Answer:
Impossible
Step-by-step explanation:
In 5x^2-4x+3=0, standard form, substitute these values in the quadratic formula:
a = 5; b = -4; c = 3
The quadratic formula is 
(ignore the weird capital A)
Substitute a b and c:

Simplify:

Because
is the square root of a negative number, the answer would be imaginary.
Therefore, there are not solutions to this equation.
A solution is the same as the roots or zeroes, where the graph would cross the x-axis when graphed.
The graph never meets the x-axis. It looks like this:
<h3>
Answer: 2/3</h3>
Here are the outcomes that are less than five = {1, 2, 3, 4}. There are A = 4 values here.
Here are all the outcomes possible: {1, 2, 3, 4, 5, 6}. There are B = 6 ways to roll a single number cube (aka dice).
Divide the two values: A/B = 4/6 = (2*2)/(2*3) = 2/3
The fraction 2/3 is approximately equal to 0.667 which converts to 66.7%
6 9/10 is what 6.9 is in fraction form
