$recall\ that\implies \cfrac{\frac{a}{b}}{\frac{c}{{{ d}}}}\implies \cfrac{a}{b}\cdot \cfrac{{{ d}}}{c}\qquad thus
\\ \quad \\

\cfrac{\frac{3g}{4}}{\frac{2m}{3}}\implies \cfrac{3g}{4}\cdot \cfrac{3}{2m}\implies \cfrac{\square ?}{\square ?}
\\-------------\\
\cfrac{\frac{5g}{8}}{\frac{1m}{2}}\implies \cfrac{5g}{8}\cdot \cfrac{2}{1m}\implies \cfrac{\square ?}{\square ?}$

so... you tells us, which filling rate is the bigger and thus faster one?

Ax-by/c =d solve for x

wolverine [178]

Answer: x = (cd + by) / a

Working out:

(ax - by) / c = d

1)Multiply by c on both sides to get:
ax - by = cd

2) Add by on both sides to get:
ax = cd + by

3) divide by a on both sides to get:
x = (cd + by) / a

Solve the system using elimination.

Molodets [167]

Answer:

(-1, 3)

Step-by-step explanation:

x - 5y = -16 [Equation 1]

-x + 3y = 10 [Equation 2]

<u>Adding both equations</u>

x - x - 5y + 3y = -16 + 10
-2y = -6
y = 3

x - 5(3) = -16
x - 15 = -16
x = -1

<u>Solution</u> : (-1, 3)
