Answer:

Fraction of the original board left = $\frac{2}{15}$

Step-by-step explanation:

Let the length of the board is = l feet

Marty saws off $\frac{1}{5}$ of a wooden board.

Length of the board left = l - $(\frac{1}{5})l$

= $(\frac{4}{5})l$ feet

He saws off $\frac{3}{4}th$ of the remaining board,

Board left = $(\frac{4}{5})l-[(\frac{4}{5})l\times (\frac{3}{4})]$

= $\frac{4}{5}l-\frac{3}{5}l$

= $\frac{1}{5}l$ feet

He finally saws off $\frac{1}{3}$ rd of the remaining board.

Board left = $\frac{1}{5}l-[\frac{1}{5}\times \frac{1}{3}]l$

= $(\frac{1}{5}-\frac{1}{15})l$

= $\frac{2}{15}l$ feet

Fraction of the original board left = $\frac{\frac{2}{15}l}{l}$

= $\frac{2}{15}$

Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his. Let r equal the number of stamps Ch

S_A_V [24]

Answer:

Option C is correct.

The expression represents the number of stamps Erykah has : 3r -6

Step-by-step explanation:

Let r be the number of stamps Chris has.

as per the given condition: Erykah has 6 less than 3 times the number of stamps in her collection that Chris has in his.

"3 times the number of stamps Chris has" means 3r

"6 less than 3 times number of stamps Chris has" which means subtract 6 from 3r i,e 3r -6

therefore, the expression 3r -6 represents the number of stamps Erykah has.
