Answer:
The width of the scale model is 33 inches.
Step-by-step explanation:
This question is solved making a relation with the scale model.
In the scale, 3 inches are worth 11 real feet.
The actual width of the building is 121 feet, so we find it's scale by a rule of three.
3 inches - 11 feet
x inches - 121 feet
Simplifying by 3, both sides
The width of the scale model is 33 inches.

Answer: The three consecutive odd integers are: -15, -13, and -11 .
_______________________________________________________
Explanation:
_____________________________________________
x + (x + 2) + (x + 4) = -39 ;
_____________________________________________
in which "x" is one of the integers,
"(x + 2)" is the next consecutive odd integer;
"(x + 4)" is the third consecutive odd integer.
__________________________________________
By solving for "x", we can solve for each of three (3) consecutive odd integers.
________________________________________________________
x + (x + 2) + (x + 4) = -39 ;
_________________________________________________________
1x + 1x + 2 + 1x+ 4 = -39 ;
_____________________________________________________
3x + 6 = -39 ;
______________________________________________
Subtract "6" from EACH side of the equation:
______________________________________________
3x + 6 − 6 = -39 <span>− 6 ;
____________________________________________________
to get: 3x = -45 ;
____________________________________________________
Divide EACH side of the equation by "3" ;
____________________________________________________
3x / 3 = -45 / 3 ;
_____________________________________________________
to get: x = -15 ;
______________________________________________________
x + 2 = -15 + 2 = -13 ;
_______________________________________________________
x + 4 = -15 + 4 = -11 .
___________________________________________________
Are: -15, -13, and -11 ; Consecutive odd integers? YES!
___________________________________________________
Does: -15 + (-13) + (-11) =? = -39 ??
_____________________________________________________
-15 </span>− 13 <span>− 11 = ? 39 ?? YES!
____________________________________________________
Answer: The three consecutive odd integers are: -15, -13, and -11.
