Rewrite the equation below so that it does not have fractions four -4/9 times equals two over three do not use decimals in your answer please help me I’ll give you 10 points
The equation is 36 - 4x = 6.
Solution:
To write the equation without fraction.
[tex]$4-\frac{4}{9} x=\frac{2}{3}[/tex]
[tex]$\frac{4}{1} -\frac{4}{9} x=\frac{2}{3}[/tex]
The denominators must be same to add/subtract the fractions.
LCM of 1, 9 and 3 = 9.
Multiply first term by [tex]\frac{9}{9}[/tex] and [tex]\frac{2}{3}[/tex] by [tex]\frac{3}{3}[/tex] to make the denominator same.
[tex]$\frac{4\times9}{1\times9} -\frac{4}{9} x=\frac{2\times3}{3\times3}[/tex]
[tex]$\frac{36}{9} -\frac{4}{9} x=\frac{6}{9}[/tex]
[tex]$\frac{36-4x}{9} =\frac{6}{9}[/tex]
Multiply by 9 on both sides.
[tex]$\frac{36-4x}{9}\times9 =\frac{6}{9}\times9[/tex]
Both 9 in the numerator and denominator get canceled.
36 - 4x = 6
This term does not have fraction.
Hence the equation is 36 - 4x = 6.

Use the Distributive Property to express
24 + 36
Answer:
12(2 + 3)
Step-by-step explanation:
To use the distributive property, we must find a common factor between the two numbers. The greatest common factor or 24 and 36 is 12. Let's just use that. We get:
[tex]12(2+3) = 24+36[/tex]
That's our answer!
Answer:
12 ( 2 + 3 )= + 36

24 = 2 * 2 * 2 * 3
36 = 2 * 2 * 3 * 3. what they both have in common between the prime factorization of both of the numbers are 2*2*3 which is GCF and equivlent to 12.
What do you multiply -2 by to get -24
Answer:
The answer is 12
Step-by-step explanation:
Step 1: Convert words into an equation
What do you is you multiply -2 by something to get -24
-2 * something = -24
We can represent something with a variable called x.
-2 * x = -24
-2x = -24
Step 2: Solve for x by dividing both sides by -2
-2x / -2 = -24 / -2
x = 12
Answer: The number we can multiply -2 by to get -24 is 12
Lets write this into an expression.
-2x = -24
Now, lets solve for x.
~Divide -2 to both sides
-2x/-2 = -24/-2
~Simplify
x = 12

What is the remainder when x^{6}-4x^4+4x^2-10 is divided by x+3?
Answer:
431
Step-by-step explanation:
Let
[tex]p(x) = {x}^{6} - 4 {x}^{4} + 4 {x}^{2} - 10[/tex]
We want to find the remainder when this polynomial is divided by x+3.
We use the remainder theorem.
Which says that, when p(x) is divided by x-a, the remainder is p(a)=R.
Therefore the remainder when p(x) is divided by x+3 is p(-3).
[tex]p( - 3) = {( - 3)}^{6} - 4 { (- 3)}^{4} + 4 {( - 3)}^{2} - 10[/tex]
We evaluate:
[tex]p( - 3) = 729 - 4 (81)+ 4 {( 9)} - 10[/tex]
We multiply to get;
[tex]p( - 3) = 729 - 324+ 36- 10[/tex]
We simplify to get:
[tex]p( - 3) =431[/tex]
Therefore the remainder is 431

The volume of the smaller room is B. 768 cubic feet.
Step-by-step explanation:
Step 1:
The entire length for both rooms is 20 feet. As the large room has a length of 12 feet, the length of the smaller room is [tex]20-12=[/tex] 18 feet long.
The width of the prism is 12 feet and a height of 8 feet.
The volume of a rectangular prism is determined by multiplying its length, its width, and its height.
The small room's length = 8 feet,
The small room's width = 12 feet, and
The small room's height = 8 feet.
Step 2:
The volume of a rectangular prism [tex]= (l)(w)(h).[/tex]
The volume of the smaller room [tex]= (8)(12)(8)= 768.[/tex]
So the volume of the smaller room is 768 cubic feet which is option B.
Given the equation 3x+9y=-8,write a second linear equation to create a system that has exactly one solution.
A second linear equation that forms a system with exactly one solution with 3x+9y=-8 could be y = -2x + 4, as it has a different slope and y-intercept, ensuring the lines intersect at one point.
Explanation:To create a system of equations with exactly one solution, you need to write a second linear equation that has a different slope than the first equation (3x+9y=-8) but does not share any points with it. The slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, will be used to construct our new equation.
Given the slope-intercept form y = 9 + 3x as an example, we see that the slope (m) is 3 and the y-intercept (b) is 9. To ensure our second equation has only one solution when paired with the first equation, we can select a different slope and y-intercept. For instance, an equation such as y = -2x + 4 would suffice, as it has a different slope (-2) and intercept (4), ensuring that the two lines will cross at exactly one point on the graph.
In summary, the original equation 3x+9y=-8 and the second equation y = -2x + 4 when graphed will intersect at exactly one point, forming a system of linear equations with one solution. This process involves selecting different values for the slope and y-intercept to make sure the lines are not parallel and do not coincide.
is y = 2x + 4 a proportion relationship
Answer: No
Step-by-step explanation:
When graphing [tex]y=2x+4[/tex] it comes out not being a proportion relationship.
*(revised answer)
So the answer is no, a proportional relationship has to run through the origin, and y=2x+4 has a y-intercept of 4, meaning that even though x increases when y does, the y-intercept means that this equation is not a proportional relationship.

