Answer:
Part a) The fraction is
Part b) The percent is
Step-by-step explanation:
Part a)
Find the fraction
we know that
To find the fraction of the shaded part in the square divide the number of shaded squares by the total number of squares
so
Let
x-------> the number of shaded squares
y-------> the total number of squares
f-------> the fraction of the shaded part
so
In this problem we have
substitutes
Simplify

so
convert to mixed number
Answer:
Below.
Step-by-step explanation:
As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.
W then solve this equation for x then substitute this value of x in the first equation ( y = 3x + 1) to find the value of y.
