For this case we have:
, we must run the decimal point 20 spaces to the left.

, we must run the decimal point 12 spaces to the left.

Thus, it is observed that the mass of a small virus is smaller!
We subtract and obtain:

ANswer:
The mass of a small virus is less!
The first graph shows the correct location of the points.
Answer:
(2,
)
Step-by-step explanation:
Given the 2 equations
2x + 3y = 17 → (1)
3y = 15 - x → (2)
Substitute 3y = 15 - x into (1)
2x + 15 - x = 17, that is
x + 15 = 17 ( subtract 15 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting in (1)
2(2) + 3y = 17
4 + 3y = 17 ( subtract 4 from both sides )
3y = 13 ( divide both sides by 3 )
y = 
Solution is (2,
