3y + 6 = 12

Answers

Now that you have the problem set up you need to combine like terms. There is only one “y” so you leave that alone. There two numbers that are by themselves, so you would combine them. The only thing is that since 6 is on the opposite side you need to somehow put it to the other. What’s the opposite of adding? Subtracting! Now you have 3y=6. Okay so now you need to get y by itself. You divide three where 3 is so 3/3=1 so now the y is by itself. Then divide 6/3 to get 2!

Answer:

 = 2

Step-by-step explanation:

3  +  6  =  1 2

subtract 6 from both sides of the equation

3  +  6  −  6  =  1 2  −  6

3  =  1 2  −  6

3y/3 = 6/3

y = 6/3

y = 2

As the world I’m heading towards and matching up to is getting bigger  

It makes me feel an emptiness somehow  

What part it is, even if the shape is maybe like this  

Even when myself can’t come to know it  

As if solving up the scattered pieces  

We are matching up our stories  

Inside the empty spot in my heart, there’s a piece called you taking place  

I just know it at first glance I saw you  

You’re my missing puzzle piece  

Finally I solved it  

You filled every piece of my heart, even the scarred part of it to the fullest  

And somehow, you’ve become my everything  

My missing puzzle piece  

The fact that I have a flaw,  

The truth that I am imperfect All of it makes me feel small  

But in between those gaps  

We can fill one another with it  

So I don’t even realized that it was empty  

“Hello, it’s been so long, isn’t it?”  

The small piece that I put in my pocket and carry around everywhere  

Please be with me so it can be fuller and prettier  

After I met you, I’m able to draw a bigger picture  

You’re my missing puzzle piece  

Finally I solved it  

You filled every piece of my heart, even the scarred part of it to the fullest  

And somehow, you’ve become my everything  

My missing puzzle piece  

My missing puzzle piece  

More than having everything, Not losing that one thing is more important  

Through you, I came to know that  

You’re my missing puzzle piece  

Very dazzling  

It becomes one scene inside the world that I’ve been trying to put together alone

Like the hands that are interlocking tight together,

Because without you, it can’t be completed

Step-by-step explanation:

From the question, we are informed that Steve sold 252 fruit basket for a school fundraiser while Evie aold 25 fruit baskets for each 100 baskets that Steve sold. This means that Evie sold 25/100 = 1/4 of what Steve sold.

Therefore, the number of fruit baskets sold by Evie will be:

Linear equation

Step-by-step explanation:

Given

The attached

Required

Determine the type of function

We start by checking for linear function

A linear function is such that:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

The above represents the slope

For any pair of coordinate points, the slope must be constant.

We have:

[tex](x_1,y_1) = (-3,-16)[/tex]

[tex](x_2,y_2) = (-2,-13)[/tex]

The slope (m) is:

[tex]m = \frac{-13-(-16)}{-2-(-3)}[/tex]

[tex]m = \frac{-13+16}{-2+3}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m = 3[/tex]

Take another pair:

[tex](x_1,y_1) = (-1,0)[/tex]

[tex](x_2,y_2) = (-10,-7)[/tex]

The slope (m) is:

[tex]m = \frac{-7-(-10)}{0-(-1)}[/tex]

[tex]m = \frac{-7+10}{0+1}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m = 3[/tex]

The slope remains constant

Hence, it is a linear function

Suppose that Dr. Vergara makes a free throw with probability 0.8 and, independently, Dr. Agor makes a free throw with probability 0.4. They each attempt one free throw. (a) Given that only one of them made a free throw, what is the probability that Dr. Agor made his free throw

Answers

Answer:

The probability that Dr. Agor made his free throw is 40%.

Step-by-step explanation:

Given the fact that Dr. Agor usually converts his free throws with a probability of 0.4, to determine the percentage of probability that he will convert his free throw, the following calculation has to be performed:

0.4 x 100 x 1 = X

40 x 1 = X

40 = X

Therefore, Dr. Agor has a 40% chance of making his free throw.

40%

Compute the distance from y to the line through u and the origin.

Answers

Answer:

2√5

Step-by-step explanation:

Given the coordinates y(3,1) and u(8,6)

We are to find the distance between the two coordinates

Using the formula:

D = √(x2-x1)²+(y2-y1)²

D = √(8-3)²+(6-1)²

yu = √(5)²+(5)²

yu = √25+25

yu = √50

yu = 2√5

Hence the distance between the two coordinates is 2√5

Eva bought one share of a company's stock for $42 on Monday. Over the next two days, the value of the stock changed, as described below. •change in value on Tuesday: -$15 • change in value on Wednesday: +$15 which number line best represent the value of Eva’s stock over the three-day period?

Answers

Answer:

The first number line is correct.

Step-by-step explanation:

To find the number which best represents Eva's stock, we look into the text, and find the changes:

Monday: Stock bought at $42.

Tuesday: Change of -$15, so now it is worth $42 - $15 = $27

Wednesday: Change of +$15, so now it is worth $27 + $15 = $42

The number line which represents the decrease, and then the increase, is the first one.

The equation c = 2.5t represents the cost, c, for t tickets to the school play. Does a value of 3.5 for t make sense in this situation? Explain your reasoning.

Answers

Answer:

No, a value of 3.5 for t does not make any sense because it should be a discrete value.

Step-by-step explanation:

Given equation is:

c = 2.5t

Here,

c = Cost

t = number of tickets

Now,

The value of t cannot be a decimal number but it must be a whole number. Because half ticket cannot be sold.

Hence,

No, a value of 3.5 for t does not make any sense because it should be a discrete value.

Answers

Answer:

D. [tex] x = \frac{5*\sqrt{2}}{2} [/tex]

Step-by-step explanation:

Reference angle = 45°

Length of Opposite side = x

Hypotenuse length = 5

Applying trigonometric ratio, we have:

[tex] sin(45) = \frac{x}{5} [/tex]

Multiply both sides by 5

[tex] 5*sin(45) = \frac{x}{5}*5 [/tex]

[tex] 5*sin(45) = x [/tex]

[tex] 5*\frac{1}{\sqrt{2}} = x [/tex] (sin 45 = 1/√2)

[tex] \frac{5}{\sqrt{2}} = x [/tex]

Rationalize

What percent of 20 is 15?

The number after "of" goes on the bottom of the fraction and the number after "is" goes on the top.

PLEASE SOMBODY DO STEP BY STEP .

Answers

15 is 75 % of 20

20/15 = 100/75

Answer:

75%

Step-by-step explanation:

Well lets set this up.

You want to find what percent of 20 is 15.

So to do that you can make it a fraction.

The numerator is what is being divided and the denominator is what you want it divided by.

So you want 15 divided by 20

So 15 is numerator

20 is denominator.

[tex]\frac{15}{20}[/tex]

A fraction is basically a division problem so now all you need to do is divide 15 by 20.

If you do that you should get a decimal answer of 0.75

To make a decimal a percentage all you have to do is multiply it by 100.

0.75 * 100

[If you do not have a calculator on you an easy way to do this is look at how many zeros 100 has and move the decimal right that many times]

75

Now just add that percent sign and you have 75% as your answer!

If you need further assistance please don't be afraid to reach out. I hope this helps!
