L 6 w 8 is the right answer to the question
Answer:
A) y=5x+9 B) -5x+y=9
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1)=5(x-(-2))
y+1=5(x+2)
y=5x+10-1
y=5x+9
y-5x=9
-5x+y=9
Answer:
n+18=7(n-3)
Step-by-step explanation:
Lets replace "A number" with the variable n because we do not know its value!
1) Rewrite the problem as an equation
n+18=7(n-3)
<u>If we want to solve the equation, do the following:</u>
1) Distribute 7 to n and -3:
n+18=7n-21
2) Add 21 to both sides:
n+39=7n
3) Subtract n from both sides:
39=6n
4) Divide both sides by 6:
n=6.5
When there is one soda, there is 25 cents, and when there are 3 sodas, there are 75 cents included in the total. So, it's safe to assume that the soda has a minimum of 25 cents each.Then, there are the same amount of donuts in both parts. So, the donuts will take up the same amount of money in both. If you can find how much those donuts are worth, you can find how much the sodas are worth, plus the 25 cents, for each.
If the donuts are worth $1 each, then take away $2 from each total.
You'll get 6.75 for the first, and 2.25 for the second.
From reasoning, you can get that each soda is equal to $2.25 and each donut is equal to $1.
There are different ways to do this, but the way I did it is simply the way my brain works.
Answer:
The length of the yard is 60 feet while the width is 30 feet.
Step-by-step explanation:
If the length of Mr. Timmon's backyard is double the width, then the dimensions are related by the following expression:
length = 2*width
We also know the perimetter, since he has the exact length of fence to surround his whole yard, which is 180 feet. The perimeter of a rectangle is given by:
perimeter = 2*length + 2*width
Therefore,
180 = 2*length + 2*width
With the length being double the width, we have:
180 = 2*(2*width) + 2*width
180 = 4*width + 2*width
6*width = 180
width = 180/6 = 30
length = 2*width = 2*30 = 60
The length of the yard is 60 feet while the width is 30 feet.
