Well you can set it up 26/100 and X/50 and cross multiply to get 100X=1300 and hen divide by 100 and you get 13 then you subtract 50 by 13 to get 37.
Answer:
of a meter in scientific notation.
0.000665 meter in standard notation.
Step by step explanation:
We have been given that Dr. Calvin measured the thickness of a piece of metal to be 0.00064 of a meter. Dr. Amos measured another piece to be 
of a meter thick.
We can see that Dr. Amos has given measurements in scientific notation. Let us convert thickness measured by Dr. Amos from scientific notation to standard notation.
Now let us add both measurements to find the thickness of new metal piece.
Now let us convert thickness of new piece of metal in scientific notation.
Therefore, the thickness of new piece of metal will be of a meter or 0.000665 meter.
395 *25% could also be interpreted as 395/4
395 = 98.75

Answer:
3.4 Hours
Step-by-step explanation:
25 x $7.75 = $193.75
$250 - $193.75 = $21.25
$21.25/$6.25 = 3.4 hours
You must work 3.4 hours at the second job.
North team score is n, south team score is s.
first game equation:
n = (2/3)s
second game equation:
s - 7 = n + 7 - 3
So we have 2 equations and 2 unknowns to solve:
<span>n = (2/3)s
</span><span>s - 7 = n + 7 - 3
</span>lets substitute the first into the second:
s -7 = <span>(2/3)s + 7 - 3
multiply all equation by 3 to eliminate fraction:
3s - 21 = 2s + 21 - 9
s = 21 + 21 - 9
s = 32
that is the souths score of the first game, now substitute in the first equation:
</span><span>n = (2/3)s
</span>n = (2/3)(<span>32)
</span>n = 64/3
n = 21
that is the score of the norths in the first game.
For the second game the norths increased the score by seven that is 21 + 7 = 28
While the souths decreased the score by 7, 32 - 7 = 25
