Saw a board 5 ft 1 in. Long into six equal pieces. If the loss per cut is 1/5 in., how long will each piece be?
Pie

Answer:

The length of each piece is 0.833 ft.

Step-by-step explanation:

Length of board, L = 5 ft 1 inch

loss per cut = 1/5 inch

The board should be cut by 5 times to get the 6 pieces.

The loss in 5 cuts = 5 x 1/5 = 1 inch

So, the length of each piece is

L' =\frac{5 ft 1 in - 1in }{6}\\\\L' =\frac{5}{6}\\\\L' = 0.833 ft

Answer:

substitution method

x = 7

y = 2

Step-by-step explanation:

2x - 2y = 10

x = 7

substitute for x:

2(7) - 2y = 10

14 - 2y = 10

subtract 14 from each side of the equation:

-2y = -4

divide both sides by -2:

y = 2

X2 -5x+6<br> To solve a quadratic equation, start by factoring,
Y_Kistochka [10]

Answer:

x=2 OR x=3

Step-by-step explanation:

Given equation:

x^2 -5x+6=0

Solving the equation for 'x':

Using factorization method:

x^2-2x-3x+6=0

Making the factors by taking common:

x(x-2)-3(x-2)=0\\(x-2)(x-3)=0

x-2=0\\\\x=2

OR

x-3=0\\\\x=3
