How would u do 1 over 3 y + 1 over 4 = 5 over 12? I forgot my notes:(
malfutka [58]
Is it
\frac{1}{3y} + \frac{1}{4} = 5
or
\frac{1}{3} y + \frac{1}{4} = 5
?

both start out the same, just remember what you do to one side you have to do to the other, so subtract both sides by 1/4, then you want to get y alone, so either divide or multiply the 3 on both sides! let me know which it is and I can help you out more

[edit] it's the second, and not going to use cross multiplication.
added a picture that walks you through it :)

How do I work this out
alukav5142 [94]

9514 1404 393

Answer:

  no, it is good for 2 weeks (almost 3)

Step-by-step explanation:

The volume of the pool is ...

  V = LWH

  V = (20 m)(8 m)(1.8 m) = 288 m³

Then the amount of chlorine powder needed for 1 week is ...

  (300 g/(50 m³)) × (288 m³) = 1728 g

A box of 5000 g holds enough chlorine for ...

  (5000 g)/(1728 g/treatment) = 2.89 treatments

A box of chlorine powder is enough for 2 weeks, not 4.

Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much
Sauron [17]

Answer:

3/4 of the pot left.

Step-by-step explanation:

If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.
