Answer
1. 6x + 18 = 48
2. x/2 + 6 = 14
Step-by-step explanation:
1. Its 18 plus meaning + then 6$ per hour and we dont know how many hours so you put the X next to it!
2. First he sold half so but we dont know the starting number so we put x/2 then we have to add 6 and we get 16

As a part of your project studying tipping behavior, you ask people the question, How much should you tip a grocery bagger for carrying five bags to your car? The Grocery Bagger Surveys tab of this spreadsheet gives the responses to this question from 10 independent surveys, each with 50 respondents. The respondents were asked to round to the nearest quarter, since few people tip with pennies, nickels, and dimes. In the spreadsheet, you can calculate the mean, or average, of data using the Average function: Select the cell in which you want the mean to appear. Type =AVERAGE( in the formula bar. Select all the cells containing the values for which you want to find the average, and then press Enter. The average of the values in the cells will be calculated and displayed in the cell in which you entered the formula. Question 1 What is the sample mean of the responses in survey 1?
Answer:
The sample mean for survey 1 is $1.69.

Find the equation that passes through points A and B
Answer:
Step-by-step explanation:
A(1,7); B(-3,-1); slope m =(-1-7)/-3-1) = -8/-4 = 2
Equation of a line AB is
((y-y1) = m(x-x1)
y - 7 = 2(x-1)
y - 7 = 2x-2
y = 2x + 5
Answer:
y = 2x +5
Step-by-step explanation:
Equation of a line
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The image provides two points A(1,7) and B(-3,-1), thus the slope is:
[tex]\displaystyle m=\frac{-1-7}{-3-1}[/tex]
[tex]\displaystyle m=\frac{-8}{-4}[/tex]
m = 2
Now we apply the point-slope form taking the point (1,7):
y - 7 = 2 ( x - 1 )
Operating:
y - 7 = 2x - 2
Adding 7:
y = 2x +5

Can someone help me with this ??
I need help with the range
Answer:
[-9, 0]
Step-by-step explanation:
The range is the y values that the equation/line covers.
The line's lowest point is -9 and the line's highest point is 0. The values are defined (no open circle at the highest point) so we use brackets.
The height of the Statue of Liberty is 305 feet. Nicole, who is standing next to the statue, casts a 6-foot shadow. She is 5 feet tall. How long should the shadow of the statue be?
Answer:
Create a proportion.
[tex]\frac{5}{6} = \frac{305}{x}\\[/tex]
This proportion is saying,
"If 5 corresponds to 6, then 305 corresponds to what?"
Cross multiply.
5x = 305(6)
5x = 1830
x = 1830 / 5
x = 366
So, the shadow of the statue should be 366 feet.
What number needs to be in the blank for this system to have an infinite number of solutions?
y = -3x + 1
6x + 2y = ?
Answer:
? = 2
Step-by-step explanation:
Given:
y = -3x + 1
6x + 2y = ?
Slope-intercept form:
6x + 2y = a
y = a/2 - 3x
y = -3x + a/2
or y = -3x + 1/2a
Go back to given equations:
y = -3x + 1
y = -3x + 1/2a
y = y
-3x + 1 = -3x + 1/2a
1 = 1/2a
a = 2

x + 10y = 30
to
y = mx + b form
Answer:
y = - [tex]\frac{1}{10}[/tex] x + 3
Step-by-step explanation:
Given
x + 10y = 30 ( subtract x from both sides )
10y = - x + 30 ( divide all terms by 10 )
y = - [tex]\frac{1}{10}[/tex] x + 3

Divide $63 among three men in the ratio 1/2 : 1/4 : 1/8. How much will each get?
Answer:
1st: $36
2nd: $18
3rd:$9
Step-by-step explanation:
The first man gets 4
The second gets 2
The third gets 1
4 + 2 + 1 = 7
63/7 = 9
Each part equals $9
9*4 = 36
9 * 2 = 18
9 * 1 = 9
Check:
36 + 18 + 9 =
63
What’s the greatest common factor of 36 , 48, an 80?
Answer: 4
Step-by-step explanation:
36,48,80
80 = 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

Amara needs 45kilograms of meat to feed her 2pet dragons each day. Each pet dragon eats the same amount of meat.
How many kilograms of meat does Amara need to feed 4 pet dragons each day?
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
She needs 45 kg meat for 2 pets
each pet feed the same, i.e,
one pet eats = 45/2 = 22.5 kg meat
then 4 pet dragons will eat = [tex] 22.5kg \times 4 = 90 kg [/tex] meat.
Hence, Amara needs 90 kilograms of meat to feed 4 pet dragons each day.
Draw the dilation of ABCD using center D and scale factor 1/3. Label the dilation EFGH
Answer:
Please find attached, the required drawing of quadrilateral ABCD and the dilation of quadrilateral ABCD scaled down by a scale factor of 1/3
Step-by-step explanation:
The coordinates of the quadrilateral ABCD are;
A(0, 6), B(6, 6), C(9, 0), D(0, 0)
From the dilation by a scale factor of 1/3, using D as the center of dilation, we have from the attached drawing, the following coordinates of the quadrilateral EFGH as E(0, 2), F(2, 2), G(3, 0) H(0, 0) which is the quadrilateral ABCD scaled down by 1/3
