3. A full-price ticket for a college basketball game costs $2.50, and a student ticket costs $1.75. If
Dennis_Churaev [7]

Let's say x = full price tickets

Let's say y = student tickets

We can write two equations:

From "585 tickets were sold" we can make the equation:

x + y = 585

And from "Full-price ticket is $2.50 and student ticket is $1.75 and total receipts is $1,217.25"...we can make the equation:

2.50x + 1.75y = 1,217.25

So now we can use substitution to find our answer...since we only have to find how many student tickets...we will solve the first equation for x so we can plug that into the 2nd equation to solve for y.

x + y = 585

x + y - y = 585 - y

x = 585 - y

Now we plug that into our 2nd equation: 2.50 (585 - y) + 1.75y = 1217.25

Distribute your 2.50

1462.5 - 2.50y + 1.75y = 1217.25

Add the y's: 1462.5 - 0.75y = 1217.25

Subtract 1462.5 from both sides:

1462.5 - 0.75y - 1462.5= 1217.25 - 1462.5

-0.75y = -245.25

Divide both sides by -0.75:

y = -245.25/-0.75

y = 327

        There were 327 student tickets :)

At a sale on winter clothing, Cody bought four pairs of gloves and four hats for $36.00. Tori bought three pairs of gloves and f
iren [92.7K]

Answer:

gloves cost $5

hats cost $4

Step-by-step explanation:

four pairs of gloves and four hats for $36.00

4g + 4h = 36

three pairs of gloves and four hats for $31.00

3g + 4h = 31

-------------------------

Subtract the second equation from the first

  4g + 4h = 36

-( 3g + 4h = 31 )

––––––––––––

   g           = 5

gloves cost $5

substitute for g = 5 into either equation

4(5) + 4h = 36

20 + 4h = 36

Subtract 20 from both sides

4h = 16

Divide both sides by 4

h = 4

hats cost $4

Find the distance between A (4, 6) and B (9, 7). Write your answer as a radical and as a decimal rounded to the nearest
Stells [14]

The distance between A (4, 6) and B (9, 7) is √26 or 5.1.

<h3>How to find the distance between two points?</h3>

Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;

d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }

Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;

d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }

So the distance between A (4, 6) and B (9, 7) will be

d = \sqrt {\left( {4 - 9 } \right)^2 + \left( {6 - 7 } \right)^2 }

d = √26 = 5.099

Rounded to nearest tenth ⇒ 5.1 units.

Hence "The distance between A (4, 6) and B (9, 7) is √26 or 5.1".

Please help with this!!!
iris [78.8K]

Answer: The y values remain the same, but the x value changes its sign

Step-by-step explanation: There is a way to remember this. If you reflect across the y axis the y will stay the same and, if you reflect across the x axis the x will stay the same. So if the axis is in the problem then that axis will stay the same and the other axis will change to its opposite.
