I will give brainliest to whoever got the right answer first, so please get it right, help me do number 25, number 26, and number 27, remember and please, READ THE DIRECTIONS.
Answers
25x + 5 = 180
25x = 175
x = 7
Now because there are vertical angles, it is easy to find the value of y.
4y = 9(7) + 5
4y = 63 +5
4y = 68
y = 17
26. 6x - 11 + 2x - 9 = 180 because the angles are supplementary.
8x - 20 = 180
8x = 200
x = 25
Now because there are vertical angles, you can find the value of y.
6(25) - 11 = 20y + 19
150 - 11 = 20y + 19
139 = 20y + 19
120 = 20y
y = 6
27. 9x + 2 + 10x + 7 = 180 because the angles are supplementary.
19x + 9 = 180
19x = 171
x = 9
Again, there are two vertical angles.
10(9) + 7 = 18y + 25
97 = 18y + 25
72 = 18y
y = 4
I really hope this helped you!! :)
25x=180-5
25x=175
x=175/25
x=7
4y+16(7)=180
4y+112=180
4y=180-112
4y=68
y=17
--------------
26.
6x-11+2x-9=180
8x-20=180
8x=180+20
8x=200
x=25
20y+19 +2(25)-9=180
20y=180+9-19-50
20y=120
y=6
--------------
27.
9x+2+10x+7=180
19x=180-9
19x=171
x=9
9(9)+2+18y+25=180
18y=180-81-25-2
18y=72
y=4

you have scored 7,10,8 , and 9 on four quizzes . write and solve an equation to find the score you need on the fifth quiz so that your mean score is 8
Answers
To achieve a mean score of 8 after five quizzes, you would need to score 6 in your fifth quiz, assuming your scores in the first four quizzes were 7, 10, 8, and 9 respectively.
Explanation:Yes, these scores are associated with the subject of mathematics, particularly the branch of math known as statistics. This involves determining how to achieve a desired mean, which in this case is 8, given your previous quiz scores.
The mean score is determined by adding all your quiz scores together and dividing by the total number of quizzes. So for your first four quizzes, the total is 7 + 10 + 8 + 9 = 34. The mean so far is 34 ÷ 4 = 8.5 which is already above our targeted mean of 8.
To achieve a mean of 8 over 5 quizzes, the total of your scores would need to be 8 x 5 = 40. Therefore, the score you would need to get on your fifth quiz would be 40 (the desired total) - 34 (the current total) = 6.

Lillian bought 2.52 pounds of tomatoes and 1.26 pounds of lettuce to make salad for 18 people. If each person got the same amount of salad , how much salad did each person get?
Answers
Answer:
amount of salad by each person = 0.21 pounds
Step-by-step explanation:
Lilian bought 2.52 pounds of tomatoes and 1.26 pounds of lettuce to make salad for 18 people. That means the combined weight in pounds of tomatoes and lettuce is the weight of the salad.
The weight of the salad = 2.52 + 1.26
The weight of the salad = 3.78 pounds
The total weight of the salad is 3.78 pounds . He shared the weight to 18 people and each person collected the same amount.
To find the amount each person got, we divide 3.78 by 18 people.
amount of salad by each person = 3.78/18
amount of salad by each person = 0.21 pounds

Given that 1 meter = 1 x 109 nanometers, what is the diameter of the average cell in the human body, in nanometers? Show your work
The diameter of the average cell in the human body is 1 x 10-5 meters
Answers
We know that 1 meter = 1*10^9 nanometers, meaning that for every one meter is also 1*10^9 nanometers and vice versa. So we can set up the "train tracks"
[
tex] \frac{1*10^9 nanometers}{1 meter} * (1*10^-5 meters) [/tex]
I set it up that way because it cancels out the units "meters" since 1 meter is in the denominator and the other meter is in the numerator.
Then I'll be left with: [tex] \frac{1*10^9 nanometers}{1} * (1*10^-5 ) [/tex]
Now we can solve as is.
[tex] \frac{1*10^9 nanometers}{1} * (1*10^-5) = 10000 nanometers [/tex]

Find y when x=9 if y varies directly as the square of x, and y=100 when x=5.
Answers
Answer:
324
Step-by-step explanation:
Given : y varies directly as the square of x
To Find : Find y when x=9
Solution :
We are given that y varies directly as the square of x
[tex]\Rightarrow y \propto x^2[/tex]
So, [tex]\Rightarrow y= kx^2[/tex] ---1
where k is the constant of proportionality
Now we are also given that y=100 when x=5.
Substitute the values in 1
[tex]100= k(5)^2[/tex]
[tex]100= 25k[/tex]
[tex]\frac{100}{25}=k[/tex]
[tex]4=k[/tex]
So, equation becomes [tex]y= 4x^2[/tex]
Now substitute x= 9
[tex]y= 4(9)^2[/tex]
[tex]y=324[/tex]
Hence The value of y when x is 9 is 324

1,050

Part 3 out of 3
If its total loss was $420 for the week, what was its average daily change?
The restaurant's average daily change was −$
.
Answers
Final answer:
The restaurant gained an additional $450 per day with the special item, lost $1,050 if it had lost $150 per day, and an average daily loss of $60 if the total weekly loss was $420.
Explanation:
To calculate the extra profit per day, we divide the total extra profit by the number of days in a week. $3,150 divided by 7 days gives us $450 extra profit per day.
If the restaurant had lost $150 per day instead, we would multiply the daily loss by the number of days in a week. So, $150 times 7 days equals a total loss of $1,050 for the week.
For the last part, if the total loss for the week was $420, to find the average daily change, we divide this amount by 7. Thus, $420 divided by 7 days equals a daily change of -$60.

Yes, it is a function because each item in the domain matches one item in the ranges.
The domain and range of the relation will be [−4, −1, 1, 2, 2] and [−3, 1, 2, 5, 7], respectively. The relation is a function.
What are domain and range?The domain means all the possible values of x and the range means all the possible values of y.
A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given in the form of a coordinate.
f = {(2, 1), (−4, 5), (1, 7), (2, −3), (−1, 2)}
The domain of the function will be
D = [−4, −1, 1, 2, 2]
And the range of the function will be
R = [−3, 1, 2, 5, 7]
The domain and range of the relation will be [−4, −1, 1, 2, 2] and [−3, 1, 2, 5, 7], respectively.
The relation is a function because the values of the ordinate are different.
