Answer: (D) \frac{y-x}{y+x}

Explanation:

\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}=\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}=\frac{y-x}{y+x}

Just a note on writing down these expressions: I recommend using parentheses whenever you can to avoid misinterpretation. An expression 1/x-1/y / 1/x+1/y could be interpreted by someone as 1/x-(1/y / 1/x)+1/y, which is a different thing.

Kasey and her sister both sold cookie dough. Her sister sold three times as many tubs of cookie dough. If they sold a total of 8
Rufina [12.5K]
X= number of tubs Kasey sold
3x= number tubs sister sold

Add the number sold by Kasey and her sister to equal the total sold (88).

x + 3x= 88
combine like terms

4x= 88
divide both sides by 4

x= 22 number tubs Kasey sold


Number Sold by Sister
3x= 3(22)= 66


CHECK:
x + 3x= 88
22 + 3(22)= 88
22 + 66= 88
88= 88


ANSWER: Kasey sold 22 tubs and her sister sold 66 tubs.

Hope this helps! :)

Ratling [72]

Answer:

Basketball 300

Football 100

Baseball 50

Soccer 150

Step-by-step explanation:

Half of the students would choose basketball

so 600/2 = 300

Half of the remaining students would choose soccer

so 300/2 = 150

2/3 of the remaining students would choose football

so 150 x 2/3 = 100

1/3 of the remaining students would choose baseball

150 x 1/3 = 50
