lisa drank 1/3 quart of orange juice and lane drank 1/2 quart of orange juice. how many quarts did they drink together

mezya [45]

Answer:

$\frac{5}{6}$ quarts

Step-by-step explanation:

Total amount of drinks = $\frac{1}{3}$ + $\frac{1}{2}$

You would want to make the denominators the same before adding them, so I will multiply the first fraction by 2 and the second one by 3 so their denominators are 6.

$\frac{1}{3}$ + $\frac{1}{2}$ = $\frac{2}{6}$ + $\frac{3}{6}$

Now we can directly add them together while keeping the denominator the same.

$\frac{2}{6}$ + $\frac{3}{6}$ = $\frac{5}{6}$ quarts

3x3-27x=0<br> Solve by factoring a

Eddi Din [679]

After factoring $3x^3-27x=0$ the solutions are x=0 , x=3, x= -3

Step-by-step explanation:

We need to solve by factoring:

$3x^3-27x=0$

Solving:

$3x^3-27x=0$

Taking 3x common:

$3x(x^2-9)=0$

Now using formula $a^2-b^2=(a-b)(a+b)$

$3x((x)^2-(3)^2)=0\\3x(x-3)(x+3)=0$

$3x=0\,\,and\,\,x+3=0\,\,and\,\,x-3=0\\x=0\,\,and\,\,x=-3\,\,and\,\,x=3\\$

So, After factoring $3x^3-27x=0$ the solutions are x=0 , x=3, x= -3
