Scarlet has $85 to spend at the pet store. She is definitely buying a catfish for $12, a rainbowfish for $13, and a betta fish f

ikadub [295]

Subtract the total of the 3 fish she is buying from the amount of money she has:

85 - (12 + 13 + 14) = 85 - 39 = 46

She has $46 to spend on crabs.

Divide the amount she has to spend by the price on one crab:

46 / 8 = 5.75

Since it isn't a whole number you need to round down, since she cant buy 0.75 of a crab.

She has enough money to buy 5 crabs.

Answer:

The answer to your question is $\frac{2}{3}$

Step-by-step explanation:

Here, there is a difference of squares, so just solve it and simplify

$( 1 + \frac{1}{\sqrt{3} } ) (1 - \frac{1}{\sqrt{3} } )$

Multiply the binomials

= 1 - $\frac{1}{3}$

Simplify

= $\frac{3 - 1}{3}$

= $\frac{2}{3}$
