Answer:
2. x = 47
3. x = 2 
Step-by-step explanation:
These problems involve proportions, or equivalent ratios.  You can solve for 'x' in each by using cross-multiplication and division. 
2.  28(7) = 4(x + 2) 
Distribute = 196 = 4x + 8
Subtract 8 from both sides: 196 - 8 = 4x + 8 - 8 or 188 = 4x 
Solve for x:  x = 47
3.  2(2x + 7) = 11(3x - 4) 
Distribute: 4x + 14 = 33x - 44 
Add 44 to both sides: 4x + 14 + 44 = 33x - 44 + 44 or 4x + 58 = 33x 
Subtract 4x from both sides: 4x + 58 - 4x = 33x - 4x or 58 = 29x 
Solve for x: x = 2 
 
        
             
        
        
        
Let x represent the height of the model.
We have been given that a construction company built a scale model of a building. The model was built using a scale of 3 inches = 32 feet. We are asked to find the height of the model, if  the building is expected to be 200 feet tall.
We will use proportions to solve our given problem as:

Upon substituting our given values, we will get:




Therefore, the model will be 18.75 inches tall.
