Drag the correct steps into order to solve the equation -3x – 6 = 18 for x.
Answers
The solution to the linear equation -3x - 6 = 18 is x = - 8
What is the solution of the equation?The solution of the linear equation is calculated as follows;
The given linear equation;
-3x - 6 = 18
Move the constant term to the other side of the equation.
-3x - 6 + 6 = 18 + 6
-3x = 24
Divide both sides of the equation by the coefficient of x (-3) to isolate x.
(-3x) / (-3) = 24 / (-3)
x = -8
Thus, the solution to the linear equation -3x - 6 = 18 is x = - 8

I am confused on where to go from here to solve the equation. Pls help.
Answers
Use cos2x =1-2sin^2x
1+sinx- (1-2sin^2x) = 1+ sinx -1+2sin^2x
=sinx+2sin^2x=sinx(1+2sinx)
Therefore
Either sinx=0 or 1+ sin2x =0

Then, simplify the "z"s Then, subtract 5 from both sides
-3z = 3
Then, divide both sides by -3
z = -1
To check
-1 + 5 - 4(-1) = 8
-1 + 5 + 4 = 8 -1 + 9 = 8

the width of a rectangle is 12 cm less than the length the perimeter is 156 cm. Find the length and width
Answers
L+L+W+W=perimeter
2L+2W=perimeter
We can put the value of the perimeter into this
2L+2W=156cm
Next, we have to make sure all the terms (letters) are the same so we can solve it. This means we have to rewrite either the length or width in terms of the other.
We know the width is 12cm less than the length, which is the same as saying L-12
Then we substitute this into the equation and solve L
2L+2(L-12)=156
2L+2L-24=156
4L-24=156
4L=180
L=45cm
Next we use this value to find W.
45-12=33
W=33cm

If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5
1st trip- $115
And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5
2nd trip- $115

Step-by-step explanation:
An architect notices that the scale on a blueprint he is using has been torn off.
However, he sees that a 12.5-ft. wall that has been built is 5 in. long on the blueprint.
Let the scale be x
[tex]\frac{5}{12.5} =\frac{1}{x}[/tex]
So, scale = [tex]x=\frac{12.5}{5}[/tex] = 2.5

An item that is normally sells for $130 is marked down 30%. What is the sale price
Answers
To find the sale price of an item that is normally $130 with a 30% markdown, calculate the discount amount ($39) and subtract it from the original price to get a sale price of $91.
The question asks to calculate the sale price of an item after a 30% markdown. To determine the sale price, you have to first calculate the discount amount and then subtract it from the original price of the item. Here's how you do it:
Find the discount amount: original price x discount rate.Subtract the discount amount from the original price to get the sale price.For an item that is normally sold for $130 and is marked down 30%, the sale price can be calculated as follows:
Discount amount: $130 x 0.30 = $39.Sale price: $130 - $39 = $91.Six people can sit at each table.

The boat travels x miles per hour from one island to another island in 2.5 hours. The boat travels 5 miles per hour faster on the return trip of 2 hours. What is the distance between the island?
Answers
The distance is the same so, 2.5 multiplied by x = 2×(x+5).
It took 2.5 hrs to get there and 2 hrs to return. Now all we have to do is solve.
2.5*x = 2x + 10
.5x = 10
x=20
Therefore, the distance between islands is 2.5 × 20 = 50 miles.

Perform the indicated operation . Round the result to the nearest tenth and then to the nearest hundredth . Separate your answers by a comma . -49.256 + 17.197
Answers
Final answer:
By adding the two numbers and rounding, we first get -32.1 for the rounding to the nearest tenth and then the same result, -32.1, when rounding to the nearest hundredth.
Explanation:
To perform the indicated operation and round the result first to the nearest tenth and then to the nearest hundredth, we begin by adding the two numbers: -49.256 + 17.197. The sum of these numbers is -32.059. To round to the nearest tenth, we look at the hundredths place, which is 5, so we round up, resulting in -32.1. Next, to round to the nearest hundredth, we consider the thousandths place, which is 9, so we again round up, but since we're already at 9 in the hundredths place, the result remains -32.1.

theoretical probability and experimental probability are the same true or false?
Answers
Answer:
FALSE
Step-by-step explanation:
The statement 'theoretical probability and experimental probability are the same' is generally false. Theoretical probability is what we expect to happen, while experimental probability is based on actual results from experiments. With more trials, these two probabilities tend to get closer, thanks to the Law of Large Numbers.
Explanation:The statement 'theoretical probability and experimental probability are the same' is generally false. Theoretical probability is defined as the number of desired outcomes divided by the number of possible outcomes, assuming that all outcomes are equally likely. It is what we expect to happen in an experiment.On the other hand, experimental probability is the proportion of times an outcome occurs based on actual experimental results. In other words, it is the data observed from repeated trials of an experiment. It's worth noting that with an increasing number of trials, experimental probability tends to get closer to theoretical probability, in accordance with the Law of Large Numbers.Learn more about Probability here:https://brainly.com/question/22962752

which is a disadvantage of purchasing and owning a home?
Answers
The answer to your question is,
B. Homeowners pay additional property taxes
-Mabel <3
Owning a home can lead to a lack of flexibility, high maintenance costs, and financial risks associated with changes in the housing market.
Explanation:A significant disadvantage of buying and owning a home is the commitment and reduced flexibility compared to renting. When you purchase a home, it becomes a major part of your portfolio, any change in the housing market can directly affect your financial status. Not to mention, if you need to move for a career opportunity or a change in life circumstances, it can be challenging to sell the house, especially if the market conditions are unfavorable.
Furthermore, home ownership often comes with substantial maintenance costs and responsibilities. Unlike renting, where the landlord typically handles maintenance tasks, as a homeowner, these responsibilities and costs are up to you. This can include routine tasks such as gardening and cleaning, to significant unexpected costs like roof replacement or plumbing issues.
Additionally, despite the potential financial return of selling the house in the future for more than you paid for it, this is not guaranteed. The housing market can fluctuate and you may not always make a profit on the resale of your home.
