I have one third gallon of juice and one sixth gallon. How many more gallons is need to make three gallons

charle [14.2K]

Answer:

2.5 gallons

Step-by-step explanation:

Make the denominators of the fractions the same and combine them

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

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

Then simplify the fraction

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

Then subtract how many gallons you have from how many you want

$3 -\frac{1}{2} = 2\frac{1}{2}$

You will need 2.5 gallons to make 3 gallons

Is -2/3(12b - 6 + 9b - 18) equivalent to 2b(b + 8)? Show your work.

AURORKA [14]

Answer:

No, they are not equivalent

Step-by-step explanation:

$\frac{-2}{3}(12b - 6 + 9b - 18) = \frac{-2}{3}(12b + 9b - 6 - 18)\\\\=\frac{-2}{3}(21b - 24)\\\\ = \frac{-2}{3}*21b -24*\frac{-2}{3}\\\\= -2*7b + 8*2\\\\= 2( -7b + 8)$
