Answer:

x = ±4

Step-by-step explanation:

3x^2 =48

Divide by 3

3x^2/3 = 48/3

x^2 = 16

Take the square root of each side

sqrt(x^2) = ±sqrt(16)

x = ±4

Answer:

x = ± 4

Step-by-step explanation:

You need to get x^2 by itself, and to do this, you divide both sides by 3, like so:

3x^2 = 48\\x^2 = 16

Now take the square root of both sides:

\sqrt{x^2} =\sqrt{16} \\

x = ± 4

Step-by-step explanation:

The ingredients for a fizzzy drink is 5 parts lime juice and 3 parts lemonade

Therefore, we have a total portion of 5 + 3 = 8 parts

Since there ar more parts of lime juice per fizzy drink, we calculate based on lime juice

Also dividing the proportions by we get

5/5 part lime juice and 3/5 parts lemonade or

1 part lime juice and 3/5 parts lemonade or

Thus we have 300 ml lime juice and 3/5× 300 ml lemonade or

300 ml lime juice and 180 ml lemonade = 480

The greatest amount of fizzy drink he can make = 480 ml.

Sam works 1/5 hour at the register of a store. He works 2/3 hour in the back stock room and 1/2 hour helping customers. How many
AleksandrR [38]

Answer:

Sam worked  \frac{41}{30}  hours that day (fractional answer)

Step-by-step explanation:

The total number of hours Sam worked is the sum of all the three hours given.

Let's add the first 2 using LCM and then add that result with the last.

Firstly:

\frac{1}{5}+\frac{2}{3}\\=\frac{1(3)+2(5)}{15}\\=\frac{13}{15}

Now,

\frac{13}{15}+\frac{1}{2}\\=\frac{13(2)+1(15)}{30}\\=\frac{41}{30}

The hours worked by Sam is 41/30 hours (fractional answer).
