Answer:
D) 3 X 10⁷
Step-by-step explanation:
<u>Estimated days:</u>
- Jan 2000 to June 2001 = 1.5 years = 365*1.5 days ≈ 548 days
- 1 day = 24 hours = 24*60 minutes = 24*60*60 seconds =
- 548 days = 548 * 86400 seconds =
Best estimate is D) 3 X 10⁷
Answer is C.
x+(x+2)+(x+4)=105
Simplifies to 3x+6=105
Solve for x. x=33, x+2=35. x+4=37
33+35+37= 105
X/y = 1
Your answer is one.
