$\bf 2\frac{1}{2}\left( 8x-\cfrac{4}{5} \right)=-62\implies \cfrac{5}{2}\left( 8x-\cfrac{4}{5} \right)=-62\implies \stackrel{\textit{distributing}}{\cfrac{5\cdot 8}{2}x-\cfrac{5\cdot 4}{2\cdot 5}}=-62 \\\\\\ 20x-2=-62\implies 20x=-60\implies x=\cfrac{-60}{20}\implies x=-3$

Which expression gives the distance between the points

Alla [95]

Answer:

Step-by-step explanation:

The formula for finding the distance between 2 points (x1, y1) and (x2, y2) is

d = √[(x2 - x1)² + (y2 - y1)²]

Here (x2, y2) = (2, 3) and (x1, y1) = (4, -3)

Plugging them gives us

d = √[(2 - 4)² + (3 - (-3))²]

d = √[(2 - 4)² + (3 + 3)²]

A jar contains 8 4/9 pounds of jam. If Sam eats 3 2/5 pounds of the jam, how many pounds of jam remains in the jar?

zepelin [54]

$\bf 8\frac{4}{9}\implies \cfrac{8\cdot 9+4}{9}\implies \cfrac{76}{9}
\\\\\\
3\frac{2}{5}\implies \cfrac{3\cdot 5+2}{5}\implies \cfrac{17}{5}\\\\
-------------------------------\\\\
\cfrac{76}{9}-\cfrac{17}{5}\impliedby \textit{let's use an LCD of 45}\implies \cfrac{5\cdot 76-9\cdot 17}{45}
\\\\\\
\cfrac{380-153}{45}\implies \cfrac{227}{45}\implies \boxed{5\frac{2}{45}}
\\\\\\
5\frac{2}{45}\implies \cfrac{5\cdot 45+2}{45}\implies \cfrac{227}{45}$
