The solution of inequality expression [tex]\frac{h}{-24} \leq 18[/tex] is [tex]{h} \leq -432[/tex], i.e. option C, i.e. h less-than-or-equal-to negative 432.
How to solve inequality expression?Use addition, subtraction, multiplication and division to move the variable to one side and isolate it. Once you have isolated the variable, you have solved the inequality. Reverse the inequality sign whenever you multiply or divide by a negative number.
We have,
An inequality expression [tex]\frac{h}{-24} \leq 18[/tex]
Now,
Multiplying on both sides by (-24),
i.e.
[tex]\frac{h}{-24}*(-24) \leq 18*(-24)[/tex]
On solving inequality expression
We get,
[tex]{h} \leq -432[/tex]
So,
Option C is the correct answer, i.e. Solution of inequality expression is
h less-than-or-equal-to negative 432.
Hence, we can say that the solution of inequality expression [tex]\frac{h}{-24} \leq 18[/tex] is [tex]{h} \leq -432[/tex], i.e. option C, i.e. h less-than-or-equal-to negative 432.

What is the solution to -(4x-3) = -7(9+x) ???
Answer:
The solution is -22
Step-by-step explanation:
The solution of an equation is the value of the variable of the equation
∵ -(4x - 3) = -7(9 + x)
→ Simplify each side
∵ -(4x) - -(3) = -7(9) + -7(x)
∴ (-4x) - (-3) = -63 + (-7x)
→ Remember (-)(-) = (+) and (-)(+) = (-)
∴ -4x + 3 = -63 - 7x
→ Add 7x to both sides
∴ -4x + 7x + 3 = -63 - 7x + 7x
∴ 3x + 3 = -63
→ Subtract 3 from both sides
∵ 3x + 3 - 3 = -63 - 3
∴ 3x = -66
→ Divide both sides by 3
∴ x = -22
∴ The solution is -22

Answer:
You can use the formula for the perimeter of a square to find the length of one of the square's sides. Then substitute that information into the formula for the area of a square and solve.
Step-by-step explanation:
Taking the exam same as you 90 % sure this is right
The area of the square can be gotten by using the perimeter of the square to get the length of the square. Then, we use the length to find the area of the square.
Properties of a square.All the sides are equalAll the angles are equal.All the sides are parallel to each other.Therefore,
perimeter of a square = 4l
where
l = length of squareTherefore,
4l = 20
divide both sides by 4
l = 20 / 4
l = 5 meters
Therefore,
area of the square = l²
where
l = side lengtharea of the square = 5²
area of the square = 25 cm²

Part B. Write an equation to model the solution to the problem.
Enter the correct answers in the boxes.
A. $ =
B. Equation =
Answer:
The friends split the bill at 15.32$
Step-by-step explanation:
So to find how much each paid you would take the bill total and divide it by the amount of people in this case three
And for the equation it would be 45.96/3=15.32$
The equation to model the solution to the problem would be; 3x = 45.96. the friends split the bill at 15.32 dollars.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables. A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be one degree.
Given that the dinner for Lorenzo and his 3 friends costs $45.96.
To determine how much each paid would take the bill total
Therefore, we will divide it by the number of people in this case three
3x = 45.96
x = 45.96/3
x = 15.32$

Amaya is asked to find the side lengths of the triangle
shown below. What is her error?
Answer:
Her error was that she equated 2x to 6 instead of equating 2x to 3x-5
Step-by-step explanation:
Find the diagram of the question attached.
According to the triangle given, you can see that the base angles are equal. This shows that the triangle is an isosceles triangle. If the base angles are the same, this means that the length of the slant sides are also equal i.e
2x = 3x-5
Get x first;
2x = 3x-5
2x - 3x = -5
-x = -5
x = 5
Get the side length
For side length 2x, the length is 2(5) = 10
For side length 3x-5, the length is 3(5) - 5 = 10.
Hence the length of the sides is 10
Amaya is wrong because she equated the wrong sides. She equated 2x to 6 instead of equating 2x to 3x-5 as shown in the calculation above.

In the equation, f(x)=2x-4(x+1), what is the value of f(-14)?
A. 32
B. -32
C. 5
D. 24
Answer:
D. 24
Step-by-step explanation:
Plug in -14 to the equation:
f(x) = 2x - 4(x + 1)
f(-14) = 2(-14) - 4(-14 + 1)
Simplify:
f(-14) = -28 - 4(-13)
f(-14) = -28 + 52
f(-14) = 24

A satellite radio company charges a one time fee of $36 for installation. The company also charges $42 per month for use. based upon this information complete this table showing the total cost of using the satellite radio after each month listed.
Answer:
Table shown below
Step-by-step explanation:
Linear Modeling
It consists of finding and using the equation of a line to represent the behavior of a real situation in numerical terms.
We are given the model of the charges for a satellite radio company that charges a fixed fee of $36 for installation and a variable fee of $42 per month for use.
The model is written as:
C(m) = 36 + 42m
Where m is the number of months.
For m=1:
C(1) = 36 + 42(1)=$78
For m=2:
C(2) = 36 + 42(2)=$120
For m=3:
C(3) = 36 + 42(3)=$162
For m=4:
C(4) = 36 + 42(4)=$204
For m=5:
C(5) = 36 + 42(5)=$246
