Mr. Trainer is building a bookcase. He has two wooden boards that are each 8 feet long. He needs to cut the wooden boards into p

love history [14]

Answer:

Step-by-step explanation:

Length of one of the boards = 8 feet

Converting to inches

$1\ \text{foot}=12\ \text{inches}\\\Rightarrow 8\ \text{feet}=8\times 12=96\ \text{inches}$

One cut is 16 inches

So, we divide the length of the board by 16

$\dfrac{96}{16}=6$

So, one board is cut into 6 pieces.

The other board is also 8 feet long.

So, the number of pieces the other board is cut into is also 6.

Hence, a total of $6+6=12$ pieces of each 16 inches long can be cut from the two boards.

Answer:

Step-by-step explanation:

(2/5)*n - 6 = 10 Add 6 to both sides

(2/5)*n - 6 + 6 = 10 + 6 Combine

(2/5)*n = 16 Multiply both sides by 5/2

(5/2)(2/5)n = 16*(5/2)

n = 80 / 2

n = 40
