How many solutions does the equation have? 5(n–2)=5n–10

A.) 1 solution

B.) no solutions

C.) many solutions

Answers

C) many solutions

But to be precise, there are INFINITELY many solutions.

[tex]5(n-2)=5n-10\\\\5n-10=5n-10\\\\0=0\\\\x\in\mathbb{R}[/tex]

Final answer:

The equation 5(n–2)=5n–10 has many solutions because any value of n will satisfy the equation as both sides of the equation match exactly.

Explanation:

The equation given is 5(n–2)=5n–10. Let's solve this step-by-step.

Distribute 5 through the parentheses on the left side of the equation: 5n - 10 = 5n - 10. As you can see, both sides of the equation match exactly, meaning that any value for n will make the equation true.

So, the answer is C.) many solutions, because any value of n will satisfy this equation.

the largest alligator ever caught in Mississippi weighed 727 pounds?

Answers

The answer is false. The alligator caught in Mississippi actually weighed 766.5 pounds.

Final answer:

The largest alligator ever recorded and taken in the state of Mississippi weighed 727 pounds. This is an exceptional case, as alligators usually weigh less.

Explanation:

Yes, the largest alligator ever recorded and caught in the state of Mississippi weighed 727 pounds. This monumental creature stands as a testament to the potential size that members of the alligator species can achieve under optimal conditions. It's always imperative to understand that different species have varied weight standards, and this is no exception when it comes to alligators. While 727 pounds may seem extraordinarily large, it's important to note that it is an extreme and not the norm for the species.

heba ate 1/12 of a box of cereal now the box is 3/4 full what fraction of a full box was there before heba ate it

Answers

Now box is 3/4 full


3/4 = 3/4*1


3/4 = 3/4 * 3/3 = 9/12


Box is 9/12 full after heba ate 1/12 of a box of cereal


Initial fraction will be 9/12+1/12


=10/12= 5/6

Answer:

5/6.

Step-by-step explanation:

If Heba ate 1/12 of a box of cereal and the box is now 3/4 full, then before she ate the box is 3/4 plus the 1/12 (because, in the "before" situation she hasn't eaten yet). So, we need to add the "now" quantity and the quantity eaten:

[tex]\frac{3}{4}+\frac{1}{12} = \frac{10}{12} = \frac{5}{6}.[/tex]

Then, before she ate the cereal, the box is 5/6 full.

18x^2-2 factor completely

Answers

Here is your answer to your question

The factored form of [tex]\(18x^2 - 2\)[/tex] is [tex]\({2(3x - 1)(3x + 1)}\)[/tex].

To factor the expression [tex]\(18x^2 - 2\)[/tex] completely, we first notice that [tex](18x^2\))[/tex] and [tex]\(2\)[/tex] share a common factor of [tex]\(2\)[/tex]. We can factor out this common factor to simplify the expression:

[tex]\[18x^2 - 2 = 2(9x^2 - 1)\][/tex]

Now, we recognize that [tex]\(9x^2 - 1\)[/tex] is a difference of squares. It can be factored as [tex]\((3x)^2 - 1^2\)[/tex], which follows the pattern [tex]\((a^2 - b^2) = (a - b)(a + b)\)[/tex].

So, applying this pattern, we have:

[tex]\[9x^2 - 1 = (3x)^2 - 1^2 = (3x - 1)(3x + 1)\][/tex]

Therefore, the expression \(18x^2 - 2\) factors completely as:

[tex]\[18x^2 - 2 = 2(9x^2 - 1) = 2(3x - 1)(3x + 1)\][/tex]

Are angles 2 and 5 vertical angles, linear pairs or neither? Thank you :)

Answers

Vertical angles. Vertical angles are two angles that equal the same and are directly across from each other. In this case, if you find the value of 2 then 5 would be the same.
Final answer:

Without more information or a diagram showing the arrangement of the angles, we can't accurately determine if angles 2 and 5 are vertical angles, linear pairs, or neither. Vertical angles are those opposite each other when lines intersect and are always equals, while a linear pair of angles add up to 180 degrees and share a vertex and a side.

Explanation:

To determine if angles 2 and 5 are vertical angles, linear pairs, or neither, we need to know the positional arrangement of these angles.

