Answer:
so the distance between the police and the library is 2x-3 where x is the distance between the police and fire and distance between the library and fire is 5 so
2x-3=5
2x=8
x=4
so C
Hope This Helps!!!
Answer:
x>4
Step-by-step explanation:
Answer:
(5 , 7)
Step-by-step explanation:
let a = the number of adult tickets
let c = the number of children tickets
then we have to solve the following system
a + c = 12
14.5a + 9c = 135.5
we proceed by Substitution:
c = 12 - a
14.5a + 9c = 135.5
After some calculations we find
a=5 and c=7
Answer:
A) Rational
B) Irrational
C) Rational
D) Irrational
Step-by-step explanation:
Irrational numbers cannot be expressed as a ratio of two number, whereas rational numbers can be. 81 can be expressed as 9*9 whereas, 89 cannot be expressed as ratio of two numbers.
Answer: x = 2 ; -11 .

Explanation:
_____________________________________________
Given the equation:
_____________________________________________
x² + 9x −<span> 22 = 0 ; Solve for: "x" ;
_____________________________________________
Let us factor the "left-hand side" of the equation:
_____________________________________________
"x</span>² + 9x −<span> 22" ;
_____________________________________________
What are the factors of "-22"" that add up to "positive 9" ?
_____________________________________________
Let us list the factors of "-22" :
____________________________________________
-2, 11; </span>→ -2 + 11 = 9 ;<span>
-11, 2; </span>→ -11 + 2 = -9 ;<span>
____________________________________________
So we have: "-2" and "11" ;
____________________________________________
So; </span> "x² + 9x − 22" ; factors into " (x−2)(x + 11)" ;
____________________________________________
We have: (x−2)(x + 11) = 0 ;
So: x − 2 = 0 ;
Add "2" to each side of the equation;
x − 2 + 2 = 0 + 2 ;
x = 2 ;
___________________________________
x + 11 = 0 ;
Subtract "11" from each side of the equation;
x + 11 − 11 = 0 − 11 ;
x = -11 ;

Answer: x = 2 ; -11 .
