If the first roll is a 4, the possibilities to add less than 8 are that the second cube roll is 1, 2 or 3.
These are 3 different events out of 6 possilbe ones, which is 3 / 6 = 1 / 2; i.e. half of times.
Then the answer is the first option: 1 / 2

Answer:
x=12
Step-by-step explanation:
5(x-8) + 15 = 35
<em>First remove the parenthesis by multiplying</em>
5x-40 + 15 = 35
<em>Add -40+15</em>
5x -25 = 35
<em>Add 25 to both sides</em>
5x=60
<em>Divide both sides by 5</em>
x=12
Now you can plug in 12 for x if you need to, it will equal 35
We know that
[Area of the regular pentagon]=5*[side length * apothem] / 2
side length=7.1 m
apothem=4.9 m
then
Area=5*[7.1 * 4.9] / 2-----------> 86.975 m²----------> 87 m²
the answer is 87 m²
