Answer:
5 significant figures
Step-by-step explanation:
looking at the last two digit of the numbers, it multiplication gives, 4*5=20
we already have four significant figures ,
so, 2 would be the fifth since 0 is not going to be counted
28 + 6 = 34 and 34 - 3 = 31!!!!!!!
Answer:
4) d = 1
5) w = 11
6) q = 120
Step-by-step explanation:
<em>4)</em> 
Adding 5 on both the sides ,


Dividing both the sides by 9 ,


<em>5)</em> 
Substracting 6 from both the sides ,


Dividing both the sides by -3 ,


<em>6)</em> 
Adding 19 on both the sides ,


Multiplying both the sides by 8 ,
