Answer:

40

Step-by-step explanation:

if you used cross products you'd pair 8 with 100 and n with 20

That written out would be 8(100)=20n

8(100)=800

800=20n

Divide on both sides

800/20=40

Therefore n=40

Morgarella [4.7K]
Let h = Hannah's age.

Hannah is older than her sibling, and their ages are consecutive odd integers. Therefore, h = an odd number and the sibling's age =  h-2.
 
The sum of their ages is 92, therefore
h + (h-2) = 92
2h - 2 = 92

2h = 94
h = 47 years

Answer:
The equation to find Hannah's age is  2h - 2 = 92.
This yields Hannah's age as 47 years.
