Next, find their sum. Remember to find the LCD and convert the fractions so they have like denominators.
Monday + Tuesday = Total
+
= Total <em>the LCD of 5 and 4 is 20</em>
+
= Total
+
= Total
= Total
Then, convert the improper fraction into a mixed number
=
Answer:
The lines DE and BC have the same slope, therefore the two lines, DE and BC, are parallel
Step-by-step explanation:
To prove that DE is parallel to BC, we have;
The slope, m of the lines DE and BC are found from the following equation;
Where;
(x₁, y₁) and (x₂, y₂) = (b, c) and (a + b + c) for DE, we have;
Where we have (x₁, y₁) and (x₂, y₂) = (0, 0) and (2a, 0) for BC, we have;
Therefore, because the lines DE and BC have the same slope, the two lines DE and BC are parallel.
