Answer:
14.2 %
Step-by-step explanation:
To find the percent you must make a ratio.
In this case you know the coupon saved you $12, if it saved you $12 then all you have to do is find what percent 12 is of 84, is you divide 12 by 84 and multiply by 100 to give you the percent.
Answer: (or
)
Step-by-step explanation:
The area of a rectangle can be calculated with the following formula:
Where "l" is the lenght and "w" is the width.
In this case we know that the length of a flowerbed is 4 times as long as its width. This can be expressed as:
We know that the width of the flowerbed is:
Therefore, substituting the width into , we get that the length is:
Finally we can substitute the width and the lenght into the formula for calculate the area of a rectangle:

For the given expression v+9/3=8, the value of v is 5.
To find the value of v in the equation v + 9/3 = 8, we can follow these steps:
Simplify the equation.
In this case, we can simplify the equation by dividing 9 by 3, which equals 3.
The equation becomes v + 3 = 8.
Isolate the variable v.
To isolate v, we need to get rid of the 3 on the left side of the equation. We can do this by subtracting 3 from both sides of the equation.
v + 3 - 3 = 8 - 3.
Therefore, in the equation v + 9/3 = 8, the value of v is 5.

b-(-2,-1)
c-(1,-3)
d-(3,7)
Answer:
b - (-2,-1)
Step-by-step explanation:
A function is a mapping in which each element of the domain, or input, is mapped to one element of the range, or output.
In this mapping, the input value -2 is mapped to both 2 and -1; this makes the points (-2, 2) and (-2, -1). If one of these two was removed, the mapping becomes a function.
The only one of these listed in the values given is (-2, -1).
Answer:
(-2,-1)
