The answer is 48, because 6*8=48, 16*3 = 48, 24*2 = 48.
243 liters represents 7/10 - 1/4 of the water.
v=243 / (7/10 - 1/4) = 243 / (14/20-5/20) = 243(20)/9 = 540 liters.
Answer: 540 liters
Check:
(7/10)(540) = 7(54) = 378
(1/4)540 = 135
difference = 378 - 135 = 243 good
27x^3 - 12x factors into
3(9x^3 - 4x) a common factor of three has been taken out.
3x(9x^2 - 4) a common factor of x has been taken out. 3x is not a linear factor.
9x^2 - 4 factors by means of the difference of squares
3x(3x - 2)(3x + 2)
The two linear factors are 3x - 2 and 3x + 2
Answer:
○ Subtract 8 from both sides, then divide both sides by 1/3
Step-by-step explanation:
Perhaps the usual sequence of steps is ...
add 8:
3y = 27
divide by 3 (equivalently, multiply by 1/3)
y = 9
___
If the division by 3 is done first, then the constant on the left becomes -8/3, so cancelling it requires adding 8/3 to both sides of the equation.
_____
If you do the last suggestion, you get ...
subtract 8 from both sides:
-16 +3y = 11
divide both sides by 1/3:
-48 +9y = 33 . . . . . . . does not solve the equation completely
