Answer:
4 dogs :]
Step-by-step explanation:

Answer:
29
Step-by-step explanation:
In this question we are trying to calculate the cost of exact amount of fabric used given the cost per area of the fabric.
To answer this question mathematically, we need to know the area of the bulletin board. To do this , we employ a mathematical approach. We know that the bulletin board is circular in shape from the question and thus we calculate the area of this shape.
Mathematically, the area of the circular bulletin board is pi * r^2 where r refers to the radius. From the question, we can identify that this radius is 2.5 feet. let’s insert this into the equation we have.
mathematically A = 2.5^2 * pi = 19.63 sq. feet
The cost of the fabric per square feet is 1.48.
now the cost for this area that we have will be 1.48 * 19.63 = 29.0524
This is nearest to 29
Hello!
-2x + y = 1
-4x + y = -1
You can subtract these equations from each other to eliminate y
2x = 2
Divide both sides by 2
x = 1
Put this into one of the original equations
-2(1) + y = 1
Combine like terms
-2 + y = 1
Add 2 to both sides
y = 3
The answer is D) (1, 3)
Hope this helps!
