The answer is a because If 1 inch is 5miles and 5x5 is 25 then a is the answer
Answer:
The first option is not a direct variation
Step-by-step explanation:
When we talk of a direct variation, as one value increases, the other value increases too
Or as one value decreases, the other value decreases
A direct variation is of the form;
y = kx
k = y/x
where k is the coefficient of variation that must be a constant value all through the set of values
The values we are comparing here are the x and y values
So
let us take a look at the options;
The first option is not a direct variation
For the first option, the rate of increase is not constant;
2/6 = 1/3 , 8/12 = 2/3 , 14/18 = 7/9
for the second;
the ratio is 1 to 1
for the third;
3/6 = 1/2 ; 6/12 = 1/2; 9/18 = 1/2
for the fourth;
2/6 = 1/3, 4/12 = 1/3 , 6/18 = 1/3

Answer:
Width: 450 feet
Length: 720 feet
Step-by-step explanation:
So we start with the equation to find the perimeter -
2l + 2w = p
l = length
w = width
p = perimeter
We insert the 2,340 ft as the perimeter -
2l + 2w = 2,340 ft
Now we find another equation for the "length is 270 ft greater than width" -
l = 270 ft + w
Using substitution, we substitute the y in the first equation with 270 ft + w -
2 (270 ft + w) + 2w = 2,340 ft
540 ft + 2w + 2w = 2,340 ft
540 ft + 4w = 2,340 ft
4w = 2,340 ft - 540 ft
4w = 1,800 ft
w = 1,800 ft / 4
w = 450 ft
Now to find the width we substitute the w with 450 ft -
l = 270 ft + w
l = 270 ft + 450 ft
l = 720 ft
Check -
2 * 720 ft + 2 * 450 ft = 2,340 ft
1,440 ft + 900 ft = 2,340 ft
2,340 ft = 2,340 ft (Correct)
