Answer:
Step-by-step explanation:
First you determine the variables x and y as:
x: the value for student tickets
y: the value for chaperone tickets.
Knowing that student tickets cost $ 2 more than companion tickets, it is represented by the equation:
x= y +2
On the other hand, there were 59 students and 6 companions. And the total cost of admission for the group was $ 508, that is to say that what all the students and the companions have paid adds up to $ 508. Expressed by an equation:
59x + 6y = 508
Then the system of equations to solve and thus obtain the price of a student ticket and the price of a companion ticket is:
[tex]\left \{ {{x=y+2} \atop {59x+6y=508}} \right.[/tex]
Solving for x, the price of a student ticket:
Rearranging the first equation,
y = x - 2
Replacing in the second equation and solving for x:
59*x + 6*(x -2)=508
59*x + 6*x -12=508
65*x -12=508
65*x= 508 +12
65*x= 520
[tex]x=\frac{520}{65}[/tex]
x=8
The cost of a student ticket is 8$

find value of x and y
Given :
There is a quadrilateral.Two sides of the quadrilateral are parallel .Four angles are 96° , 2x° , 94° & ( 3y + 44 )°.To Find :-
The value of x & y .Solution :-
Here , 96° & 2x° are co - interior angles and we know that the sum of co - Interior angles is 180°.
⇒ 96° + 2x = 180° .
⇒ 2x = 180° - 96° .
⇒ 2x = 84° .
⇒ x = [tex]\red{\sf \dfrac{84^{\circ}}{2}}[/tex]
[tex]\bf\longmapsto x = 42^{\circ}[/tex]
Hence value of x is 42° .
Similarly , 94° & ( 3y + 44) ° are co- interior angles
⇒ 94° + ( 3y + 44)° = 180° .
⇒ ( 3y + 44 )° = 180° - 94° .
⇒ 3y + 44° = 86°.
⇒ 3y = 86° - 44° .
⇒ 3y = 42° .
⇒ y = [tex]\sf \red{\dfrac{42^{\circ}}{3}}[/tex]
[tex]\bf\longmapsto y = 14^{\circ}[/tex]
Hence the value of y is 14°.

Answer:
∠BEC = 54°
Step-by-step explanation:
ED and EA are opposite rays, which means that they form a straight angle.
Straight angle = 180°
Which means that,
∠AEB + ∠BEC +∠DEC = ∠AED
This is the equation we are going to use,
We also know that ∠CED = 72°
We know that BE bisects ∠AEC
Know, we know that ∠AEB = (7x - 2)°
That means ∠BEC = (7x - 2)° - This is because ∠AEB = ∠BEC
=>(7x - 2)° + (7x - 2)° + 72° = 180°
=> (14x - 4)° + 72° = 180°
=> (14x - 4)° = 180° - 72°
=> (14x - 4)° = 108°
=> 14x = 108° + 4°
=> 14x = 112°
=> x = (112 / 14)°
=> x = 8°
So, know we can find ∠BEC
(7x - 2)°
=> (7 * 8 - 2)°
=> (56 - 2)°
=> 54°

What are the values of x and y?
image attached. Thank you!
Answer:
C
Step-by-step explanation:
We'll have to use trigonometry for this.
First, note that in right triangle ABC, if we look from the perspective of angle A, the opposite side is x, the adjacent side is y, and the hypotenuse is 18.
In order to find x, then, we must use sine, which is opposite/hypotenuse. So:
sin(A) = sin(60) = opposite/hypotenuse = x/18
sin(60) is equal to (√3)/2, so multiplying both sides by 18 gives:
[(√3)/2] * 18 = 9√3
Already, we can tell that the answer is likely C, but let's find y to make sure.
We will use cosine to find y because cos = adjacent/hypotenuse.
cos(A) = cos(60) = adjacent/hypotenuse = y/18
cos(60) = 0.5, so multiplying both sides by 18 gives:
0.5 * 18 = 9
So, y = 9.
Thus, C is our answer.
~ an aesthetics lover
Answer:
C
Step-by-step explanation:
Using the cosine/ sine ratio in the right triangle and the exact values
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] and sin30° = [tex]\frac{1}{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{x}{18}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2x = 18[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
x = 9[tex]\sqrt{3}[/tex]
----------------------------------------------------------
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{y}{18}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2y = 18 ( divide both sides by 2 )
y = 9
Thus
x = 9[tex]\sqrt{3}[/tex] and y = 9 → C

650 divided by 3/2 (With the full explanation)
Answer:
Multiply the numerator by the reciprocal of the denominator to get 650 x 2 divided by 3. Then, multiple 650 and 2 which is 1300, then it is 1300 over 3, or 433.3, and it is repeating.
Step-by-step explanation:
By the concept of division by a fraction, 650 divided by 3/2 will result in [tex]433 \frac{1}{3}[/tex].
We have to solve 650 divided by 3/2.
Mathematically, it can be expressed as:
650 ÷ [tex]\frac{3}{2}[/tex] -----(1)
To solve the above expression, at first we can apply the concept of dividing by a fraction. Which say that:
dividing by a fraction = multiplying by the reciprocal of the fraction
And the reciprocal of any fraction is simply the ratio of denominator and numerator.
So, the reciprocal of [tex]\frac{3}{2}[/tex] is [tex]\frac{2}{3}[/tex] .
Then, expression (1) will be equivalent to
[tex]650 \div \frac{3}{2} = 650 \times \frac{2}{3}[/tex] ------(2)
That means we have to multiply 650 and fraction 2/3.
To get the multiplication of two fractions, we multiply the numerators together and the denominators together.
[tex]650 \times \frac{2}{3} = \frac{650\times 2}{3}[/tex]
[tex]650 \times \frac{2}{3} = \frac{1300}{3}[/tex]
[tex]650 \times \frac{2}{3} = \frac{1300}{3}[/tex]
[tex]650 \times \frac{2}{3} = 433 \frac{1}{3}[/tex]
Thus, from equation (2)
[tex]650 \div \frac{3}{2} = 433 \frac{1}{3}[/tex]
Hence, 650 divided by 3/2 is:
[tex]650 \div \frac{3}{2} = 433 \frac{1}{3}[/tex]
