Answer:
Step-by-step explanation:
Let age of each twin be x
let age of sister be s
So we can write:
x + 4 = s
The product of the 3 siblings ages is 3482 more than sum. We can write:
This can be simplified as:
We replace s with "x + 4" and solve:
<u>Note:</u> To solve this cubic, we used technology
Thus, we can say the twins are 14 years old
24.5 should be the missing number. 13.5 (13 1/2) + 5.5 is 19. 19 + 5.5 is *24.5*. 24.5 + 5.5 is 30. Basically, you go up by 5.5 every number.
