<span>3xy+x=9
3xy = 9 - x
y = 3/x - 1/3
if x = 2
f(2) = 3/2 - 1/3
f(2) = 9/6 - 2/6
f(2) = 7/6
f(2) = 1 1/6</span>
As three hours divided by 2 is 1.5 hours, we know that to find how far the person walks in hours, we simply have to double the distance the person walked in 1.5 hours.
2.4*2=4.8
The person walked 4.8 miles in three hours.
Does that make sense?
Since we know that t = 3.4 you put 3.4 where the t is.
2 (36 - 4 × 3.4) So what you do first is multiply 4 and 3.4 which gives you 13.6
2 (36 - 13.6) then you subtract 36 and 13.6 which gives you 22.4
2 (22.4) then you multiply 2 and 22.4 which is 44.8.
So your answer is 44.8
I hope that helped!
Answer:
6
because when you subtract 6 from 6 you get 0
6 - 6 = 0
