You were elected the student council president for the next year at your school. After vacation is over, you have to plan a school carnival for the new school year. You are studying last year’s event and know that 210 people attended last year’s school carnival. The total amount of money collected for tickets was $710. Prices were $5 for regular admission, $3 for students, and $1 for children. The number of regular tickets sold was 10 more than twice the number of children’s tickets sold. Determine how many of each kind of ticket were sold.
The number of regular tickets are 70, the number of student tickets are 110 and the number of children tickets are 30.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Given that, you are studying last year’s event and know that 210 people attended last year’s school carnival.
The number of regular tickets sold was 10 more than twice the number of children’s tickets sold.
Let the number of children tickets be x.
Then, number of regular tickets be 2x+10
Let the number of student tickets be y.
You are studying last year’s event and know that 210 people attended last year’s school carnival.
x+2x+10+y=210
3x+y=200 --------(I)
The total amount of money collected for tickets was $710.
Now, 5(2x+10)+3y+x=710
10x+50+3y+x=710
11x+3y=660 --------(II)
Substitute y=200-3x in equation (II), we get
11x+3(200-3x)=660
11x+600-9x=660
2x=60
x=30
Substitute x=30 in equation (I), we get
3(30)+y=200
y=110
Number of regular tickets =2x+10
= 70
Therefore, the number of regular tickets are 70, the number of student tickets are 110 and the number of children tickets are 30.

Answer:
x=24
<6=79°
Step-by-step explanation:
We can see that if we add 3x+7 and 4x+5, it will total a 180-degree angle. This allows us to solve for x. 3x+7+4x+5=180 7x+12=180 7x=180-12 7x=168 x=24 We can also see that angle six is the same as the angle 3x+7. Since we know x=24, we can solve for those angles. 3(24)+7= 72+7=79 So <6=79 degrees
5 people are in a line to withdraw money from the local Bank. All 5 withdrawal the same amount. The total withdrawn was $845. How much money did each withdraw? Set up an equation to find out how much money each person withdrew and then solve it.

Each person withdrew 169$ from their accounts.

Answer:
m<B = 141 degrees
Step-by-step explanation:
This shape is a heptagon meaning its angles should have a sum of 900 degrees.
we are given the degrees and we need to ad them up
148+90+120+129+130+142=749
then we subtract 749 from 900 which looks like
900-749=141
from subtracting 749 from 900 we get 141 hence we get our answer that m<B = 141 degrees
A computer and printer cost a total of $1101. The cost of the computer is two times the cost of the printer. Find the cost of each item.
Cost of computer:
Cost of printer:
Answer:
Cost of Computer: $734
Cost of Printer: $367
Step-by-step explanation:
These two equations can represent the costs; x = price of computer; y = price of printer.
x + y = 1101
2y = x
If you graph these, you get an intersection point of (734, 367). This means that the only place that both equations are fulfilled is on (734, 367).
Then you can check your work:
734+367=1101
367*2=734
what is the area of the triangle
Answer:
Use this to answer your question :)
Step-by-step explanation:
The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h.
Answer:
54 units²
Step-by-step explanation:
Formula we use,
→ Area = ½ × b × h
Now the area of the triangle is,
→ ½ × b × h
→ ½ × 18 × 6
→ 9 × 6
→ 54 units²
Hence, the area is 54 units².

A triangle has an area of 54 m² and a height of 9 m.
How long is the base of the triangle?
Enter your answer in the box.
Answer:
base = 3
Step-by-step explanation:
The area of triangle is calculated using the following formula:
1/2*b*h (b: base, h: height)
The area and height is given, to find the base we can make the following equation:
1/2*b*9 = 54
9b/2 = 54 multiply both sides by 2
9b = 27 divide both sides by 9
b = 3

RADIUS
==================================
PROBLEM
Mary’s bicycle wheel has a circumference of 226.08 cm². What is its radius?
SOLUTION
We can solve this problem using the circumference formula in which π stands for ( 3.14 ), C stands for circumference itself and r stands for radius.
\bold{Formula \: || \: C = 2πr}Formula∣∣C=2πr
\tt{226.08 = 2(3.14) r}226.08=2(3.14)r
'Now to find the radius,Substitute 226.08 for c which is circumference in the formula.
\begin{gathered} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{C = 2πr} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{226.08 = 2(3.14)\red{r}} \\ \\ \: \: \: \: \: \: \: \: \large \tt{ \frac{226.08}{6.28} = \cancel\frac{6.28 \red{r}}{6.28} } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{\tt\green{C = 36}}\end{gathered}
C=2πr
226.08=2(3.14)r
6.28
226.08
=
6.28
6.28r
C=36
To check:
\begin{gathered} \small\begin{array}{|c|}\hline \bold{circumference }\\ \\ \tt{C = 2πr} \\ \tt{C = 2(3.14) (36\:cm) } \\ \tt{C = 2(113.04\:cm) } \\ \underline{\tt \green{C = 226.08\:cm }} \\ \hline \end{array} \end{gathered}
circumference
C=2πr
C=2(3.14)(36cm)
C=2(113.04cm)
C=226.08cm
FINAL ANSWER
If Mary's Bicycle has a circumference of 226.08 cm then the radius is 36.
\boxed{ \tt \red{r = 36}}

Your first six-month auto insurance premium was $629.00. Based on your driving record, your renewal premium is $786.25. What percent increase did you see in your premium?
8%
20%
оооо
25%
32%
Hello!
Answer:
[tex]\Large \boxed{\sf 20\%}[/tex]
Step-by-step explanation:
→ We want to calculate the percentage increase we saw in our premium.
→ To calculate the percentage increase we saw in our premium, let's calculate the difference between our first six-month car insurance premium and our renewal premium:
[tex]\sf 786.25 - 629.00 = 157.25[/tex]
→ Calculate the percentage:
→ The formula used to calculate the percentage is:
[tex]\sf \dfrac{value}{total ~value} \times 100\%[/tex]
→ Apply this formula with value = 157.25 and total value = 786.25:
[tex]\sf \dfrac{157.25}{786.25} \times100\%[/tex]
→ Simplify the expression:
[tex]\sf \dfrac{157.25}{786.25} \times100\%\\\\\\= 0.2 \times100\%\\\\\\= 0.2 \times \dfrac{100}{100} \\\\\\= 0.2 \times 1\\\\\\= 0.2\\\\\\= \dfrac{20}{100} \\\\\\\boxed{\sf= 20\%}[/tex]
So the percentage increase we saw in our premium is 20%.
