Answer:
30 square feet
Step-by-step explanation:
to find the area, simply multiply 15 and 14.
now the answer is 210 inches.
Now to convert to scale, divide 7 into 210.
The area of the ballroom is 30 feet.
 
        
             
        
        
        
Multiply2 * x/15 to 2x/15
multiply both sides by 30 which is the LCM of 10, 5, 3, and 15
expand it
simplify 18 - 15x - 12x - 6 + 10x to 12 - 17x
add 17x to both sides
add 4x + 17x to = 21x
divide both sides by 21
simplify 12/21 to 4/7
now simplify
Answer: x = 4/7.
        
             
        
        
        
Answer:

Step-by-step explanation:
 
        
             
        
        
        
1) 462/11= 42 
   42x7=294
2) 9.38/7= $1.34
3) 6/11= 0.54545454545455
4) 1/4= 0.25
    2/9= 0.22222222222
    3/10= 0.30
    2/1= 2.00
    1/5= 0.20 
    least to greatest- 1/5, 2/9, 1/4, 3/10, 2/1
5) 9/15= 0.6 > 60%
     to turn into a percent, move 2 decimal places!
6) 10/4= 2.5
     2.5x18= 45 
7) 2/3= 0.66666666666
    0.66666666666x7= 4.66666666667
