Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

what is the area of this trapezoid?
help me plz i will give brainliest
Answer:
a. t = I/Pr
b. The value of t in the table is 3 years
Step-by-step explanation:
Solve for t in the formula.
I = Pr
~Divide pr to both sides
I/Pr = t
Using the formula above, we can solve for t.
75/(500)(0.05) = t
75/25 = t
3 = t

Answer:
1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2

Im so glad I could help! I hope you pick my answer as the Brainliest!
Answer:
Step-by-step explanation:
Since this is a test, I'll give a hint.
This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.
If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?
You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.
Hope this helps!
Plz help ASAP! Show how you did it if possible.

Explain how to solve the equation and how to check the solution.
40 = 8y
there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.
equations by using inverse operations, including squares, square roots, cubes, ... A pair of inverse operations is defined as two operations that will be ... The following examples summarize how to undo these operations using their ... x is divided by 2, so we multiply by 2 on both sides. 2. 8 2. 2 x. ∙ = ∙. Solution: 16. explanation:

Which statements are true?
Select each correct answer.
Function 1 has a greater rate of change than function 2.
Function 2 has a greater rate of change than function 1.
Function 1 has a greater y-intercept than function 2.
Function 2 has a greater y-intercept than function 1.
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.
Step-by-step explanation:
Given that function 1 has the table;
x y
0 -2
2 0
3 1
5 3
Finding the slope of the linear function gives the rate of change of the function. In this case,
m=Δy/Δx
m=3-1/5-3 = 2/2 =1
The equation of the linear function is given as;
m=Δy/Δx
y-3/x-5= 1
y-3=x-5
y=x-5+3
y=x-2
y-intercept is -2
In function 2, the line passes through points (-2,0) and (0,4)
Finding the slope of the line,
m₁=Δy/Δx
m₁=4-0/0--2
m₁= 4/2 =2
Rate of change is 2
Finding the equation of the line
y-4/x-0 = 2
y-4=2(x-0)
y-4 =2x
y=2x+4
The y-intercept is 4
The statements that are true are;
Function 2 has a greater rate of change than function 1.
Function 2 has a greater y-intercept than function 1.

Step-by-step explanation:
The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.
Answer: The drawing in the attached figure
Step-by-step explanation: we know that
An isosceles triangle, has two equal sides and two equal interior angles
In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle
step 1
Find the measure of the vertex angle
Remember that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
Let
x ---> the measure of the vertex angle of triangle
step 2
Find the length of the congruent sides of triangle
Applying the law of sines
Let
c ----> the length of one congruent side
we have
substitute
solve for b
step 2
Make a scale drawing of the entryway
The scale drawing is 1 cm : 2 cm
That means
1 cm in the drawing represent 2 cm in the actual
or
1 cm in the drawing represent 0.02 m in the actual
Find the dimensions in the drawing
For a=8 m
For b=5.22 m
step 3
Draw the triangle
