Answer: -2511 (if the periods mean multiplication)
Step-by-step explanation:
I’m not sure whether you’re trying to have the periods be multiplication, but if that’s what they are, this is the answer
5x10-2x8x16x10-1
50-16x160-1
50-2560-1
-2511
Again, I’m not sure if that’s what you mean but I can’t really see what else they would mean since you can’t have a 3 part decimal
The decimal is moved to the front to three spaces
0.003
The most reasonable answer would be 2 meters since two meters equals about 6 feet.
Answer: 8x+12
Distribute the 4. So, 4(2x)+4(3). Then you end up with 8x+12.
I’m not sure what the answer is but I hope someone can help you
