Answer:
A. x=1, y=3
Step-by-step explanation:
you have to isolate y in the bottom equation in order to put it into the top equation. heres what i did:
we will start with the bottom equation, x+y=4. then, subtract x on both sides of the equation. this will isolate y. now, we have the equation; y=4-x.
next, we are going to substitute our new bottom equation in where y is on the top. it looks like this: 2x+(4-x)=5. then, we are going to get rid of the parenthesis, so our equation is: 2x+4-x=5. to solve this, we have to combine like terms, so we will combine the x terms: x+4=5. now, isolate the variable. to do this, we have to take away 4 from each side so we can get x alone: x=1.
so now that we have a value for x, we can use that to find y. we can actually substitute our x-value into the bottom equation to make it easier: 1+y=4. next, we have to isolate the variable, which is y. this gives us the final answer: y=3.
i hope that this explanation helped with your struggles, it took me awhile to type out and i really tried hard. stay safe and good luck with your class!

Leonard brought 4 liters of orange juice. How many mililiters of juice does he have?
Answer:
4+x
Step-by-step explanation:
4 and however much juice he had before. there is not enough information to answer this question with certainty.
Leonard has 4000 milliliters of orange juice.
To convert liters to milliliters, we need to use the conversion factor between these two units. There are 1000 milliliters in 1 liter.
Leonard brought 4 liters of orange juice.
To find out how many milliliters of juice Leonard has, we multiply the number of liters by the conversion factor:
[tex]\[ 4 \text{ liters} \times 1000 \text{ milliliters/liter} = 4000 \text{ milliliters} \][/tex]
Therefore, Leonard has 4000 milliliters of juice.

How to Factor -6x-18y
Answer:
-6 (x + 3y)
Step-by-step explanation:
You can't factor out any variables in this case so you should look towards factoring out a number
To fully factor, you find the greatest common factor between terms and extract that, placing it on the outside of the parenthesis.
So you rewrite -18y as -6 times 3y and rewrite -6x as -6 times x.
The factored form of expression (- 6x - 18y) by using GCD (greatest common factor) and factorization method is ''- 6 (x + 3y)''
Given that,
Factor the expression (- 6x - 18y)
Used the concept of GCD (greatest common factor) and factorization method to find the factor.
Here, the expression is,
- 6x - 18y
Since, GCD of 6 and 18 = 6
Hence, take 6 as a common term,
- 6x - 18y
= - 6 (x + 3y)
Therefore, the factor form of expression is ''- 6 (x + 3y)''

Please factor b^2+36=0
Answer:

b=+√36
Step-by-step explanation:
b^2+36=0
Substrate 36 from both sides
b^2=-36
Square root both sides
b=+or -√-36
So b=+√-36
Or b=-√-36
The quadratic equation [tex]b^2[/tex] + 36 = 0 does not factor into real numbers due to the presence of a negative constant, but it factors over the complex numbers as (b + 6i)(b - 6i).
The equation [tex]b^2[/tex] + 36 = 0 is a quadratic equation of the form a[tex]x^2[/tex] + bx + c = 0, where a is 1, b is 0, and c is 36. To factor this equation, we first need to move 36 to the other side to set the equation to zero, resulting in [tex]b^2[/tex] = -36. This equation does not factor into real numbers because the square of a real number cannot be negative.
However, we can factor it over the complex numbers as (b + 6i)(b - 6i) = 0 where i is the imaginary unit.

Four sizes of scaled text are shown. Four rows of text and numbers. The first row contains a question mark followed by the phrase Website text size. The next row contains the number one followed by the phrase Website text size, but smaller than the previous row. The third row contains the number zero point nine three seven followed by the phrase Website text size, but smaller than the previous row. The fourth row contains the number zero point eight seven eight followed by the phrase Website text size, but smaller than the previous row. What is the unknown scale size? Enter your answer as a decimal in the box. Round only your final answer to the nearest thousandth.
Answer:
1.067 would be the answer your looking for in this question.
The unknown scale size is approximately 0.878.
Explanation:The unknown scale size can be determined by comparing the sizes of the text in each row. We can observe that each row represents a smaller size than the previous row. The first row has a text size of 1, the second row has a smaller text size, the third row has an even smaller text size, and the fourth row has the smallest text size. Therefore, the unknown scale size is between 0.878 and 0.937.
To find the exact scale size, we can estimate the last decimal place. Since the space between the third and fourth small tick marks is divided into ten equal parts, we can estimate the hundredths place to be 3. Therefore, the unknown scale size is approximately 0.878.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The number of different groups of three people that can be selected to fill the positions is 970,200.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that there are 100 applicants applying for three equal cosmetology positions.
Now, if a person takes up a position the same person can not take the other position, therefore, only 99 people will be left for the second position.
The same will happen with the third position, therefore, there will be only 98 people that can take the third position.
Therefore, the number of different groups of three people that can be selected to fill the positions is,
Number of different groups
= Number of applications to feel the first position × Number of applications to feel the second position × Number of applications to feel the third position
= 100 × 99 × 98
= 970,200
Hence, the number of different groups of three people that can be selected to fill the positions is 970,200.

Jen interviewed 150 students for the school paper. She found that 90 of the students volunteer at a
charity. What percent of the students volunteer at the charity?
Answer:
60%
Step-by-step explanation:
90 * 100 = 9000
9000/150 = 60
60%
The percent of the students that volunteer at the charity are 60%.
Total number of students interviewed by Jen = 150
Total number of students who volunteer at charity = 90
Assume that the percent of the students that volunteer at the charity as {x}%. So, we can write -
{x}% of 150 = 90
x/100 x 150 = 90
15x/10 = 90
3x/2 = 90
x = 180/3

The admission fee at a local zoo is $1.50 for children and $4.00 for adults. On a certain day, 2300 people enter the zoo and $7,450.00
is collected. How many children and how many adults attended?
Answer:
700 children and 1600 adults.
Step-by-step explanation:
Given:
The admission fee at a local zoo is $1.50 for children and $4.00 for adults.
On a certain day, 2300 people enter the zoo and $7,450.00 is collected.
Question asked:
How many children and how many adults attended?
Solution:
Let number of children enter the zoo = [tex]x[/tex]
Then number of adults enter the zoo = [tex]2300-x[/tex]
Total collection = $7,450
Collection from children + Collection from adults = 7450
[tex]1.50\times x+4(2300-x)=7450\\ \\[/tex]
[tex]1.5x+9200-4x=7450\\ \\ 2.5x+9200=7450\\ \\[/tex]
Subtracting both sides by 9200
[tex]-2.5x+9200-9200= 7450-9200[/tex]
[tex]-2.5x=-1750[/tex]
Minus is canceled by minus.
[tex]2.5x=1750[/tex]
Dividing both sides 2.5
[tex]x=700[/tex]
Number of children enter the zoo = [tex]x[/tex] = 700
Number of adults enter the zoo = [tex]2300-x[/tex] = 2300 - 700 = 1600
Thus, 700 children and 1600 adults attended the local zoo on that day.
