Step-by-step explanation:
I would write it but I have homework too
1/9 + 1/2 = 1/x
Let x = length of time it will take both hoses to work together
Multiply both sides by 18x.
2x + 9x = 18
10x = 18
x = 18/10
x = 9/5
x = 1.8 hours
In other words, if both hoses work together, the pool can be filled in 1 hour and 48 minutes.
Answer:
1-3.6
2-4.1
3-3.2
4-5.8
5-12.7
Step-by-step explanation:
So if an equation was f(x)=x+4
you would automatically change f(x) into y
so it would y-y=x(x-x)
so you plug in the x and 4 which is the first y and x
y-4=x(x-x)
you switch the numbers around
so your final answer would be x-4
