Answer:

adult tickets: $13student tickets $7

Step-by-step explanation:

The given equations are ...

  4a +5s = 87

  2a +2s = 40

We observe that the coefficient of 'a' in the first equation is 2 times that in the second equation. We can multiply the second equation by -2 and add it to the first to eliminate 'a' terms.

  (4a +5s) -2(2a +2s) = (87) -2(40)

  4a +5s -4a -4s = 87 -80 . . . . . . . . . eliminate parentheses

  s = 7 . . . . . . . . . . . . . . . . . .simplify

  2a +2(7) = 40 . . . substitute for s in the second equation

  2a = 26 . . . . . . subtract 14

  a = 13 . . . . . . . divide by 2

Adult tickets cost $13; student tickets cost $7.

Answers

Answer:

Step1. Slope is zeroStep2. Angles 5, 8, 9 and 12

Step-by-step explanation:

Step 1

Parallel lines have the same slope.

Gray Dr is parallel to Brodie Ln

They both are parallel to x-axis, therefore both have a zero slope.

Step 2

m∠6 = x°

Angles 5 and 8 are supplementary with angle 6, so they have a measure of (180 - x)°.

Also, since Gray Dr is parallel to Brodie Ln and Canon Rd is transversal, the angles 9 and 12 have the same measure. Because ∠6 and ∠10 are corresponding angles.

Both A and B

Step-by-step explanation:

Both a and b. A three-way intersection can be referred to as a T-intersection or a Y-intersection, depending on the shape of the intersection. In a T-intersection, one road intersects another road perpendicularly, forming a T-shape. In a Y-intersection, one road splits into two branches, forming a Y-shape.

What is a constant of proportionality?

The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.

When y and x are two quantities that are directly proportional to one another, the proportionality constant k is defined as k=y/x.

Given that Nicole had a collection of 60 stuffed animals. She gave away 5 stuffed animals per month until all her stuffed animals were gone.

The equation can be written as:-

y = kx

The value of k will be calculated as :-

what is the value of x^2 - 6x + 9 when x = 2 + i?

Answers

The Expression x^2 - 6x + 9 when x = 2 + i   is -2i

To evaluate the expression x^2 - 6x + 9 when x = 2 + i, we substitute the value of x into the expression:

(2 + i)^2 - 6(2 + i) + 9

Simplifying the first term, we get:

(2 + i)^2 = 2^2 + 2(2)(i) + i^2 = 4 + 4i + i^2

Since i^2 = -1, we can substitute that in and simplify further:

(2 + i)^2 = 4 + 4i - 1 = 3 + 4i

Now we substitute this into the original expression:

(2 + i)^2 - 6(2 + i) + 9 = (3 + 4i) - 6(2 + i) + 9

Simplifying further, we get:

= 3 + 4i - 12 - 6i + 9

= 0 - 2i

= -2i

Therefore, the value of x^2 - 6x + 9 when x = 2 + i is -2i.

We have to given that;

Functions are,

f (x) = (- x + 5) / (3x + 3)

And, g (x) = (x + 5) / (- 2x - 6)

Now, We can formulate;

⇒ f (x) × g (x)

⇒ (- x + 5) / (3x + 3) × (x + 5) / (- 2x - 6)

⇒ (5 - x) × (5 + x) / (3x + 3) (- 2x - 6)

⇒ (25 - x²) / (3x + 3) (- 2x - 6)

⇒ (x² - 25) / (3x + 3) (2x + 6)

⇒ (x² - 25) / 6 (x + 1) (x + 3)

Hence, Domain are all real numbers expect x = - 1, and x = - 3

1) a meal for 6 cost £12 per person. as it is one of the diners birthday , the other 5 decided to pay for his meal. how much do each of the five friends need to pay?

Answers

Each of the five friends needs to pay £14.40 to cover the cost of the birthday person's meal.

To calculate how much each of the five friends needs to pay, we can use the concept of averages or mean.

The total cost of the meal for 6 people is £12 per person. This means that the total cost of the meal is 6 * £12 = £72.

Since the other five friends have decided to pay for the birthday person's meal, they will evenly divide the total cost of £72 among themselves.

To find the average amount each friend needs to pay, we divide the total cost by the number of friends paying, which is 5:

£72 / 5 = £14.40

Using the concept of averaging or finding the mean allows us to distribute the cost equally among the friends, ensuring fairness in sharing the expenses.

What is the sum of numbers?

A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, thousand, or a million. There are summations with an infinite number of terms.

As given, one number is 7 times the first number, third number is 100 more than the first number and the sum of three numbers is 649.

Suppose the first number is x, then the second number is 7x and the third number is x + 100.

Sum of these three numbers is, 649.

x + 7x + x + 100 = 649

                    9x = 549

                      x = 61

Therefore, the first number is 61, the second number is 7x = 427, and the third number is x + 100 = 161.

What is the exact value of sin pi/3?

Answers

The exact value of sin(pi/3) is √3. By definition, the sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse. Therefore, sin(pi/3) = √3/1 = √3.

The exact value of sin(pi/3) can be determined using trigonometric properties and identities.

First, we know that pi/3 is equivalent to 60 degrees. In a unit circle, the point corresponding to 60 degrees forms an equilateral triangle with the origin and the x-axis. This triangle has side lengths of 1, 1, and √3.

To find the sine of pi/3, we consider the side opposite the angle (pi/3) in the triangle. In this case, the opposite side has a length of √3. The hypotenuse of the triangle is 1, as it is the radius of the unit circle.
