Solution:
The given equation is:

A: Taking , x=1
L H S = 9 × 1 + 49 = 9 + 49= 58
R H S : 
L H S ≠ R H S
B: Taking x=3
L H S = 9 × 3 + 49=27 + 49=76
R HS = 
L H S ≠ R H S
C: Taking x=5
L H S = 9 × 5 + 49
= 45 + 49
= 94
R H S:

L H S ≠ R H S
(D)
when , x= 8
L H S
9 × 8 + 49
= 72 + 49
= 121
R HS:

L H S ≠ R H S


Answer: 4y

Step-by-step explanation:
Put it DB and I'll gladly answer!
If you are looking for 185% as a fraction, you need to put your percentage over 100.
185% converted into a fraction is 185/100.
If you are looking for 1.85%, it is 1.85/100
I hope this helps!
