1 answer:

$\bf (\stackrel{x_1}{19}~,~\stackrel{y_1}{-16})\qquad (\stackrel{x_2}{-7}~,~\stackrel{y_2}{-15}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-15}-\stackrel{y1}{(-16)}}}{\underset{run} {\underset{x_2}{-7}-\underset{x_1}{19}}}\implies \cfrac{-15+16}{-26}\implies -\cfrac{1}{26}$

A wooden flooring strip is 20 1/2 inches long. If you cut off 4 3/4 inches from one end what will be the new length of the strip

KonstantinChe [14]

Length of wooden flooring strip = $20\frac{1}{2}$ or $\frac{41}{2}$

Length of strip cut off = $4\frac{3}{4}$ or $\frac{19}{4}$

So, the new length of the strip will be=

$\frac{41}{2}- \frac{19}{4}$

= $\frac{82-19}{4}=\frac{63}{4}$

Hence, the new length of the flooring strip will be $\frac{63}{4}$ inches and in mixed fraction it will be $15\frac{3}{4}$ inches.

write an expression to represent the area of a pool whose length is 5x + 1 unit and the width is 10 units

STALIN [3.7K]

Area=length x width. Thus you would do 10 x (5x+1). You have to multiply both 5x and 1 by 10 to correctly distribute. So the final equation would be area=50x+10.

-3 1/6 divide by (-2 1/3)

marshall27 [118]

Answer:

1 5/14

Step-by-step explanation:

-3 1/6 / -2 1/3

-3 1/6 = -19/6

-2 1/3 = -7/3

-19/6 / -7/3 = -19/6 x -3/7

-19 x -3 = 57

-6 x -7 = 42

57/42 = 1 5/14
