The solution of the expression 7/10 - 1/4 is 9/20.
Suppose the fraction is proper (the numerator is smaller than the denominator).
Let it be
Then, we can interpret it as:
= a parts out of b parts of a thing.
WE are given the expression as;
7/10 - 1/4
Now use common denominators;
28/40 - 10/40 = 18/40
= 9/20
The solution of the expression 7/10 - 1/4 is 9/20.

The cost of the dog food without the coupon is $20.
The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %.
It is given that 4 dollars are 20% of the original price of the dog food. Let's have x be the original price of the dog food.
The cost of the dog food without the coupon is calculated as:-
4=x ( 20 )
To get x alone divide both sides by 20 and solve further.
( 4 / 20 )= ( x ( 20) / 20 )
Solve the above equation by cancelling 20 to get the value of x.
4/20=x
Divide 4 by 20 to get the answer and multiply by the value 100 to get the actual cost of the product.
x = 0.2 x 100 = 20
Therefore, the cost of the dog food without the coupon is $20.

2. (3,1) and (3,-1)
Answer:
Perimeter=2L+2w
P=2(x+1)+2(x-3)
P=2x+2+2x-6
P=4x-4
Area=Lxw
A=(x+1)x(x-3)
A=x^2-3x+x-3
A=x^2-2x-3
Step-by-step explanation:

The perimeter of the rectangle is 4x - 4 and the area is x^2 - 2x - 3.
The perimeter of a rectangle is calculated by the formula 2*(Length + Width). Hence, the perimeter for the rectangle in question will be 2*((x + 1) + (x - 3)) = 2*(2x - 2) = 4x - 4.
The area of a rectangle is calculated by the formula Length * Width. Therefore, the area for the rectangle equals (x + 1) * (x - 3) = x^2 - 3x + x - 3 = x^2 - 2x - 3.

The number of stops a bus makes on a certain day is represented by the variable s
Number of stops a bus make cannot be a negative number or irrational number.
WE can consider 0 stops as well.
So it belongs to whole number
Whole numbers best describes the value of the variable
B - y = (0.95 + 1.15)x
C - y = 0.95x + 1.15
D - y = 0.95(x - 1) + 1.15
