Answer:
c
Step-by-step explanation:
only 2 students were asked the question, 2 students don't represent the whole population
Answer: w+1.3 = 2.7
Reason:
The smaller pieces (w and 1.3) combine to form the larger piece (2.7)
To find w, subtract 1.3 from both sides to get 1.4
1.4+1.3 = 2.7
Answer: True
Step-by-step explanation:
We try to keep the number greater than 1 and lower than 10, so between 1, and 9.
For example: 3545346 would be 3.5x10^6
you can see 3.5 is between 1 and 9
