C = 8.5x + 6y

Rearrange the equation by making the side with x, be on the Left Hand Side (LHS)

8.5x + 6y = C

Subtract 6y from both sides of the equation

8.5x + 6y - 6y = C - 6y

8.5x = C - 6y

Divide both sides of the equation by 8.5

(8.5x/8.5) = (C - 6y)/8.5

x =  (C - 6y)/8.5

I hope this helped.

Where is (0,19) located? Quadrant I Quadrant II Quadrant III Quadrant IV X-axis Y-axis
12345 [234]
Let P(a, b) be a point on the coordinate plane. Then the following hold:


i) If a>0, b>0 then P is in the I.Quadrant.

ii) If a<0, b>0 then P is in the II.Quadrant.

iii) If a<0, b<0 then P is in the III.Quadrant.

iv) If a>0, b<0 then P is in the IV.Quadrant.

v) If a=0 and b is positive or negative, then P is on the y-axis.

vi) If b=0 and a is positive or negative, then P is on the x-axis.


Since we have: a=0, and 19 positive, then this point is on the y-axis.


Answer: y-axis

The royals softball team played 75 games and won 55 of them. What percent of the games did they lose (round to the nearest hundr
dimaraw [331]
If they won 55 of the games, that means they lost the rest of the 75.  So,
75 - 55 = 20 games lost.  To find the percentage of 20 out of 75, you set up a proportion:

\frac{20}{75}=\frac{x}{100}

where x = the percentage of games lost.  Cross multiply and divide to isolate the x:

\frac{20}{75}=\frac{x}{100}\\75x=2000\\75x/75=2000/75\\x=26.6666667

Rounded to the nearest hundredth, the Royals lost 26.667 % of their games.
