What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
Here,
Total number of tickets brought=30
Total amount paid=$200
Cost of kid ticket=$3.5
Cost of adult ticket=$8
Cost of senior ticket=$6
Let x, y, z be the number of tickets brought for kid, adult, senior.
x+y+z=30
3.5x+8y+6z=200
2y=x+z
x+y+z=30
3y=30
y=10
x+z=20
z=20-x
3.5x+80+6(20-x)=200
3.5x+80+120-6x=200
2.5x=0
x=0
z=20
He bought 0 tickets for kid, 10 tickets for adult and 20 tickets for senior with an amount of $200.

In a fish tank, 4/9 of the fish have a red stripe on them. If 12 of the fish have red stripes, how many total fish are in the tank?
Answer: If 4/9 of the fish have a red stripe, we can determine the total number of fish in the tank by dividing the number of fish with red stripes by the fraction of fish with red stripes. This gives us 12 / (4/9) = 12 * (9/4) = 27 fish. So, there are 27 fish in the tank.
[tex] \frac{4}{9} x = 12[/tex]
[tex]x = 12 \times \frac{9}{4} [/tex]
[tex]12 \times 9 = 108[/tex]
[tex]4 \times 1 = 4[/tex]
[tex]x = \frac{108}{4} [/tex]
[tex]x = 27[/tex]
There are 27 fish in the tank. Hope this helps.
What is the slope of the line that passes through (-5,6) and (-2,4)
The slope of the line that passes through the given points (-5, 6) and (-2, 4) as required in the task content is; -2 / 3.
What is the slope of the line that passes through the given points; (-5,6) and (-2,4)?It follows from the task content that the slope of the line that passes through the given points; (-5,6) and (-2,4) be determined as required.
On this note, since the slope, otherwise termed the average rate of change is given by the formula;
Slope, m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Therefore, given the points; (-5, 6) and (-2, 4), the required slope of the line is;
m = ( 4 - 6 ) / ( -2 - (-5) )
m = -2 / (-2 + 5)
m = -2 / 3
Therefore, the required slope of the line which passes through the given points is; -2 / 3.

What is midpoint theorem?The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half of the length of the third side.
From the given figure, n is the midpoint of one side of the quadrilateral and m is the midpoint of other side of the quadrilateral.
Pair of opposite sides are parallel
Since, m and n are midpoints on two sides of quadrilateral, so the line passes through the midpoints is parallel to other two sides
Then, ∠n =73° and ∠m =51°
p = 1/2 ×48
⇒ p =24 cm
Therefore, the length of line p is 24 cm.

What is depreciation?Depreciation is an accounting technique for spreading out the expense of a tangible item over the course of its useful life. Depreciation is a measure of how much an asset has been utilized for. It enables businesses to purchase assets over a predetermined length of time and generate income from those assets.
Given that,
Marisa buys a car for $20,000 = P
depreciates at a rate of 12% per year = r
and t is the for the time period.
As we know,
[tex]A = P (1-r)^t[/tex]
Where, A is the value of object after x period of time.
The value of Terrence's car after x years is:

Barbara wants to restore her '66 Mustang in 4 years. She puts $200 into an account every month that pays 1.05% interest, compounded monthly. How much interest did she gain in 4 years?
Using the formula of compound interest, the amount accumulated over 4 years is $15,849.46
Compound InterestCompound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period. In Mathematics, compound interest is usually denoted by C.I.
The formula is often given as;
C.I = P(1 + r/n)^nt
C.I = Compound InterestP = principal r = raten = number of times compoundedt = timeSubstituting the values into the formula
C.I = 200(1 + 0.0105/12)^12*4
However, over the period of 4 years, the Principal becomes
Principal = 200 * 4 * 12 = 9600
Rate = 1.05 * 12 = 12.6
C.I = 9600(1 + 12.6/12)^12 * 4
C.I = $15,849.46

Let's understand what is the Subtraction property
By balancing an equation with the same mathematical operation on both sides, the term "subtraction property of equality" is used.
Given inequality m< A + M <B = M<C. if we subtract both side equal value then we will get M<A = M<C - M<B. then we will get this result

Transitive-According to the transitive property, "all the quantities are equal to each other if two quantities are equal to the third quantity."
Symmetric-Actually quite straightforward, equality has the symmetric property. According to this property, if a = b, then b must also be a. In other words, even if two equations' sides are switched, the.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
