Select the property of equality used to arrive at the conclusion. If x = 3, then x 2 = 3x the multiplication property of equality

the division property of equality

the addition property of equality

the subtraction property of equality

Answers

Answer 1

Answer:

Answer:

A.The multiplication property of equality

Step-by-step explanation:

We are given that

If x=3 then $x^2=3x$

We have to find that which property of equality used to arrive at the conclusion.

Let p: x=3

q: $x^2=3x$

There is q is conclusion is $x^2=3x$

If we multiply by x on both sides then we get

$x\cdot x=3\cdot x$

$x^2=3x$

Hence, the multiplication property of equality used to arrive at the conclusion.

Answer:A.The multiplication property of equality

Answer 2

Answer: I think it would be the Multiplication property of equality

If x ≠ 0, then x²/2x⁵ × 1000 is equivalent to

Answers

Answer:

Not telling you the answer that just the steps, that would be cheating.

Step-by-step explanation:

1. Mulitply 1000 by the fraction.

2. Simplify it(the numbers 1000 and 2 to 500 and 1)

3. Then divide the exponents(you know this I taught you:)

4. You then will get your answer! (hint: it has a negative exponent :)

5. Please try not to use Brainly next time, try it yourself:) or I may take points off, ask me next time.

When x ≠ 0, the expression x²/2x⁵ × 1000 simplifies to 500/x³. This is obtained by simplifying the fraction and then multiplying by 1000.

To simplify the expression (x²/2x⁵) × 1000, we can start by simplifying the fraction within the parentheses.

First, let's deal with the fraction x²/2x⁵. We can simplify it by using the rule of exponents, which states that x^m/x^n = x^(m-n) when dividing with the same base. In this case, we have x²/2x⁵, so:

x²/2x⁵ = (x²)/(2x⁵) = (x²/x⁵) * (1/2) = x^(2-5) * (1/2) = x^(-3) * (1/2).

Now, we have the fraction x^(-3) * (1/2). To simplify this further, we can rewrite x^(-3) as 1/x^3. Therefore, the expression becomes:

(1/x^3) * (1/2) = 1/(2x³).

Now that we've simplified the fraction within the parentheses, we can multiply it by 1000:

(1/(2x³)) * 1000 = 1000/(2x³) = 500/x³.

So, the expression x²/2x⁵ × 1000 simplifies to 500/x³ when x ≠ 0.

Thompson's market sells a 25 pound bag of happy chow dog food for $15.49 and a 30 pound bag of super chow dog food for $17.39 which brand is the better buy?Explain

Answers

Answer:

The better buy would be super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

Step-by-step explanation:

Happy chow is $15.49 for 25 pounds

The price per pound Happy chow=15.49/25 =$0.62

Super chow is $17.39 for 30 pounds

The price per pound of Super chow=17.39/30=$0.58

Happy chows($0.62)>Super chow ($0.58)

The better buy would be Super chow since the price per pound($0.58) is cheaper than Happy chow's $0.62 so a buyer gets the same quantity but at a cheaper price

Happy chow is $15.49 for 25 pounds

The price per pound Happy chow=15.49/25 =$0.62

Super chow is $17.39 for 30 pounds

The price per pound of Super chow=17.39/30=$0.58

If A ⊂ B, then A ∩ B = A ∪ B. always, sometimes, never

Answers

Answer:

Hence, the property:

A ∩ B = A ∪ B never hold .

Step-by-step explanation:

We are given that set A⊂B .

This means that set A is properly contained in set B.

i.e. A≠B

This means that there are some elements in set B which are not in set A.

Now we have to show whether the following property A∩B=A∪B

always, sometimes or never hold.

As A is a proper set of B.

This means that: A∩B=A ( Since A is a smaller set)

Also, A∪B=B (Since B is a bigger set)

Hence, A∩B ≠ A∪B (Since A≠ B)

The answer is never.
