Answer:
b
Step-by-step explanation:
2.6 • 10^10 = 26,000,000,000
4.94 • 10^13 = 49,400,000,000,000
49,400,000,000,000/26,000,000,000= 1900
And adult had 1900 times more cells than a newborn. Or if you want to put it in scientific notation it would be 1.9 • 10^3
Lst question: x = 5, y = 7
2nd question: x = -1, y = 5
3rd question: x = 98, y = 80
