Answer:
b
Step-by-step explanation:
significant figures means counting the digits that either come before a trail of zeros (45.0000 has 7 significant figures) or come after a trail of leading zeros (00.31 has two significant figures, because the zeros before the decimal point have no other digit in front of them and do not count) 1005.0 would have 6 significant figures
No
if you solve the equation
2x - 3 = 9
2x = 9 + 3
2x = 12
x =12/2
x =6
answer is B (second choice)
