X + 44 is correct
X = AN UNKNOWN
Answer:
Step 1: Flip the equation.
−x−2=y
Step 2: Add 2 to both sides.
−x−2+2=y+2
−x=y+2
Step 3: Divide both sides by -1.
−x
−1
=
y+2
−1
x=−y−2

The ratio of the model's height to actual height of tower is 1:725
Step-by-step explanation:
Given
Actual height of Sears Tower =
= 1450 feet
Height of Model =
= 24 inches
We can divide the actual height by the model's height to find the scale
Let z be the ratio of the height of the model to the actual height

The ratio should be in same unit.
We know that
1 ft = 12 inches
Then

Hence,
The ratio of the model's height to actual height of tower is 1:725
