Find the quotient of 21x^2y^6+6xy^3-30xy/3xy.

kaheart [24]

$\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------$

$\bf \cfrac{21x^2y^6+6xy^3-30xy}{3xy}\implies \stackrel{\textit{distributing the denominator}}{\cfrac{21x^2y^6}{3xy}+\cfrac{6xy^3}{3xy}-\cfrac{30xy}{3xy}}
\\\\\\
\cfrac{21}{3}\cdot x^2x^{-1}y^6y^{-1}+\cfrac{6}{3}\cdot x^1x^{-1}y^3y^{-1}-\cfrac{30}{3}\cdot x^1x^{-1}y^1y^{-1}
\\\\\\
7x^{2-1}y^{6-1}+2x^{1-1}y^{3-1}-10x^{1-1}y^{1-1}\implies 7xy^5+2y^2-10$

Solve for x <br><br> 5(x+1)=5x+2

yaroslaw [1]

Steps:
1. Multiply what is in the parentheses
5x + 5 = 5x + 2
2. Subtract 5x on each side
3. 5=2
4. 5 doesn't equal 2 so the equation doesn't have a solution or it is not true.

An 8-pint container of window cleaner costs $17.12. What is the price per cup?

Mazyrski [523]

Remember that 1 pint equals two cups
So, if you do 17.12 times eight, you get 136.96, and you need half of that so you do that divided by 2 and you get 68.48.
