Find out how many liters are used in the old toilet in a year;
4×27= 108 l (in a day)
365×108= 39420 liters (in a year)
Find out how many liters are used in the new toilet;
4×6=24 (in a day)
24×365=8760 l (in a year)
Find the water saved; 39420-8760
= 30660 l saved.
Hope I helped :)
To solve an equation like this, we simply need to isolate the variable and simplify. We can do this by performing the reverse operations on both sides of the equation, so that it does not change the value of the equation but rather the form it is written.
a+5=-5a+5
+5a +5a
6a+5=5
-5 -5
6a=0
/6 /6
a=0
Therefore, in this equation, a=0.
Step-by-step explanation:
x - 1 = - 3x - 14
Bringing like terms on one side
x + 3x = -14 + 1
4x = - 13
x = - 13/4
