Answer:
280 adult tickets
130 student tickets
190 children tickets
were sold at the concert
Step-by-step explanation:
Let the number of students be s , adults a and children c
Total 600;
Thus;
a + s + c = 600 •••••••(i)
let us look at revenue
Revenue = number * ticket price
For adults; a * 7 = $7a
For students ; s * $3 = $3s
For children; c * $2 = $2c
Total is 3150
thus;
7a + 3s + 2c = 3150 ••••••••(ii)
150 more adults than students;
a = s + 150 ••••••(iii)
Substitute iii into ii and i
into ii
7(s + 150) + 3s + 2c = 3150
7s + 1050 + 3s + 2c = 3150
9c + 3s = 3150-1050
9c + 3s = 2,100 •••••••(x)
Substitute into i
a + s + c = 600
s + 150 + s + c = 600
2s + c = 600 - 150
2s + c = 450
c = 450 - 2s ••••••(xx)
Now substitute xx into x
9(450-2s) + 3s = 2100
= 4050-18s + 3s = 2100
4050-2100 = 18s - 3s
15s = 1950
s = 1950/15
s = 130
c = 450 -2s
c = 450 - 2(130)
c = 450 - 260
c = 190
a = 150 + s
a = 150 + 130
a = 280

Describe the transformation of the parent function f (x) = | x |
as it relates to the function g(x)=-2 | x+6 | -3
Answer:
A reflection over the x-axis, a vertical stretch by 2, a horizontal shift left 6, and a vertical shift down 3
Step-by-step explanation:
y=a|x-h|+k is the form for these types of equations.
a values describe the vertical stretch (skinnier) or shrink (wider)
h values represent the horizontal (left/right) change. The h value in the equation is negative, so make sure to take that into consideration.
k values represent the vertical (up/down) change

Answer:
(7x-15) = 180
7x = 195 (add 15 to both sides)
195 / 7 = 27.85
(x + 28) + (4x -3) + 27.85 = 180
5x + 53.85 = 180 (add like terms)
5x = 126.15 (subtract 53.85 from both sides)
x = 25.23 (dived both sides by 5)

I could be wrong though

Joan performed an experiment on two different types of cells and noted their sizes as follows:
Cells Size
Cell A 0.0005×10−5 m
Cell B 0.0025×10−7 m
What is the ratio of the size of cell A to the size of cell B?
Answer: Press this link to get your answer -)
Step-by-step explanation:
The ratio is simply the fractional representation of two values in their simplest form. The ratio of Cell A to Cell B is 20 which means that the size of Cell A is 20 times the size of Cell B.
Given that :
Cell size A = [tex]Cell A = 0.0005\times 10^{-5}\\\\Cell B = 0.0025\times10^{-7} \\\\Ratio = \frac{Cell A }{Cell B} \\\\Ratio = \frac{0.0005 \times 10^-5}{0.0025 \times 10^-7}[/tex]
[tex]Ratio = 20[/tex]
Therefore, the ratio of the size of Cell A to the size of Cell B is 20 : 1, which can be interpreted to mean that cell A is 20 times larger than cell B.

The perimeter is 24
Step-by-step explanation:
BD = AD and we know that AD is 3 so we know the little side is exactly 6 long.
Because they are right triangles, both of the long sides are equal.
AC is 9 so BC must also be 9.
We break this into 9 + 9 + 6 which equals 24

Answer:
y= 1/14 x +17/14

Lines perpendicular to another line have an opposite reciprocal slope, meaning that the sign is changed, and the fraction is flipped. We are going to use point-slope form to solve.

Hiroaki says that a constant of proportionality must be a whole number and cannot be a fraction or a decimal. Explain why Hiroaki is incorrect.
Hiroaki is mistaken since the line should pass through the origin, negating the possibility of the proportionality constant being a simple whole number.
What are Whole Numbers?Whole numbers are defined as natural numbers plus zero (0). We are aware that the term "natural numbers" refers to a group of counting numbers beginning with 1, 2, 3, 4, and so forth. Whole numbers are a collection of numbers that don't contain any fractions, decimals, or even negative integers. It is made up of zero and positive integers. Alternately, we may define whole numbers as the collection of non-negative integers. The inclusion of zero in the set of whole numbers marks the main distinction between them and natural numbers.
What is a fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
What is a decimal ?A decimal is a number that is divided into two parts: a whole and a fraction. Between integers, decimal numbers are used to express the numerical value of complete and partially whole quantities.
