Answer:
8. 11v
9. -19x
10. 6p
11. 16n
12. -4n - 5
13. 15r
14. 9n + 1
Step-by-step explanation:
8. -v + 12v = 11v
9. -8x - 11x = -19x
10. 4p + 2p = 6p
11. 5n + 11n = 16n
12. n + 4 - 9 - 5n = n - 5n + 4 - 9 = -4n - 5
13. 12r + 5 + 3r - 5 = 12r + 3r + 5 - 5 = 15r
14. -5 + 9n + 6 = 9n + 1
Answer:
Yes, is a solution of .
Step-by-step explanation:
Given
To prove that is a solution of the given expression
Take Right hand side :
Substitute the value of
Now , we get
-(n-1)+2+2{-(n-2)+2}+2n-9
=-n+1+2+2(-n+4)+2n-9 ( simplified)
=-n-6+8-2n+2n ( simplified )
=
Hence, LHS=RHS
Therefore, is a solution of given expression
Yes, is a solution of given expression.
Value of 8 in 3,810,200 is 800,000
Value of 8 in 8,911,053 is 8,000,000
800,000 x 10 = 8,000,000
Therefore, the 8 in 3,810,200 is 10 times smaller than the 8 in 8,911,053.
Answer:
