Handy: 75+45(6)=345

Fixit: 135+50(6)=300+135=435.

435-345=90.

Sorry. Nice explanation, asdf!

No problem, we are here to help!

asdf is correct! Good job! 722.

We have $\frac{12}{\frac{1}{2}}=24$ times the amount of butter, so the required number of tablespoons is $24\cdot3=\boxed{72}.$

The LCM of 8 and 6 is 24 

Hint: Try to simplify the expression.

After simplifying, you should get 8x+4=4x-12x+12, so 16x=8, and x=1/2. 

CPhill is right. You can also simplify! -28r-28 becomes, -28(r+1). 

Hint: Try to group like terms. +5 and +10 change negative. 

Here, I'll solve one and you can solve the rest. Okay, I'll pick the 2nd question.

$\sqrt{14xy}\cdot \sqrt{12}\cdot \sqrt{30y}=12\sqrt{35} y\sqrt{x}$.
