a. 10
b. -10
c. 90
d. -90

Answer:

C

Step-by-step explanation:

It isn't B because the point does not start at 600 and it is not A because it shows the entire decrease of the mass in one millennium. The correct answer is c.

Answer:

a= 7.5%12.58= 0.9435 round 0.94+12.58= 13.52

b= 31.50 divided by 19.00= 1.65789474 round 1.66

c= (14.25 x 18)+ (5.5%250)

            l                     l

Answer:

See below

Step-by-step explanation:

1. Perimeter is the sum of all sides.

(x+4)+(x+4)+(2x-8)+(2x-8)

(x+4)+(x+4) = 2x+8

(2x-8)+(2x-8) = 4x-16

2x+8 + 4x-16 =

6x-8

2.

4x-5 Sat

3x-10 Sun

(4x-5)-(3x-10)

4x-3x = x

-5--10 = 5

x+5

3. Total, so add

8x+16 Sat

7x-9 Sun

(8x+16) + 7x-9

8x+7x=15x

16-9=7

15x+7

Answer:

\({ \bf{ - \frac{2}{5} x - 9 < \frac{9}{10} }} \\ \\ { \tt{ - 2x - 45 < \frac{9}{2} }} \\ \\ { \tt{ - 2x < \frac{99}{2} }} \\ \\ { \tt{x > - \frac{99}{4} }}\)

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

Answer: $138.75

Step-by-step explanation:                                                                                               The answer to this question would be: $138.75

In this question, for item with $80 total price the tax is $6 which mean the actual price (before tax) is $80-$6= $74.

That mean the ratio of the tax: item= 6:74

Then for the second item, if the tax is $11.25 then the price before tax would be: $11.25* 74/6= $138.75

Answer:

9) 25 people

Step-by-step explanation:

First, you have to pay off the rent for the party from the $$$ you have

600-150=450

Then, use $$$ for each person to divide the leftovers to see how many people you can have.

450/18=25

I hope this helps!

Please mark brainliest!

Answer:

Question 1: \(w=-3\)

Question 7: \(x=8\)

Question 9: \(x=25\), or 25 people.

Question 11: \(-5\)

Step-by-step explanation:

Hey! Alright, this is a lot of work. And I mean, a lot for one post. So, instead of doing all the work here. I am going to do one question of each section and hopefully you'll be able to use those as a guide.

Question 1: \(-5(2w+1)=25\)

For this question, we are trying to solve the equation. Now what does that mean? What this means is we are typically looking for a letter (variable) to solve for. In this case, we are trying to figure out the value for w. How do we do that? Well, let's start by isolating the w the best we can. It would look like such:

\(\frac{-5(2w+1)}{-5}=\frac{25}{-5}\) - We remove the -5 on the left side by dividing it.

\(2w+1=-5\)

\(2w+1-1=-5-1\) - Removing 1 from both sides to get rid of 1 on the left.

\(2w=-6\)

\(\frac{2w}{2}=\frac{-6}{2}\) - Divide both sides by 2 to isolate w.

\(w = -3\)

Therefore, when we solve the equation, we get \(w=-3\). In all the other questions till question 6, when you're solving for the equation, it's usually solving for the variable (the letter) in the equation. In the example, I just showed you, there was only one instance of w involved. If there are multiple numbers with a variable, you do something called collecting like terms, which is essentially just adding and/or subtracting numbers with the variable only. Keeping numbers by itself and numbers with the variable separate until the very end when you divide the number with the variable.

Question 7:

For this question, it's better to start with what we know. We know for a fact that the entire perimeter of the triangle is 22 units. We also know that one side is 5 and another side is \(x+1\). Now we just have to figure out for the unknown side x. In order for us to do this, we can put it in terms of an equation! Now, when we are finding the perimeter, we're always going to be adding side lengths because we find the perimeter by adding up all the sides. The formula would look like this:

\(22=x+1+5+x\)

\(16=2x\) - Moved 1 and 5 over to the other side and subtracted it from 22 and combined x.

\(8=x\)

Here, we get \(x=8\). To check our work, we can simply plug our answer back into x and see if we get a total perimeter of 22. It would look like this:

\(5+8+1+8=22\)

And we indeed get 22!

Question 9:

For word problem questions, we need to pay attention to the information within the problem. In this question, we have a restaurant that charges $150 to rent the space. The food for each person costs $18 and we have $600 to spend in total. The question asks how many people can come to the party given $600 in total to spend. From here, we need to know the idea of fixed value and variable value. To put it simply, a fixed value is something that cannot be changed no matter the circumstances and, in this case, that is $150 because we need to rent the space. A variable value is something that can be change due to quantity usually. In our problem, we have $18 per person because that value can go up depending on how many people show up. We let x represent the amount of people coming to the party and y be the total cost. So, we set up our equation as:

\(y=18x+150\)

Given our question, we know how much our total cost is going to be ($600), so it is going to look like this:

\(600=18x+150\)

Now it's back to solving variables again! We evaluate as such to find out how many people can attend and that's:

\(600=18x+150\)

\(450=18x\)

\(\frac{450}{18} =\frac{18x}{18}\)

\(25=x\)

Based on our calculations, we can invite 25 people to the party if we spend $600 in total.

Question 11:\(a-2-(3+a)\)

Now, this question is going to be different compared to the first 6 questions. This question asks you to simplify not solve. All we're doing here using the steps to solve the variable, but not dividing the coefficient to isolate x. So, in this case, it would look like this:

\(a-2-(3+a)\)

\(=a-2-3-a\) - Distributing the negative into the bracket.

\(=a-a-2-3\) - Moving over the terms to make it easier for us to evaluate.

\(=-2-3\)

\(=-5\)

In this question, we managed to cancel out the whole variable value altogether but in the next few questions, it will be in the format of one coefficient and a variable that is adding or subtracting another number.

Hope this helps you! If there are any question, feel free to let me know in the comments and I will help you out!

Answer:

525

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer: ETU

Step-by-step explanation:

When you are writing a similarity statement, you must put the letters of both triangles in the same order. In other words, you must make the first letter of the first triangle match with the first letter of the second triangle, and so on.

In this figure, \(\angle K\cong\angle E\), \(\angle L\cong\angle T\), and \(\angle KUL\cong\angle EUT\). Hence,

\(\triangle KLU \sim \triangle ETU\)

Since K is first, E is also first, as ∠K matches to ∠E. Since L is second, T is also second, as ∠L matches to angle ∠T.

Answer:

Ken, Leon, and Mark collect seashells as a hobby. Ken has (3x - 5) seashells, Leon has (2x +1) seashells, and Mark has (0.25x + 7) seashells. a. Write an expression for the total number of seashells they collected.

The answer:

Ken has 5 shells, Leon has 2 shells, Mark has 1.50 shells

how do we know:

because the 5 is negative we have -5 + -5=0 because negatives only go up by subtracting so 0+-5 is 5.

because the 1 is positive we can do 1+1 as were doing 2x1 so 1+1=2.

because we are doing 0.25x7 we need to know that we can flip the problem so we get 7x0.25. this makes things easy for you and me, we already know that 4 0.25's make 1 and we also know that 0.25+0.25 is 0.50 and 1 + 0.50 is 1.50 or just 1.5

hope this helps!
