Answer:
61 , 63 , 65 , 67
Step-by-step explanation:
Let the least even number be denoted by x. The sum of the four consecutive even numbers would be:
(x) + (x + 2) + (x + 4) (x + 6) = 256
First, simplify. Combine all like terms:
x + x + x + x + 2 + 4 + 6 = 256
4x + 12 = 256
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, subtract 12 from both sides of the equation:
4x + 12 (-12) = 256 (-12)
4x = 256 - 12
4x = 144
Next, divide 4 from both sides of the equation:
(4x)/4 = (144)/4
x = 144/4
x = 61
61 is your first number. Find the next 3 consecutive numbers:
x = 61
x + 2 = 63
x + 4 = 65
x + 6 = 67
Check:
61 + 63 + 65 + 67 = 256
256 = 256

Answer:
600 minutes or 10 hours
Step-by-step explanation:
We can solve this problem by looking at the net increase per minute. To find this, we can set rates for each value.
The pipe will be able to fill 1/120 of the tank in a minute, and the drain will drain 1/150 in a minute. So subtract the two:
1/120 - 1/150 = 1/600 of the tank per minute
Therefore you need 600 minutes to fill the tank, or 10 hours.
