The school that Chelsea goes to is selling tickets to a choral performance. On the first day of
ticket sales the school sold 8 adult tickets and 7 child tickets for a total of $133. The school took
in $132 on the second day by selling 9 adult tickets and 2 child tickets. Find the price of an adult
ticket and the price of a child ticket.
Answer:
Adult: $14 each
Child: $3 each
Step-by-step explanation:
Day 1: (14*8)+(3*7) = 112+21 = 133
Day 2: (14*9)+(3*2) = 126+6 = 132

Can anyone explain the method for algebraic fraction? We have to do it for maths, and i'm really struggling with it. Here is an example question for what i'm doing.
[tex]\frac{x+1}{2}[/tex] + [tex]\frac{x+2}{5}[/tex] = 3 I need to find x
If you could do a detailed explanation on how to reach the answer that would be perfect.
Answer:
x=3
Step-by-step explanation:
The approach is not very different from regular fractions.
You have to get to a common denominator to be able to add them.
10 is a good denominator (multiply the denominators).
multiply the first term by 5, and the second one by 2:
[tex]\frac{5 \cdot (x+1)}{5 \cdot 2} + \frac{2 \cdot (x+2)}{2 \cdot 5} = 3[/tex]
[tex]\frac{5x+5 + 2x+4}{10} = 3[/tex]
[tex]\frac{7x+9}{10} = 3[/tex]
7x + 9 = 30
7x = 30 - 9
x = 3
let me know if you need more details on one of the steps

A business has two different offices, one in London, the other in New York.
The ratio of the number of staff at the London office to New York office is 3:5
Employees of the business are either part time or full time.
In London 30% of the staff are part time
In New York 20% of the staff are part time
Given that the business has 38 part-time members of staff, work out the total number
of employees.
Answer:
3:6
Step-by-step explanation:
If business has 38 part-time members of staff then the total number of employees exists 160.
What is meant by expression?Mathematical expressions consist of at least two numbers or variables, at least one math operation, and a sentence. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: (Number/variable, Math Operator, Number/variable) is an expression.
A number, a variable, or a combination of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.
Based on the given conditions, formulate:
[tex]$x \times(30 \% \times 3+20 \% \times 5) \div(3+5)=38$[/tex]
Calculate the sum or difference:
[tex]$\frac{x \times(0.3 \times 3+0.2 \times 5)}{8}=38$[/tex]
Divide both sides of the equation by the coefficient of variable: [tex]$x=38 \times \frac{8}{0.3 \times 3+0.2 \times 5}$[/tex]
Calculate the product or quotient:
[tex]$x=38 \times \frac{8}{0.9+0.2 \times 5}$[/tex]
To simplify the value of x, we get
[tex]$x=38 \times \frac{8}{0.9+1}$[/tex]
[tex]$x=38 \times \frac{8}{1.9}$[/tex]
[tex]$x=38 \times \frac{8}{\frac{19}{10}}$[/tex]
Divide a fraction by multiplying its reciprocal:
[tex]$x=38 \times 8 \times \frac{10}{19}$[/tex]
Write as a single fraction:
[tex]$x=\frac{38 \times 8 \times 10}{19}$[/tex]
Calculate the product or quotient:
[tex]$x=\frac{304 \times 10}{19}$[/tex]
simplifying the above equation, we get
x = 3040/19
x = 160
The value of x exists 160.
Therefore, the total number of employees exists 160.

Solve the simultaneous equations below. Show your work clearly,
a)
y-2x = 6
A
y + 2x = 6
Answer:
The solution of the given two equations
( x, y) = (0,6)
Step-by-step explanation:
Step(i)
Given equations are
y - 2x = 6 ...(i)
y + 2x = 6 ...(ii)
Adding (i) and (ii) equations, we get
y - 2x + y +2x = 6+6
2 y = 12
y =6
Step(ii):-
substitute y =6 in equation (i). we get
y - 2x =6
6 - 2x =6
6-6 =2x
0 = 2 x
x = 0
The solution of the given two equations
( x, y) = (0,6)

Answer:
The correct option is;
An isosceles trapezoid with legs of length 8
Step-by-step explanation:
The correct option is an isosceles trapezoid with legs of length 8
The given properties of the quadrilateral are;
1) One pair of equal opposite sides
2) One pair of parallel opposite sides
From the given options, the two options which are not parallelograms are the kite and the trapezoid
However given that the option of the kite has a pair of adjacent side of length 8, with the given pair of equal length opposite side of length 8, we have that all the sides of the quadrilateral will be of length 8, and the figure cannot be a kite
An isosceles trapezoid of leg length 8 has one pair of equal length opposite sides of length 8 and one pair of parallel sides of unequal length
Given that the length of the lines that make up the pair of opposite parallel sides in the figure are not specified, the figure can be described by as being an isosceles trapezoid.

Use the diagram of ◾ABC to find m<D
M<D=
Answer:
In quadrilateral ABCD we have
AC = AD
and AB being the bisector of ∠A.
Now, in ΔABC and ΔABD,
AC = AD
[Given]
AB = AB
[Common]
∠CAB = ∠DAB [∴ AB bisects ∠CAD]
∴ Using SAS criteria, we have
ΔABC ≌ ΔABD.
∴ Corresponding parts of congruent triangles (c.p.c.t) are equal.
∴ BC = BD.