Answer:
48.30 kph
Step-by-step explanation:
55mph - 88.50kph
1mph - 1.61 kph
30 mph - 48.30 kph
Horses can reach speeds of 55 mph (approximately 88.50 kph), while most donkeys top out at 30 mph over short distances.
A conversion factor is a number that is used to multiply or divide one set of units into another. The acceptable factor to an equivalent value must be utilized when a conversion is crucial.
Given that,
Horses can reach speeds of 55 mph (approximately 88.50 kph).
Most donkeys have a top speed of 30 mph over short distances.
Here the top speed of most donkeys is asked.
To convert miles per hour (mph) to kilometers per hour (kph),
Use the conversion factor of 1.60934.
Calculate the top speed of most donkeys in kph:
Given: Top speed of most donkeys = 30 mph
Conversion: 30 x 1.60934
≈ 48.28 kph

7. The ratio of wins to losses for Loyola basketball was 4 to 1. If the team played 30 games, how
many wins and how many losses did they have? Show your work.
Answer:
24:6
Step-by-step explanation:
It is 4 to 1. The ratios added up is 5. So 30 divided by 5 is 6. So 1 (the ratio) is 6 games. 4x6=24. So the new ratio is 24 to 6. 24 wins and 6 losses.
The team won 24 games and lost 6, calculated by first solving for x in the equation 5x = 30 and then applying the 4:1 win-to-loss ratio.
If the ratio of wins to losses for Loyola basketball is 4 to 1, and they played 30 games, we want to find how many of those games were wins and how many were losses. Let's say the number of wins is 4x and the number of losses is x. According to the ratio, there are 4 wins for every loss, which makes the total number of games 4x + x = 5x.
Since we know 5x is 30 games, we can solve for x to find out the number of losses. Dividing 30 by 5, we get x = 6. That's the number of losses. To find the number of wins, we multiply 4 times the number of losses (4x), which gives us 4 * 6 = 24 wins.

We can rewrite it as:
[tex]y = \frac{ \sin(x) }{ \cos(x) } [/tex]
This graph has vertical asymptotes at where the denominator is zero.
[tex] \cos(x) = 0 \\ \implies \: x = \frac{\pi}{2} \: or \: \frac{3\pi}{2} [/tex]
The correct options are : (b) [tex]\( x = \frac{\pi}{2} \)[/tex] and (d) [tex]\( x = \frac{3\pi}{2} \)[/tex]
The asymptotes of the tangent graph are the vertical lines where the tangent function is undefined. The tangent function, [tex]\(\tan(x)\)[/tex], is undefined where the cosine function is zero, which happens at:
[tex]\[ x = \frac{\pi}{2} + k\pi \quad \text{for integer values of } k \][/tex]
So, let's check each given value to see if it fits this form.
1. [tex]\( x = \frac{\pi}{4} \)[/tex]
[tex]\[ \frac{\pi}{4} \neq \frac{\pi}{2} + k\pi \][/tex]
This is not an asymptote.
2. [tex]\( x = \frac{\pi}{2} \)[/tex]
[tex]\[ \frac{\pi}{2} = \frac{\pi}{2} + 0 \times \pi \][/tex]
This is an asymptote.
3.[tex]\( x = \pi \)[/tex]
[tex]\[ \pi \neq \frac{\pi}{2} + k\pi \][/tex]
This is not an asymptote.
4. [tex]\( x = \frac{3\pi}{2} \)[/tex]
