Solve each equation. 3 x⁻¹=24
The solution of the given expression 3x⁻¹=24 is x = 1/8.
What is meant by exponents?An exponent (also known as a power or degree) indicates the number of times the base is multiplied by itself. For example,'has an exponent of 5 and a base of. This means that variable would be multiplied 5 times by itself. This can also be thought of as to a fifth power.
Some properties of the exponents are given as-
Zero Property: Any non-zero real number raised to a power of zero equals one.Negative Property: Whatever nonzero real number raised to either a negative power is one divided by the same number raised to a positive power.Product Property: When two exponents that have the same nonzero real number base are multiplied, the result is the sum of the exponents that have the same base.Quotient Property: When two exponents that have the same nonzero real number base are divided, the result is the difference of the exponents that have the same base.Now, for the stated question;
The given expression is;
=> 3x⁻¹ = 24
Divide both sides by 3.
=> x⁻¹ = 8
Taking the reciprocal on both sides.
=> 1/x⁻¹ = 1/8

Answer: The value of the triangle = 3.
The value of the square = -2,
The value of the star = 7
The value of the rhombus = 18.
The value of the circle = 4,
The value of the right angle triangle = -5
Step-by-step explanation:
Define Linear equation:
A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.
An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation always forms a straight line.
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Given that,
Let us assume the values is,
(Option 1) : A shape puzzle is given that,
Let's assume, the triangle shape represents = a
Let's assume, the square shape represents = b
Let's assume, the star shape represents = c
The equation becomes,
clue 1 : 2a-1 = 5
clue 2 : a + b = 1
clue 3 : a-2b = c
First take, clue 1 : 2a-1 = 5
2a = 5+1
2a = 6
a = 6/2
a = 3
Therefore, triangle (a) = 3
Take, clue 2 : a + b = 1
Replace 'a' value in this equation,
a + b = 1
3+b = 1
b = 1-3
b = -2
Therefore, square (b) = -2
Take clue 3 : a-2b = c
Replace with 'a' and 'b' values in this equation,
a-2b = c
3-2(-2) = c
3+4 = c
c = 7
Therefore, star (c) = 7
we can substitute these values,
Then, clue 1 : 2(3) -1 = 6-1 = 5
clue 2 : 3 + (-2) = 3-2 = 1
clue 3 : 3-2(-2) = 3+4 = 7
Thus, The value of the triangle = 3.
The value of the square is = -2,
The value of the star = 7
after using the concept of linear equation in two variables.
(Option 2) : A shape puzzle is given that,
Let's assume, the rhombus shape represents = x
Let's assume, the circle shape represents = y
Let's assume, the right angle triangle shape represents = z
The equation becomes,
clue 1 : x+2 = 5y
clue 2 : 3y = 12
clue 3 : 2y = x+2z
Take, clue 2 : 3y = 12
y = 12/3 = 4
Therefore, circle (y) = 4
First take, clue 1 : x+2 = 5y
x+2=5(4)
x+2=20
x = 20-2 = 18
Therefore, rhombus (x) = 18
Take clue 3 : 2y = x+2z
Replace with 'x' and 'y' values in this equation,
2y = x+2z
2(4) = (18)+2z
2(4) = (18)+2z
8 = (18)+2z
8-18 = 2z
-10 = 2z
z = -10/2
z = -5
Therefore, right angle triangle (z) = -5
we can substitute these values,
Then, clue 1 : 18+2=5(4)
20 = 20
clue 2 : 3(4) = 12
12 = 12
clue 3 : 2(4) = 18+2(-5)
8 = 18-10
10+8 = 18
18 = 18
Thus, The value of the rhombus = 18.
The value of the circle = 4,
The value of the right angle triangle = -5
after using the concept of linear equation in two variables.

If a union wage negotiator feels that the probabilities are 0.40,0.30,0.20 and 0.10 that the union members will get a $1.50 an hour raise, a $1.00 an hour raise,a $0.50 an hour raise, or no raise at all , find their expected raise.
The expected raise a union wage negotiator feels that the union members will get is $1.22.
The probability of each pay raise is given below
P ($1.50 raise) = 0.40
P ($1.00 raise) = 0.30
P ($0.50 raise) = 0.20
P (no raise) = 0.10
The probability of each pay raise is then multiplied by the pay itself
Expected raise for each hour = $1.50(0.40) + $1.00(0.30) + $0.50(0.20) + $0.00(0.10)
E(x) = 0.6 + 0.52 + 0.1 + 0 (The probability of no pay at all gives 0 since the pay amount has no value)
E(x) = $1.22
Therefore, all together the union wage negotiator is able to predict a $1.22 pay raise for the workers for each time expected.

A.It is less than one of the forces.
B.It equals one of the forces.
C.It is zero.
D.It is greater than both forces.
C.It is zero.
Step-by-step explanation:The net force is the sum of all of the forces exerted on an object.
Identifying Forces
Force is measured in newtons, which is shortened to N. Additionally, force will always have a direction, like 5N up or 3N to the left.
Sometimes force will be negative to represent direction. A force moving down or to the left might be negative because moving down or to the left on an axis moves towards negative numbers.
Net Force
As stated above, the net force is the sum of all of the forces acting on an object. For example, if one object is being moved 5N to the left and 4N to the right, the net force will be 1N to the left.
On the other hand, if the forces are balanced, like 5N on both the left and right, then the forces cancel out. This leaves a net force of 0.

Answer:
30 c + 100 m = 700
c+ m = 14
Step-by-step explanation:
The product of the number of movies where the song was played (m) multiplied by the earnings per movie (30) plus the product of the number of commercials where the song was played (m) multiplied by the earnings per commercial, must be equal to $700.
30 c + 100 m = 700
The number of movies (m) plus the number of commercials (c) is equal to 14.
c+ m = 14
The system is:
30 c + 100 m = 700
c+ m = 14
A long-distance athlete can run 12 kilometer in 3 minutes. How many kilometers can he run in an hour?
1/2 km 3/60 hr=1/2×60/3 its a yes or no question
If a long run athlete can run 1/2 km in 3 minutes then he can run 10 km in an hour.
Given, a long distance athlete can run 1/2 kilometer in 3 minutes.
How much distance can he cover in an hour = ?
How quickly something or someone is moving is determined by their speed. If you know how far an object has traveled and how long it has taken, you can calculate its average speed. Speed equals distance times time, according to the speed formula. Knowing the units for distance and time will help you determine what the units are for speed.
Time = 60 minutes.
we know that 3 minutes = 1/2 km
therefore, distance covered in an hour = 1/2 ÷ 3/60
= 1/2 × 60/3
= 1/2 × 20
= 10
distance covered in an hour = 10 km.
hence we get the distance covered by the athlete in an hour as 10 km.

Application problem with a linear function: Finding a coordinate given the slope and a point
The height of the candle which is a linear function with respect to time after 12 hours was 25.2 centimeters.
What is a linear function?A linear function has a graph of a straight line.
Given that height of a candle is a linear function of the amount of time in hours it has been burning.
The slope(m) is = - 0.4 which is = -(4/10) = - (2/5).
The height of the candle after 19 hours is 22.4 centimeters, which can be written as two points (x,y) = (19,22.4).
Now to obtain the height of the candle first we have to form an equation of a line in slope intercept form to find y-intercept(b), which is,
y = mx + b.
22.4 = -(2/5).19 + b.
22.4 = -7.6 + b.
b = 22.4 + 7.6.
b = 30.
∴ y = -(2/5)x + 30.
Now to obtain the height of the candle after 12 hours we have to substitute 12 in x.
