This equation shows how the total amount of paper Shelby's office has recycled depends on the number of weeks since they started the new recycling plan. p = w + 14. The variable w represents the number of weeks the office has been on the new recycling plan, and the variable p represents the total kilograms of paper recycled. How many weeks will it take Shelby's office to recycle a total of 16 kilograms of paper?
solve the proportion 2x+1/6 = 7/9
Answer: x=11/36
Step-by-step explanation:
Step One-Subtract 1/6 from both sides.
2x+1/6-1/6=7/9-1/6
2x=11/18
Step Two-Divide both sides by 2.
2x/2=11/18/2
x=11/36.

Answer:
you need to find out how many miles per hour irst then see how many itll be in 24 hours
Step-by-step explanation:
Answer:
D = 6.2t, where t is in hours
Now, solve for 24 hours for t.
D = 6.2(24) = 148.8 miles in 24 hours.
Step-by-step explanation:
First, find out how far the butterfly can fly in 1 hour.
93 miles / 15 hours = 6.2 miles per hour
Let D = the distance in miles the butterfly can fly in t hours.
Your equation will be
D = 6.2t, where t is in hours.

Calculator What is mZCDJ?
Answer: 34°
Step-by-step explanation:
1. 4x+3x-8=90, add 8 to both sides, so -8 cancels on the left side and 90 becomes 98. Then combine 4x and 3x, you get 7x=98, finally divide both sides by 7, the 7 on the left side cancels and 98 becomes 14. So X=14.
2. Now input 14 into 3x-8. So 3(14)-8=34°, check your work by input 14 in 4x and then adding them both together, they should equal 90. So 4(14)=56 and 34+56=90 so 34° is correct.

quadrilaterals ABCD and WXYZ are similar.
What is the value of k in meters?
1.2 m
2 m
4.6 m
15.3 m
Answer:
The value of k = 4.6 m
Step-by-step explanation:
As you see in the question diagram, quadrilateral WXYZ is the same shape as quadrilateral ABCD, but it's two times larger.
The reason is that one of the lengths BC of the quadrilateral ABCD is 4.2 m, and its corresponding length XY of the quadrilateral WXYZ is twice times larger.
i.e. 4.2 × 2 = 8.4 m
As the quadrilaterals are similar. It means if the length CD of the quadrilateral ABCD is 2.3 m, its corresponding length YZ of the quadrilateral WXYZ must be twice times larger.
i.e. 2.3 × 2 = 4.6 m
Therefore, the value of k = 4.6 m

A boat traveled 126 miles downstream and back. The trip downstream took 6 hours. The trip back took 42 hours. What is the speed of the boat in still water? What is the speed of the current?
Answer:
The answer is
Speed of the boat in still water= 12mph
Speed of current= 9mph
Step-by-step explanation:
let x= speed of the boat in still water
let y= speed of current
DATA WE HAVE
with current
rate- x+y
time- 6 hours
distance- 126 miles
rate= 126/6= 21
against current
rate- x-y
time- 42hr
distance- 126 miles
126/42= 3
Now, we add these two equations vertically.
x-y=3
+
x+y=21
2x = 24
Now we divide each side by 2
2x/2 24/2
x= 12
The speed of the boat in still water is 12mph
NOW WE HAVE HALF OF THE ANSWER
if x+y= 21
then
12+y=21
subtract 12 from both sides
y=9
The speed of the current is 9mph
Checking)
12+9=?21
21=21
12-9=?3
3=3
I hope this helped! If you have any questions, dm me on insta celinesaydawi
The speed of the boat in still water is 6 mph, and the speed of the current is 4.5 mph.
Given that a boat traveled 126 miles downstream and back, and the trip downstream took 6 hours, while the trip back took 42 hours, to determine what is the speed of the boat in still water and what is the speed of the current, the following calculations must be performed:
(126/2) / 6 = 10.5 mph downstream (126/2) / 42 = 1.5 mph against current (10.5 - 1.5) / 2 = 4.5 mph (current speed) 10.5 - 4.5 = 6 1.5 + 4.5 = 6 6 mph = speed of the boat in still water
Therefore, the speed of the boat in still water is 6 mph, and the speed of the current is 4.5 mph.

examine the graph below. select the solutions to the graph from the following points. select three that apply.
Answer:
Options (1), (2), (3)
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Given line on the graph is passing through two points (-3, 0) and (0, 1).
Slope of this line will be,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
= [tex]\frac{1-0}{0+3}[/tex]
= [tex]\frac{1}{3}[/tex]
y-intercept of the line 'b' = 1
Equation of the line will be,
y = [tex]\frac{1}{3}x+1[/tex]
If the points given in the options satisfy the equation, they will be the solution of the line.
Option (1),
For (3, 2),
2 = [tex]\frac{3}{3}+1[/tex]
2 = 2
True.
(3, 2) is the solution.
Option (2)
For (21, 8),
8 = [tex]\frac{21}{3}+1[/tex]
8 = 8
True.
(21, 8) is the solution.
Option(3)
For (-15, -4),
-4 = [tex]\frac{-15}{3}+1[/tex]
-4 = -4
True.
(-15, -4) is the solution.
Option (4)
For (12, 9)
9 = [tex]\frac{12}{3}+1[/tex]
9 = 5
False
(12, 9) is not the solution.
Option (5)
For (-6, 1)
1 = [tex]\frac{-6}{3}+1[/tex]
1 = -1
False
(-6, 1) is not the solution.
Therefore, Options (1), (2), (3) are the solutions.

Which of the following (x,y) pairs is the solution to the system of equations –3x + y = –8 and x + 2y = 12 ?
Answer:
The answer is (4,4)
Step-by-step explanation:
I had this same problem and got it right so can you give me 5 stars:)
The solution of the system of equations –3x + y = –8 and x + 2y = 12 will be (4,4).
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given,
–3x + y = –8 and x + 2y = 12
Multiplying by 2 to equation first
-6x + 2y = -16 and x + 2y = 12
Substracted equation second to first
7x = 28
x = 4
By substituting
y = 4
Hence "The solution of the system of equations –3x + y = –8 and x + 2y = 12 will be (4,4)".

If you are rolling two dice (numbered 1-6), what is the probability that the first die shows a 4 and the second die shows a 2?
Answer:
Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on.
1 out of six for both numbers
you have six numbers and 1-6 therefor its a 1 outta 6 chance
Tickets for a concert cost eight dollars for the main floor and six dollars for the balcony If 1125 tickets were sold and the tickets sales total 8050 how many tickets of each kind were sold
Answer:
650 tickets for the main floor and 475 tickets for the balcony were sold.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=1125 (1)
8x+6y=8050 (2), where:
x is the number of tickets for the main floor
y is the number of tickets for the balcony
First, you can solve for x in (1):
x=1125-y (3)
Second, you can replace (3) in (2):
8(1125-y)+6y=8050
9000-8y+6y=8050
9000-2y=8050
9000-8050=2y
950=2y
y=950/2
y=475
Third, you can replace the value of y in (3) to find x:
x=1125-y
x=1125-475
x=650
According to this, the answer is that 650 tickets for the main floor and 475 tickets for the balcony were sold.
