Answer:
Infinitely many solutions.
Step-by-step explanation:
In the equation −2y + 2y + 3 = 3 we see only one variable, and that variable is of the first power. Ordinarily, we'd say that this equation will have 1 solution. However, if we combine like terms, we get 0 + 3 = 3, or 0 = 0, which is true for any and all y values. Infinitely many solutions.
The formula to finding percentages is x% * y = c. So 7% of $4.90 is 0.343.
( 7% is 0.07)
Answer:
Sixth day
Step-by-step explanation:
Keep adding 2 until you get to 13
Refer to the attached image.
Let the width of the border be 'x' inch.
Area of border = Area of rectangle ABCD - Area of rectangle PQRS
Area of rectangle ABCD = 
= 
=
square units.
Area of rectangle PQRS = 
= 
= 117 square units.
So, area of border =
As it is given that the area of border is 48 square units.
So, 


So, the complete equation is
.
Now, we will find 'x' in the equation
,


(x-1) (x+12)=0
So, x = 1 or x = -12
Width can'not be negative.
So, x = 1 .
Therefore, the width of the border can'not be 2.5 inch.
Therefore, the width of the border is 1 inch.
