You have a fifty-fifty chance, so you would expect it to land on heads five times and for it to land on tails five times. Hope this helps!
Assuming 5/2y is the fraction,
= y + 5/2y + 10
You can divide the entire fraction (both numerator and denominator) by 2
= y + 2.5/y + 10
That is as far simplified, or 'lowest terms' as it gets.

Answer:
-3/5 or -0.6
Step-by-step explanation:
First you have to get x
5x-21=2x-6
3x=15
x=5
then substitute in any of the equations with x to get the y value:
y=2x-6
y=2(5)-6
y=4
so the answer is choice B
hope this helps !
You have to make the denominator the same: 40
35/40 + 32/40 = 67/40
