Using the equation for the area of a rectangle, the original width of the pen is determined by:
9.5 (W + 5.7) = 77.9
The area of a rectangle of length l and width w is given by:
[tex]A = lw[/tex]
In this problem:
Increases the width by 5.7 yards, hence [tex]w = w + 5.7[/tex], in which w is the original width.The length remains at 9.5 yards, hence [tex]l = 9.5[/tex].The area is of 77.9 square yards, hence [tex]A = 77.9[/tex]Then:
[tex]A = lw[/tex]
[tex]9.5(w + 5.7) = 77.9[/tex]

Where is the blue dot on the number line ?
Answer:
-12
Step-by-step explanation:
Since the segments go by 3, with each segment to the left I subtracted 3, so it was 0, -3, -6, -9, and then the blue dot stood on the segment -12, and that's your answer.
Tell me if I'm wrong :)
Answer: -12
Step-by-step explanation: The number line is going by 3's, so since the blue dot is 4 dashes away from 0 with the first dash being -3, that can only mean that the answer is -12.
Hope this helped and let me know if its correct!

O A. y = 5x
OB. y = 5x + 10
O C. y = x
OD. y = 5x - 1
Answer:
y =5x
Step-by-step explanation:
[tex]y_{1}-y_{2} = m(x_{1} - x_{2} )[/tex]
(5 - 0) = m(1 - 0)
5 = m(1)
5 = m
[tex]y_{1}-y_{2} = m(x_{1} - x_{2} )[/tex]
y - 5 = 5(x - 1)
y - 5 = 5x - 5
y = 5x -5 + 5
y = 5x

Step-by-step explanation:
A canoe travels 8 miles per hour downstream and 2 miles per hour upstream.
Let x represent the canoe's speed with no water current (still water) and y
represent the speed of the water current, in miles per hour. Then the situation
can be represented by this system of equations:
X+ y = 8
x - y = 2
Choose the two correct options.
A. The speed of the canoe in still water is 3 miles per hour.
B. The speed of the water current is 5 miles per hour.
C. The speed of the water current is 3 miles per hour.
D. The speed of the canoe in still water is 5 miles per hour.
Answer:
D
Step-by-step explanation:
I know this is super late and you probably don't need this, but for anyone who needs it, here is the answer!
Answer:
D and C
Step-by-step explanation:
We are doing the elimination method. We are subtracting so we can eliminate the x variable
x + y = 8
- (x - y = 2)
---------------------
0x + 2y = 6
(0x is there just to show that x is eliminated but the equation is now just 2y = 6)
now solve for y (divide 2 on both sides)
y = 3
Now we can use Y to find x. Use any equation (either x + y = 8 or x - y = 2) and then plug in the y value.
x - 3 = 2.
Add 3 on both sides and you get
x = 5
Now! From the question we see that x is canoe speed and y is water current speed. And since x is 5 and y is 3, the answer is D and C since the water current is 3 and canoe speed is 5. Hope this helps!!

If a crate of 250 apples costs $95, what is the unit cost
The unit cost of an apple in a crate of 250 apples is $2.63.
Given the following data:
Total number of apples in a crate = 250 applesCost of a crate of apple = $95To determine the unit cost of an apple:
In this exercise, you're required to calculate the cost of one apple in a crate, knowing that there are 250 apples in total at a cost of $95.
Thus, we would divide the total number of apples by the total cost of all the apples as follows:
[tex]Unit\;cost = \frac{Total\;apples}{Total\;cost}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Unit\;cost = \frac{250}{95}[/tex]
Unit cost = $2.63

A bedroom is in the shape of a square. The length of the room is 6p7q. What is the area of the bedroom in terms of p and q?
Answer:
(6p7q)²
Step-by-step explanation:
you have to square the length to find the area of a square
The area of the bedroom would be (6p7q)² square units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
A bedroom is in the shape of a square. The length of the room is 6p7q.
According to the given question, we can write the dimension as:
The width of the room = 6p7q units
The length of the room = 6p7q units
The area of the room = width of the room × length of the room
The area of the room = 6p7q × 6p7q
Apply the multiplication operation,
The area of the room = (6p7q)² square units
Therefore, the area of the room is (6p7q)² square units.

How to express a mixed number as a percent
Answer:
Make it an improper fraction and multiply by 100
Answer:
Well a percent means out of a hundred
And a mixed number is
x e/y (example)
Now we know the whole number is already 1 and above so we know that’s already a 100%
Now we just need to add the other fraction to the 100%.
Thats it!
OR you can do convert the mixed number into an improper fraction.
From there make a proportion of the improper fraction equaling x/100
Now solve the proportion by cross multiplying.
Solve for x

y = 2x + 2
Step-by-step explanation:
for each rise of 4 in y
there is a run of 2 in x
m = rise/run
m = 4/2
m = 2
when x = 0, y = 2
