percent markup is

% Markup = [ (price - cost) / cost ]     x     100%   (also see attached for reference)

we are given:

% Markup = 65%

Cost = $25

Simply substitute the known values into the formula above

% Markup = [ (price - cost) / cost ]       x     100%

65 = [ (price - 25) / 25]     x 100

65/100 = (price - 25) / 25

0.65 = (price - 25 ) / 25

0.65 (25) = price - 25

price - 25 = 16.25

price = 25 + 16.25

price = $41.25

Answer:

H<18

Step-by-step explanation:

Answer:

(c-k)÷3=x

Step-by-step explanation:

subtract the k first on both sides, cancelling the one on the left but adding a -k on the right.

than divide both sides by 3, cancelling the 3 and adding a ÷3 outside the parantheses

Answer:

D. -3 and 3

Step-by-step explanation:

We are given an output of 2. This means this is the value we need an input for. We need to find a number(s) that lie on the x axis and when we move up, you get an output of 2.

Option A:

If we are given an input of -2, we start at (-2, 0) and move up until we reach a point on the line. We end up lying on the point (-2, 3). Thus, the output for having an input of -2 is 3 which proves that this answer is incorrect.

Option B:

As stated above -2 has an output of 3 which is wrong. Since we know this, we can eliminate this as an option.

Option C:

If we are given an input of -3, we start at (-3, 0) and move up until we reach a point on the line. We end up lying on the point (-3, 2). Thus, the output for having an input of -2 is 2 which proves that this answer is correct.

Option D:

We know that -3 is a possible input so we just need to check 3 as an input.

If we are given an input of 3, we start at (3, 0) and move up until we reach a point on the line. We end up lying on the point (3, 2). Thus, the output for having an input of 3 is 2 which proves that this answer is also correct.

Since we know that -3 and 3 are possible inputs for an output of 2 on the graph, we need to include them both in our answer. Thus, the answer is D.

Best of Luck!

Huh? what do you mean

Step-by-step explanation:

perimeter of the quadrilateral is 39

area is 64

for ease for I got approximate numbers.

Distance = 13 units

Point A: (8, -7)

Point B: (-4, -2)

[tex]\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }[/tex]

[tex]\sqrt{(12)^{2} + (-5)^{2} }[/tex]

[tex]\sqrt{144 + 25 }[/tex]

[tex]\sqrt{169}[/tex]

[tex]13[/tex]

Answer:

[tex]\boxed {d = 13}[/tex]

Step-by-step explanation:

Use the Distance Formula to help you find the distance between the two following points:

[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]

(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)

-Apply the two following onto the formula:

[tex](x_{1}, y_{1}) = (8, -7)[/tex]

[tex](x_{2}, y_{2}) = (-4, -2)[/tex]

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

-Solve for the distance:

[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]

[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]

[tex]d = \sqrt{144 + 25}[/tex]

[tex]d = \sqrt{169}[/tex]

[tex]\boxed {d = 13}[/tex]

Therefore, the distance is [tex]13[/tex].
