Answer:
Step-by-step explanation:
If J can paint a room in 3 hours, in 1 hour she gets
of the job done.
If A can paint a room in 4 hours, in 1 hour she gets
of the job done. We need to find out how long it takes them if they paint together. The equation for this is:
where x is the number of hours it takes them to get the job done together. Multiply everything through by 12x to get
4x + 3x = 12 so
7x = 12 and
x = 1.7 hours to get the room painted together.
If you mean x^2=36, then the answer is -6 or 6
H=2f/m+1
subtract one from both sides
h-1=2f/m
multiply m to both sides
m*h-1=2f
divide 2 both sides
mh-1/2=F
