thousandths - 23 thousandths=how many hundredths and thousandths?
Let us first solve this and get the difference of the given numbers.
=> 56 thousandths = 0.056 (there are 5 hundredths and 6 thousandths)
=> 23 thousandths = 0.023 (there are 2 hundredths and 3 thousandths)
=> 0.056 – 0.023 = 0.033 is the answer
there 3 hundredths and 3 thousandths value left after subtracting the given 2
decimal numbers.</span>
Answer:
5 hours
Step-by-step explanation:
Let s and w represent hours spent traveling south and west, respectively. The problem statement tells us ...
s + w = 8 . . . . . . total trip time
344s + 351w = 2773 . . . . total mileage (using d = s·t)
By Cramer's rule, we can find the value of s as ...
s = (1(2773) -351(8))/(1(344) -351(1)) = -35/-7 = 5
The plane was heading south for 5 hours.

<em>Comment on Cramer's rule</em>
For the equations ...
ax +by = c
dx +ey = f
The solution for x can be found to be ...
x = (bf-ec)/(bd-ea)
Similarly, the solution for y is ...
y = (cd-fa)/(bd-ea)
