The value of the variables in the equation are as follows:
1. x = -4 / 9
2. t = -8
3. x = -54
4. x = -3
5. x = 1 / 6
How to solve an equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.
Let's find the solution of the equations. The solution of the equation is the value of the variable x. A variable is a number represented by a letter in an equation.
Therefore,
1.
-4 = 9x
divide both sides of the equation by 9
x = - 4 / 9
2.
−32=4t
divide both sides of the equation by 4
t = - 32 / 4
t = - 8
3.
x − 18 = −72
add 18 to both sides of the equation
x - 18 + 18 = -72 + 18
x = -54
4.
−18 = x − 15
add 15 to both sides of the equation
-18 + 15 = x - 15 + 15
-3 = x
x = -3
5.
−24x = −4
divide both sides of the equation by - 24
x = - 4 / -24
x = 1 / 6

sara has 20 sweets
12 liquorice sweets , 5 mint sweets and 3 humbugs.
sara takes two random sweets
work out probability that the two sweets will not be the same
If sara takes two random sweets. The probability that the two sweets will not be the same is :111/190.
How to find the probability?Probability of getting two of each sweet:
P( Liquorice) = (12/20)×(11/19)
P (Liquorice) =132/380
P (mints) =(5/20)×(4/19)
P (mints) =20/380
P (Humbugs) =(3/20)×(2/19)
P (Humbugs) =6/380
Probability that two sweets will be the same
P(same) =132/380+20/380+6/380
P(same) =158/380
Hence,
Probability that two sweets will not be the same
P(not same) = 1- (158/380)
P(not same) =380 -158 /380
P(not same) = 222 /380
P(not same) =111 /190
Therefore the probability is 111/190.

In the translation T of the graph below, use the figure to describe the following transformation.
The translation T due to the transformation is (5,3)
How to describe the transformation using the figure?Translation can be defined as movement in a straight line
Given the rule: (x,y) → (x + 3, y + 1) as seen in the image. That means (x,y) translated to (x + 3, y + 1). This is what we use to solve this problem.
From the figure, the value of (x, y) can be read i.e. (x, y) = (2,2)
Thus the translation will be:
(x,y) → (x + 3, y + 1)
(2,2) → (2 + 3, 2 + 1) = (5, 3)
Therefore, the translation T of the transformation shown in the graph is (5, 3)

square tile measures 12 inches on each side. If 1 inch = 2.54 centimeters, determine the area of the tile in square centimeters. Round the answer to the nearest square centimeter. 30 cm2 144 cm2 366 cm2 929 cm2
The area of the tile in square centimeters is 929cm2
The area in square centimeters is calculated as follows
First, let convert the tile measures 12 inches on each side into centimeters
1 inch = 2.54 centimeters

a rancher has 200 feet of fencing with which to enclose two adjacent rectangular corrals (see figure). what dimensions should be used so that the enclosed area will be a maximum?
The dimension of each corral should be 25 feet in width and 33⅓ feet in length so that the enclosed area will be a maximum.
Adjacent rectengular corral has length and width with area formula as below.
A = L × W
Given:
The dimension of adjacent rectangular corrals are the same.Adjacent side = 200 feet.Because the dimension of adjacent rectangular corrals are the same, so:
W = 4x
L = 3y
3y + 4x = 200
[tex]y = \frac{200 - 4x}{3} [/tex]
There are two adjacent rectangular corrals, so:
A = 2×L×W
[tex]A = 2 \times \frac{200 - 4x}{3} \times \: x [/tex]
A = ⅓(400x–8x²)
We can differentiate to get the maximum area:
⅓×(400x–8x²) = 0
400–16x = 0
16x = 400
x = 25 feet
Substitute x value (width) to get y value (length):
y = (200–4(25)) ÷ 3
y = (200–100) ÷ 3
y = 100 ÷ 3
y = 33⅓ feet

Use three unit multipliers to convert 5280ft to meters
The three-unit multipliers are follows, 5280ft × 12 inches × 2.54 cm × 0.01 meter and it will be 1609.344 meters.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.
As per the given,5280ft
It is known that 1 ft = 12 inches.
5280ft = 5280 x 12 inches
It is known that 1 inch = 2.54 cm
5280 x 12 inches = 5280 x 12 x 2.54 cm
It is known that 1 cm = 0.01 meter
5280 x 12 x 2.54 cm = 5280 x 12 x 2.54 x 0.01 meter
⇒ 1609.344 meters

The width, labelled x in the figure is 162.5 meters
How to determine the width of the rectangle?From the question, we have the following parameters that can be used in our computation:
Length = 650 - 2x
Width = x
The area of a rectangle is the product of its dimensions
So, we have
Area = Length x Width
Substitute the known values in the above equation, so, we have the following representation
A = (650 - 2x) * x
Evaluate
A = 650x - 2x²
Differentiate and set to 0
650 - 4x = 0
So, we have
4x = 650
Divide by 4
x = 162.5

The expressions for the length, width, and height are 18 - 2x, 12 - 2x, and x while the volume function is V = (12 - 2x)(18 - 2x)x
(a) How to determine the expression for the length, width, and heightFrom the question, we have the following parameters:
Dimension of sheet = 8 inches by 12 inches
Also from the question, we understand that:
He cuts equal squares from each corner.
The cut-out length from the sheet would represent the height of the box
Represent this cut-out length with x
So, we have
Height = x
The width and the length are then represented as
Width = Initial width - 2x
Length = Initial length - 2x
So, we have
Width = 12 - 2x
Length = 18 - 2x
(b) Write a function for the volumeThe volume of a box is the product of its dimensions
In this case, we have
Width = 12 - 2x
Length = 18 - 2x
Height = x
So, we have
Volume = Width * Length * Height
Substitute the known values in the above equation So, we have the following equation
V = (12 - 2x)(18 - 2x)x
So, the volume function is V = (12 - 2x)(18 - 2x)x
