Answer:
11%
Step-by-step explanation:
We need to fill the missing cells of the table first and are interested in first row for under age 15
1. 152- 65= 87 for the top left cell
2. 165- (87+60)= 18 for car column on same row
now we have number 18 and the total of the first row is 165:
So the first choice- 11% is the answer
 
        
             
        
        
        
Answer:
x = 5; y = 138, z= 42
Step-by-step explanation:
4x- 17 = 3 [ opposite sides of a parallelogram are equal]
4x = 3+ 17 = 20; X= 20/4 = 5
138 + Z = 180( angle on a straight line)
Z is an alternate angles to the remaining angle off 138 forming the straight line.
z= 180-138 = 42 degrees
Y = 138 [ opposite angles of a regular quadilareral been equal]