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in degree.

A linear pair of angles is formed when two angles add up to 180 degrees and they share a vertex and a side.

Without a diagram or more context, it's impossible to determine the relationship between angles 2 and 5. Please provide more information or a diagram to help identify the relationship between these angles.

5b+4+10=-2

Answers

5b+4+10=-2

5b+14=-2

5b+14-14=-2-14          1)  subtract 14 from both sides

5b=-16

5b/5=-16/5                 2) divide by 5 on both sides

b=3 & 1/5

The answer is b = -3.2.


First, you have to add 4 and 10 together to get 14. Then, you subtract 14 from 14 and negative 2. You will get negative 16 because since the 2 is already a negative, you would just be adding two negatives. Next, the equation should look like this: 5b = -16. Now, you would divide by 5 on each side and your answer should be b = -3.2. Hope this helps!

Stu wants to join a gym. Fit-Place charges a $135 startup fee and then $35 per month. The Factory has no startup fee but charges $60 per month. Create a table showing the total cost for the first 8 months. Determine the month at which the total cost is the same.

Answers

I don't know the answer use a calculater

Answer:

Fit-Place charges a $135 startup fee and then $35 per month.

Means the cost here will be based on the equation : [tex]135+35x[/tex] where x is the number of months.

The Factory has no startup fee but charges $60 per month. Here the equation will be [tex]60x[/tex], where x is the number of months.

Table ;

Months              1          2          3        4         5        6          7        8

Fit-Place          170      205     240     275     310     345    380   415

The Factory     60      120        180     240    300    360   420    480

The total cost will be same in:

[tex]60x=135+35x[/tex]

=> [tex]60x-35x=135[/tex]

=> [tex]25x=135[/tex]

x = 5.4 rounded to 5 months.

Now we can see that the total cost will be same in almost 5 months.

Write two numbers that are greater than 32.46 and less than 32.56 then the difference of your two numbers

Answers

Answer:

32.48 and 32.50 is the numbers which are more than 32.46 and less than 32.56 and there difference is 0.02

Step-by-step explanation:

We have given two numbers 32.46 and 32.56

We have to find two numbers which are greater than 32.46 but less than 32.56

The number 32.48 is greater than 32.46 and less than 32.56

And other number 32.50 is greater than 32.46 and less than 32.56

Now we have to find the difference of these two numbers

So difference = 32.50 - 32.48 = 0.02

The two numbers that are greater than 32.46 and less than 32.56 are 32.48 and 32.54.

The difference between the two numbers is 0.06.

What is the difference of your two numbers?

32.46 and 32.56

The numbers greater than 32.46 and less than 32.56 are:

32.47, 32.48, 32.49, 32.50, 32.51, 32.52, 32.53, 32.54, 32.55

We can choose any two numbers from the listed

to do so, divide both sides by 10 to get rid of the 10.

once you divide both sides by 10, x is on its own, and you have the solution to your equation, x = -8!

to check your work you can plug the value for x into the original equation and solve.

tax

164.25 * 5% = 8.21

164.25 * 2% = 3.28

sum of the tax

8.21 + 2.47 +3.28 =

13.96

your answer is C

Final answer:

To find the total tax on Edward Taylor's purchases, sum the cost of all items ($164.25), multiply by the combined tax rate of 8.5% to get the total tax in dollars ($13.96125), and round to the nearest cent, resulting in $13.96. So, option C is correct.

Explanation:

To determine the total amount of tax on Edward Taylor's purchases, we need to sum up the cost of all items purchased and then calculate the combined sales tax. Edward bought two shirts for $17.95 and $27.50, a jacket for $94.20, and two ties at $12.30 each. Here are the steps taken:

Calculate the sum of the purchases: $(17.95 + 27.50 + 94.20 + 12.30 + 12.30) = $164.25.

Combine the tax rates: (state tax at 5% + county tax at 1.5% + city tax at 2%) = 8.5% total.

Convert the tax rate to a decimal: 8.5% = 0.085.

Multiply the total cost of purchases by the tax rate: $164.25 * 0.085 = $13.96125.

Round the tax to the nearest cent: $13.96.

Therefore, the total amount of tax on his purchases is $13.96. So, option C is correct.
