The manager of a toy store bought 10 toy cars. The cars came in p packages. Write an expression that shows how many toy cars were in each package.
we can write x = 10/p to represent the number of toy cars x, in each package.
What is an Expression?Expression: An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.) Expressions can be thought of as similar to phrases. In language, a phrase on its own may include an action, but it doesn't make a complete sentence
The management purchased n cars, which equals 10.
There were p packages altogether, and each box contained one car. Per bundle, there should be x cars
Since there are x cars in each box, p packages would contain x*p cars
The equation can be written as 10 = x*p because we know there were p packages with 10 cars in them.
The multiplication of x and p is indicated by an asterisk (*).
You can write x = 10/p to represent the number of cars x, in each package.
The division symbol is denoted by a slash (/).
Because the number of cars and parcels can only be whole numbers, the values of x and p must also be whole numbers. Since the result of x and p is 10, both x and p must be factors of 10.
The factors of 10 are: 1,2,5 and 10
So, we get the following scenarios:
1 package with 10 cars inside it
2 packages each with 5 cars
5 packages each with 2 cars
10 packages each with 1 car
If the number of cars/packages must be greater than 1, then we have the following two cases:
2 packages each with 5 cars
5 packages each with 2 cars
we can write x = 10/p to represent the number of toy cars x, in each package.

-13 = 12 (False).
For ordered pair (0, -2), we have:
4y - 6x = 12
4(0) - 6(-2) = 12
0 + 12 = 12
12 = 12 (True).
For ordered pair (3, -4), we have:
4y - 6x = 12
4(3) - 6(-4) = 12
12 + 24 = 12
36 = 12 (False).
For ordered pair (0, 3), we have:
4y - 6x = 12
4(0) - 6(3) = 12
0 + 18 = 12
18 = 12 (False).
For ordered pair (6, 4), we have:
4y - 6x = 12
4(6) - 6(4) = 12
24 - 24 = 12

The Commutative Property of Addition states that for all expressions a and b, ab = ba
The answer to the given statement is FALSE. This is the commutative property of multiplication and not of addition.
What is the commutative property of addition?To "commute" is to move about or travel. According to the commutative property of addition, the sum is unaffected by changes in the order of the numbers being added.
The formula for the commutative property of numbers is A + B = B + A if two numbers A and B are supplied.
A + B = B + A
A × B = B × A
A - B ≠ B - A
A ÷ B ≠ B ÷ A
According to the commutative property formula, the result is unaffected by the sequence in which two numbers are added or multiplied. However, the order of the integers matters for subtracting and dividing any two real numbers, so it cannot be changed.

Nathan earns $6.50 an hour, plus tips, as a waiter in a restaurant. Suppose he works 26 hours in a week. How much money in tips must he receive to earn at least $229?
If Nathan earns $6.50 an hour, plus tips, as a waiter in a restaurant, and he worked for 26 hours, then he must receive $60 in tips, to earn a total of $229 in that time period.
As per the question statement, Nathan earns $6.50 an hour, plus tips, as a waiter in a restaurant, and he worked for 26 hours.
We are required to calculate the amount of tips Nathan must receive to earn a total of $229, working for 26 hours.
To solve this question, we will first calculate the amount Nathan can earn from his regular salary rate, working for 26 hours, and then subtract that amount from $229 which he earned as his salary from the restaurant plus his tips while working for those 26 hours.
Therefore, Nathan will earn $(26 * 6.50) = $169 in his regular salary from the restaurant working for 26 hours.
But since Nathan earned a total of $229 working at the restaurant for the same 26 hours, the extra money over his salary must be the amount he earned in tips.
Therefore, Nathan received $(229 - 169) = $60 in tips, to earn a total of $229 working for 26 hours at the restaurant.

Find the value of the missing angles, marked a, b and c. Give a reason for each stage of your working.
The unknown angles of the diagram is as follows;
a = 32°b = 20°c = 128°How to find angles?The missing angles of the diagram can be found as follows:
The sum of angles in a triangle is 180 degrees.
Therefore,
32 + 128 + b = 180
160 + b = 180
b = 180 - 160
b = 20°
Therefore,
a = 32°(alternate angles)
Alternate angles are congruent.
180 - a - b = c (sum of angles on a straight line)
180 - 32 - 20 = c
c = 180 - 32 - 20

QUESTION B
Both plans cost the same at the point where the two graphs intercept. Checking the graph, this occurs when:

B.) 1
C.) X
D.) f(x)
The value of h(f(x)) is x which is the C option in the question.
It is given in the question that h(x) is the inverse of f(x).
We have to find the value of h(f(x)).
If h(x) is the inverse of f(x), we can write is as:-
[tex]f^{-1}(x)=h(x)[/tex]
Hence,
h(f(x)) = [tex]f^{-1}(f(x))=(f^{-1}f)(x) = x[/tex]
Hence, the value of h(f(x)) is x.

a bald eagle sits in his nest in a tree at the top of the mountain. the nest is 1284 feet above the ground the eagle can dive at a rate of 88 feet/second what is the eagles height h after 7 seconds? the function rule for the height of the eagle after s seconds is? after 7 seconds the eagles height is?
The function rule for the height of the eagle after s seconds is h(s) = 1284 - 88s.
The height of eagle after 7 seconds is 668 feet.
Given that:-
Height of nest = 1284 feet
Speed of the bald eagle = 88 feet/second
Hence, we can write, after s seconds,
Height of eagle after s seconds = height of the nest - Time (in seconds) * Speed of the eagle
Hence,
h(s) = 1284 - s*88
h(s) = 1284 - 88s.
From the above equation, we can find the height of the eagle after 7 seconds.
h(7) = 1284 - 88*7 = 1284 - 616 = 668 feet.

You need to cover more than 8 miles in order to raise your part of the money. Which of the following linear inequalities can be used to determine how long you must walk (w) and run (r) in order to cover more than 8 miles? O 4w + 6r > 8 4w + 65 = 8 O 4w + 6r > 8 O 4w + 6r
We need to determine which of the given inequalities can be used to determine how long you must walk (w) and run (r) in order to cover more than 8 miles.
We know that you can walk at a rate of 4 mi/h, and run at a rate of 6mi/h.
Thus, if you walk for w hours, you will walk a distance d₁, in miles, given by:
[tex]d_1=4w[/tex]Also, if you run r hours, you will run a distance d₂, in miles, given by:
[tex]d_2=6r[/tex]Now, notice that the total distance is the sum of d₁ and d₂. And the total distance, in miles, must be greater than 8.
We represent 'greater than' using the symbol '>':

2>8−43h
The solution to the inequality expression given as 2 > 8 - 43h is h > 6/43
How to determine the solution to the inequality?The inequality expression is given as
2 > 8 - 43h
Subtract 8 from both sides of the inequality expression
So, we have the following expression
2 - 8 > 8 - 8 - 43h
Evaluate the difference in the above expression
So, we have the following expression
-6 > - 43h
Divide both sides of the inequality by -43
So, we have
-6/-43 > - 43h/-43
Evaluate the quotient
6/43 < h
Rewrite as
h > 6/43
Hence, the value of the inequality is h > 6/43
