If 39 = (1 3/10)b, we could simplify this by writing 39 - (13/10)b.
Solve this for b by mult. both terms by (10/13):
(10*39)
----------- = (10/13)(13/10)b. Then b = 30 (answer)
13
0.5 x 1/10 = 0.05 All you do is multiply
You could make a small (easily repaired) leak and watch it for the amount of time you need to conclude what you need to.
To find X, we can divide 5 into 40.
40 divided by 5 is 8.
Now we can do 5 x 8. That is 40.
X=40
OR we can do it another way.
40 divided by 5 is 8.
Cross out 5 divided by 5.
Now we have 8. Still.
X is 8
Yes it is. Input the numbers into the pythagorean theorem,
and if they equal each other it is a right triangle.
