Answer:
The scale used by Sarah is 1 to 43.2 inches ( drawing to actual)
Step-by-step explanation:
Here, we want to know the scale used for the drawing of the Dinosaur by sarah.
The actual height of the Dinosaur is 9 feet, but in her drawing she represented the height by 2.5 inches( 2 1/2 is same as 2.5 inches)
Mathematically, we know that 1 foot is 12 inches;
So the actual height of the Dinosaur is 9 * 12 = 108 inches
So practically, what she has done is to represent a height of 108 inches by 2.5 inches
So the scale factor used will be;
108/2.5 = 43.2
The scale used is 1 to 43.2 or simply 1:43.2 to represent the drawing to the actual

Answer:
y = 
Step-by-step explanation:
Given
2x + 5y = 12
Isolate the term in y by subtracting 2x from both sides
5y = 12 - 2x ( divide both sides by 5 )
y = 
You dont have anything that we can answer to.
These two angles are corresponding angles, so x = 136 degrees
