Answer:
Step-by-step explanation:
We know that for principal amount P , time period T and rate of interest 
, simple interest is given by 
.
Here ,
To find : simple interest rate i.e.,
On putting values of 
in formula , we get

=
Consider the number of the adult tickets is x
X+2x=276
3x=276
X=92
So the student tickets is =184
Answer:
The correct answer is x= - 3
Step-by-step explanation:
Equation is :( x + 2 )² + ( y - 1 )² = r²( - 4 + 2 )² + ( 1 - 1 )² = r²4 = r², than we will plug in to a formula:( x + 2 )² + ( y - 1 )² = 4x² + 4 x + 4 + y² - 2 y +1 = 4x² + y² + 4 x - 2 y + 1 = 0
the answer is : <span>x2 + y2 + 4x − 2y + 1 = 0 </span>
