A water cooler can hold 50 pt of water.
Nookie1986 [14]

Water cooler holds = 50 pt of water

1 L≈1.06 qt (which is the value of US liquid quart)

1.06 qt = 2.12 pt (which is the value of US liquid pint)

So when we are calculating how many liters of water cooler holds, divide the 50pt with 2.12pt

50pt/2.12pt = 23.6 Liters

<span>So 23.6 is the correct answer.</span>

Derick solves the problem below.
Gala2k [10]

As it is proved that the equation has no solution, Derick is correct

Step-by-step explanation:

Given

-3(4n + 2) = -4n + -2 (4n - 6)

We have to solve the equation in order to check if Derick was solved the equation correctly or not.

So,

Applying distributive property first

-12n -6 = -4n -8n +12\\-12n-6 = -12n+12\\-12n+12n-6 = 12\\-6 = 12

As the variable is already cancelled in the equation there is no unique solution.

In order for an equation to have infinite solutions the constant on both sides of equation should be same which is not the case in the given equation

So,

As it is proved that the equation has no solution, Derick is correct

Not sure need help ​
kvasek [131]

Answer:

X = 3

Step-by-step explanation:

So do 7-2 which equals 5. 5 times 6 because 6 is outside of the parentheses with no symbol, so that means to multiply. That would equal 30. You want your answer to equal 6, so you would want the number inside of the parentheses to be 1, so that 1 times 6 would be 6. 2 x 3 would be sixe, and then 7-6 would equal one. 1 times 6 would be 6. So there is your answer.
