Answer:
12
Step-by-step explanation:
194-50=144
144/12=12
12 hours
We can start with an equation: 12x+50 = 194 (x being number of hours)
solving gives 12x = 144
x = 144/12
x = 12
32m²
thanks me later ,correct me if I'm wrong
41,600yd's is the area....
f^-1(z) = 2z/z-1
If we multiply the top equation by -4 we can get rid of the x so:
-4x+20y=-12
4x-4y=12
Add these up
16y=0
Y=0
X=3
