How is multiplying a whole number by a mixed number the same as multiplying two mixed numbers?
because you make them all improper fractions
Multiplying a whole number by a mixed number involves the same principle as multiplying two mixed numbers in maths. Both first require converting the numbers into improper fractions, then multiplying the numerators together, and the denominators together, and finally simplifying the result.
Explanation:In mathematics, multiplying a whole number by a mixed number is fundamentally the same as multiplying two mixed numbers because both processes follow the same principle. Let's break it down step by step: First, both whole numbers and mixed numbers can be converted into improper fractions. For example, if you are multiplying 3 (a whole number) by 2 1/2 (a mixed number), you would first convert them into improper fractions. So, 3 becomes 3/1, and 2 1/2 becomes 5/2.
Then, you would multiply the numerators (top numbers) together and the denominators (bottom numbers) together, i.e., (3 * 5)/(1 * 2) = 15/2. Then, you simplify the fraction if needed.
The same process applies when multiplying two mixed numbers, for example, 2 1/2 * 1 1/4. Convert them to improper fractions (5/2 * 5/4), then multiply the numerators and denominators and simplify the result. Thereby, the principles of multiplication and conversion of numbers apply identically in both scenarios.

|2*z - 9| = 1
How do I find z in this equation?
Let's solve your equation step-by-step.
|2z − 9| = 1
Solve Absolute Value.
|2z − 9| = 1
We know either 2z − 9 = 1 or 2z − 9 = −1
2z − 9 = 1 (1 is a possibility)
2z − 9 + 9 = 1 + 9 (Add 9 to both sides)
2z = 10
2z /2 = 10 /2 (Divide both sides by 2)
z=5
2z − 9 = −1 (Possibility 2)
2z − 9 + 9 = −1 + 9 (Add 9 to both sides)
2z = 8
2z /2 = 8 /2 (Divide both sides by 2)
z = 4

|n-3|=5 solve for n and graph the solution set
[tex]|n-3|=5\iff n-3=5\ \vee\ n-3=-5\qquad|\text{add 3 to both sides}\\\\n=8\ \vee\ n=-2[/tex]
The solution for the equation |n-3|=5 is n=8, -2. These two points, when graphed on a number line represent the solution set.
Explanation:In Mathematics, the absolute value of a number can have two possible solutions because it represents the distance from zero, and distance is always positive. To solve the equation |n-3|=5, we need to break it down into two separate equations.
When the term inside the absolute value (n-3 in this case) is positive, the equation is simply n-3=5. Solving for n gives n=8.
When the term inside the absolute value is negative, the equation is -(n-3) = 5, or equivalently, 3-n=5. Solving for n in this case gives n=-2.
So the solution set for n is {8, -2}. To graph the solution set on a number line, draw a number line from -3 to 9 and put closed dots at n=-2 and n=8.

(b) 4x + 5 - 6x = -x +3 -x +2
(c) 8x + 2 - 6 = 4x +8 +3x
Answer:
Step-by-step explanation:
Problem A
3x - 5 + x = 2x - 3 + 2 + 2x
Bring like terms close to each other so they can be combined on both the left and right sides.
3x + x - 5 = 2x+ 2x - 3 + 2 Combine like terms
4x - 5 = 4x - 1 Stop. Nothing more is going to work and give you anything but No Solution. You will wind up with - 5 = - 1 which is a contradiction.
Number of Solutions: None
Classification: Contradiction
Problem B
4x + 5 - 6x = -x + 3 - x + 2 Bring like terms close to each other so they can be combined on both the left and right sides.
4x - 6x + 5 = -x - x + 3 + 2
-2x + 5 = - 2x + 5 Stop!!!
This will give an infinite number of solutions. Suppose x = 200. Then you will get
-2*200 + 5 = -2 * 200 + 5
- 400 + 5 = - 400 + 5

Problem C
8x + 2 - 6 = 4x +8 +3x Bring like terms close to each other so they can be combined on both the left and right sides.
8x + 2 - 6 = 4x + 3x + 8 Combine like terms.
8x - 4 = 7x + 8 Subtract 7x from both sides
8x - 7x - 4 = 7x - 7x + 8 Combine like terms
x - 4 = 8 Add 4 to both sides
x = 4 + 8

A planter in the shape of a cube has a volume of 1000in3 is the area of the base of the cube greater than or less than 1 square foot?explain
The cube volume is 10x10x10 inch3, so the base area is 10 inch x10 inch. On the other hand, we know that 1 square foot = 1 foot x 1 foot = 12 inch x 12 inch, so that is *greater* than the cube base.
Answer:
area of the base of the cube is smaller than 1 square foot
Step-by-step explanation:
since the volume of the cube is 1000 in^3 then its side must be (1000)^{1/3}
which is equal to 10 in
now, we know that area of the base of the cube will have an square cross section area= side^2
there area of base of the cube = 10^2= 100 sq in
now 1 foot= 12 in
therefore, 1 square foot = 12*12 square in = 144 sq in
clearly, area of the base of the cube is smaller than 1 square foot.

can someone explain the law of syllogism and the law of detachment for geometry???
Law of detachment is used when you have a conditional statement and another statement that matches the hypothesis of the conditional. ... Law of syllogism is used when you have two conditionals and the hypothesis of one matches the conclusion of the other.
Final answer:
In geometry, the law of syllogism allows for the combination of two conditional statements to reach a conclusion, while the law of detachment allows us to derive a conclusion from a known hypothesis and a conditional statement.
Explanation:
The Law of Syllogism and Detachment in Geometry
Both the law of syllogism and the law of detachment are forms of deductive reasoning used in geometry. The law of detachment is a process where we derive a conclusion from a single conditional statement and its hypothesis. For example, if we have a statement 'If a figure is a square, then it has four equal sides', and we know that a given figure is a square, we can deduce that this figure has four equal sides.
The law of syllogism, on the other hand, allows us to combine two conditional statements to derive a new conclusion. If we have two true statements, such as 'If an angle is acute, then it is less than 90 degrees' and 'If an angle is less than 90 degrees, then it is not a right angle', we can then conclude that 'If an angle is acute, then it is not a right angle'.
These laws form the backbone of logical reasoning in mathematics, allowing us to connect premises to reach valid conclusions and build upon established theorems and properties in geometry.
