adult ticket = 10
child ticket = 4
Step-by-step explanation:
for example…
adult ticket = xchild ticket = yso that we get a system of equations
9x + 5y = 110…Equation 1
x + y = 14…Equation 2
solve the system of equations, this time I will use the Elimination and Substitution method
9x + 5y = 110
x + y = 14 (multiplied by 5)
↓↓↓↓↓↓↓
9x + 5y = 110
5x + 5y = 70
___________ _
4x = 40
x = 10
to find value of y subtitute x to one of Equation. for example from second Equation…
x + y = 14
10 + y = 14
y = 14 - 10
y = 4
∴ So, the number of each ticket was she bought is 10 adult ticket and 4 child ticket.

What is the solution to?
7x – 2y = 18
—4x + 3y = –14
• (-2, 2)
• (1, 6)
• (4, 5)
• (2, - 2)
Answer:
(2, -2)
Step-by-step explanation:
Solve 7x - 2y = 18 for x:
[tex]7x - 2y = 18[/tex] [tex]7x - 2y + 2y = 18 + 2y[/tex] (Add 2y to both sides)[tex]7x = 2y + 18[/tex] [tex]\frac{7x}{7} = \frac{2y+18}{7}[/tex] (Divide both sides by 7)[tex]x = \frac{2}{7}y+\frac{18}{7}[/tex]Substitute 2/7y+ 18/7 for x in -4x + 3y = -14
[tex]-4x + 3y = -14[/tex] [tex]-4(\frac{2}{7}y+\frac{18}{7})+3y=-14[/tex] [tex]\frac{13}{7}y-\frac{72}{7}=-14[/tex] (Simplify both sides of the equation) [tex]\frac{13}{7}y-\frac{72}{7}+\frac{72}{7} =-14+ \frac{72}{7}[/tex] (Add 72/7 to both sides)[tex]\frac{13}{7}y=\frac{-26}{7}[/tex] [tex]\frac{13}{7}y*\frac{7}{13}=\frac{-26}{7} * \frac{7}{13}[/tex] [tex]y = -2[/tex]Substitute -2 for y in x = 2/7y + 18/7
[tex]x = \frac{2}{7}y + \frac{18}{7}[/tex] [tex]x = \frac{2}{7}(-2) + \frac{18}{7}[/tex] [tex]x = 2[/tex] (Simplify both sides of the equation)Given that x = 2 and y = -2, the point is: (2, -2)
Therefore, the solution is (2, -2).

10 computer operators can compose 120 pages in 2 hours. How many operators should work, if the same job is to be completed in 30 minutes?
Answer:
40 Operators
Step-by-step explanation:
if 10 operators worked on 120 pages for 2 hours
P operators will work on the same pages for 30min
note: 2hrs= 120min
10×120min/120= P × 30/120
cross multiply make P subject of the formulaP= 10×120×120/120×30
P = 40 operators

Step-by-step explanation:
We have been given an equation t=\frac{1}{500}dt=

d , where d represents distance traveled in miles and t represents time in hours.
To find the time taken by the flight to travel 800 miles, we will substitute d=800d=800 in our given equation as:
t=\frac{1}{500}\times 800t=

×800
t=\frac{800}{500}t=

t=1.6t=1.6
1 hour equals 60 minutes.
0.6 hours = 0.6*60 minutes = 36 minutes.
Therefore, it will take the plane 1.6 hours or 1 hour 36 minutes to travel 800 miles.

Krutika can type 2400 words in 40 minutes.
Who types at the fastest rate of words per minute?
А
Caroline
B
Krutika
С
Natasha
Answer:
caroline types 3500/50=70 words in 1 minute
natasha.............4550/70=65..................................
krutika................2400/40=60...............................
so the answer is A
Step-by-step explanation:
Answer:
A) Caroline
Step-by-step explanation:
To find this, simply divide the amount of words they type by the amount of minutes they type:
To solve Caroline's do:
3500/50=70
Caroline types 70 words per minute.
To solve Natasha's do:
4550/70=65
Natasha types 65 words per minute.
To solve Krutika's do:
2400/40=60
Krutika types 60 words per minute.
Since Caroline has the highest wpm, we can safely say that Caroline types the fastest rate of words per minute.

what is the range i need help
Answer:
[-7, 0]
Step-by-step explanation:
The range describes all values that y can take on. You may notica that the highest point of the graph has an y coordinate of 0 while the lowest has one of -7. Both values are included because they have filled in dots: this means the parenthesis are closed. So, the range would be: [-7, 0]. An alternate way to write this is [tex]-7\leq y \leq 0[/tex].
A bag contains
18
red balls and
4
blue.
What percentage of balls are red?
Answer:
81% of the balls are red
Step-by-step explanation:
If you want to find the percentage of balls that are red you will have to divide it by the total number of balls in the ball
18 red + 4 blue = 22 balls part (a)
18/22 = 9/11 part (b) simplify
9/11 * 100 part (c) multiply the fraction by a hundred to get the percentage
81.81 ~ 81% part (d) solve
Answer:
81 9/11%
Step-by-step explanation:
First add the number of red and blue balls together. 18 + 4 = 22
What is the number of red balls? It’s 18
We have to begin by writing this information as a fraction. 18 balls would be the numerator and the total of red and blue balls together, 22 will be the denominato. Now, we have the fraction, 18 (red) / 22 (total). To find the percentage, divide the numerator by the denominator. 18 divided by 22, which is 9/11. Now multiply 9/11 by 100, which gives you 81 9/11%.
Therefore, the answer is 81 9/11%.

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
The given expression is
csc² (x) - 2csc(x) cot(x) + cot² (x) = tan² (x/2)
Proceed LHS
csc² (x) - 2csc(x) cot(x) + cot² (x)
⇒ (1/sin²(x) ) - 2(1/sin(x) )(cos(x)/sin(x)) + (cos(x)/sin(x))²
⇒ (1 - 2cos(x) + cos(x)²)/sin(x)²
⇒ (1 - 2cos(x) + cos(x)²)/sin(x)²
⇒ (1 - cos(x))²/sin(x)²
⇒ (1 - cos(x))²/sin(x)²+
⇒ [(1 - cos(x))/sin(x)]² [ since tan(x/2) =(1 - cos(x))/sin(x)]
⇒ [ tan(x/2) ]²
⇒ tan²(x/2) = RHS
