Let the unknown be x


Both the base number are 3, so we equate the exponent:




Answer: 1/6
Doubling (2 times ) the quantity (indicates a group) of a number (x) decreaded by (-) 6 (6) is less than (<) negative 36 (-36
2 times (x-6)<-36
divide both sides by 2
x-6<-36
add 6 to both sides
x<-30
I believe the answer is 1 liter every 4 hours.
The first question is.
6 + 6 = 12
n is the same thing on both sides of the equation
6 + 6 - n = 12 - n
You are taking an equal amount off both sides so the left and right sides are both equal still. Try it. Let n = 0.5
6 + 6 - 0.5 = 12 - 0.5
6 + 5.5 = 11.5
11.5 =? 11.5
They are both equal. In algebra a letter in an equation like this one can't change values if that letter is on opposite sides of the equation.

9.5 y + 600 < 900
9.5 y = 300
y < 300 / 9.5
y < 31.57
