Question

9. If the expression 5 + (2 + 4) = (Z+Y) + 4 follows Associative property, then among
the following Y and Z values
Respectively
1) Y=2, Z=5 2) Y=5, Z=10 3) Y=2, Z=10 4) Y=5, Z=2​

Answer 1

Answer:

1. y=2,z=5

5+(2+4)=(z+y)+4

5+(2+4)=(5+2)+4

5+6=7+4

11=11

2. y=5z=10

5+(2+4)=(z+y)+4

5+(2+4)=(10+5)+4

5+6=15+4

11=19

3. y=2 z=10

5+(2+4)=(z+y)+4

5+(2+4)=(10+2)+4

5+6=12+4

11=16

4. y=5 z=2

5+(2+4)=(z+y)+4

5+(2+4)=(2+5)+4

5+6=7+4

11=11

1 and 4 are associative property
