Well if there are 3 outcomes just add the two other outcomes and subtract from 1
so 0.4+0.25=0.35
so the third outcomes has a 0.35 chance of happening or 35%
20*6=120seconds +3600second in an hour so 3600*4=14400
1210+14400=14520
14520 is the answer I hope this helps!
<span>3x+4=y+5, then y+5=3x+4
It is called: reflexive property
-----------------------------
</span>
<span>x = y and y = 10, then x = 10
It is called: equality substitution property

The answer is $85.50
57 x 50% or 57 x .5 = 28.50
Add $28.50 to $57 and you get $85.50
35 = 45 - n
think of it as money
45 dollars take away how many (n) = 35 dollars
45 - n =35
or you can subtract 45 from both sides
-n = 35-45
-n = -10
divide by -1 from both sides
n = 10
