Lea's school is selling tickets to the annual talent show. On the first day of ticket sales the school sold 12 adult tickets and 7 child tickets for a total of $236. The school took in $217 on the second day by selling 7 adult tickets and 14 child tickets. What is the price each of one adult ticket and one child ticket?
Answer:
Step-by-step explanation:
let the number of children be x
and the number of adults be y
so
7x+12y=236-----1
and
14x+7y=217------2
equating both 1 and 2 we have
7x+12y=236-----1
14x+7y=217------2
multiply 1 by 2
subtract 2 from 1 we have
14x+24y=472-----3
- 14x+7y=217------2
0x+17y=255
17y=255
y=255/17
y=15
put y=15 in eqn 1 we have
7x+12y=236-----1
7x+12*15=236-----1
7x+180=236-----1
7x=236-180
7x=236-180
x=56/7
x=8
therefore a child will cost $8 and adult will cost $15
Esmeralda and Genevieve are both planting square gardens. Esmeralda's garden is 25 square feet and
Genevieve's is 4 square yards. Convert their garden sizes to the same units (feet) to determine who's garden has a
larger area. (1 point)
Genevieve's garden is 12 square feet and thus, has a smaller area than Esmeralda's
Genevieve's garden is 16 square feet and thus has a smaller area than Esmeralda's
O Genevieve's garden is 25 square feet, and thus has the exact same area as Esmeralda's
Genevieve's garden is 36 square feet, and thus, has a larger area than Esmeralda's
Answer:
Genevieve's garden is 12 square feet and thus, has a smaller area than Esmeralda's
Step-by-step explanation:
Given:
Esmeralda's garden = 25 square feet
Genevieve's garden = 4 square yards
Convert Genevieve's units (yards) to feet
Yards to feet
1 yard = 3 feet
4 yards = 4 * 3 feet
4 yards = 12 feet
Genevieve's garden = 12 square feet
Genevieve's garden is 12 square feet and thus, has a smaller area than Esmeralda's
Answer:
The answer is: Genevieve's garden is 36 square feet, and thus, has a larger area than Esmeralda's

1. The sum of 5 and x is 20. What is x?
If the sum of 5 and x is 20, then the value of x will be 15.
It is given that the sum of 5 and x is 20.
Mathematically, it can be written as:
5 + x = 20
We have to find the value of x.
In order to find the value of x we need to separate the variable and constant.
For this, subtract 5 from both the sides:
5+x-5 = 20-5
5-5 +x = 20-5
Then, solve the operation of subtraction on both the sides of above equation.
0+x = 15 -------(A)
Since, when we add 0 to any quantity, the result will be this quantity itself.
So, 0+x = x -------(B)
From (A) and (B), Sine the left sides of equation (A) and (B) are equal, then the right sides will also be equal.
Equation right sides of (A) and (B). We have:
x = 15
Hence, the value of x is 15.

Are the triangles PQR and RST similar why or why not?
Answer: The triangles are similar
======================================================
Explanation:
The square markers show that
angle RPQ = angle RST = 90 degrees
So that's one pair of congruent angles. Another pair of congruent angles is what you see in the diagram below. The angles marked in red are congruent alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.
Since we have two pairs of congruent angles, we can use the AA (angle angle) similarity theorem to prove the triangles congruent.
Answer:
Triangle PQR and RST are both right triangles but they do not share the same side lengths. They also share the same point R, so I would say that they are similar only because they are both right triangles.

As angle 6y° and angle( 13y - 10 )° are interior angles on the same side of transversal their sum will be equal to 180° .
Then :-
[tex]6y + 13y - 10 = 180[/tex]
[tex] 19y - 10 = 180[/tex]
[tex]19y = 180 + 10[/tex]
[tex]19y = 190[/tex]
[tex]y = \frac{190}{19} [/tex]
[tex]y = 10[/tex]
Which means :-
= 13y - 10
= 13 × 10 - 10
= 130 - 10
= 120°
Then angle 6y :-
= 6 × 10
= 60°
As angle 60° and angle 9x + 12° are a linear their sum will also add up to form 180° .
Which can be written as :-
[tex]60 + 9x + 12 = 180[/tex]
[tex]9x + 72 = 180[/tex]
[tex]9x = 180 - 72[/tex]
[tex]9x = 108[/tex]
[tex]x = \frac{108}{9} [/tex]
[tex]x = 12[/tex]
Then :-
= Angle 9x + 12
= 9 × 12 + 12
= 108 + 12
= 120°
Therefore , the value of y = 10 and the value of x = 12 .
Which equation has exactly one solution in common with the equation y=6x-2?
A. 18x - 3y = 6
B. 1/2y = 3x - 2
C. 2y = 4x - 12
D. 18x - 12 = 3y
Answer:
A. 18x - 3y = 6
Step-by-step explanation:
By taking 3 common from the terms 18x and 3y we get,
3 (6x-3y) = 6
or, 6x - y = 6/3
or, 6x - y = 2
And,
The equation becomes,
y = 6x - 2
The equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.
What is a system of equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
An equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
By taking 3 commons from the terms 18x and 3y we get,
3 (6x-3y) = 6
6x - y = 6/3
6x - y = 2
The equation becomes,
y = 6x - 2
Therefore, the equation has exactly one solution in common with the equation y=6x-2 will be 18x - 3y = 6. The correct option is A.
