Answer:
Step-by-step explanation:
AD = DC and BE=EC ⇒
DE = 1/2AB
- 4x + 1 = 1/2(11x - 25)
- 2(4x + 1) = 11x - 25
- 8x + 2 = 11x - 25
- 11x - 8x = 2 + 25
- 3x = 27
- x = 27/3
- x = 9
DE = 4*9 + 1 = 36 + 1 = 37
Column A
X=9
X=8
X=7
X=84
X=4 1/6
The LCD here is 12(5) = 60.
We must rewrite <span>7/12 - 2/5 with 60 as common denominator.
Doing this, we get 35/60 - 24/60 = 11/60 (answer)</span>
For example,

They both do have the same denominator, so we can multiply them.
We need to multiply the numerators.
Next, multiply the denominators.
We then get:
1/4

If the denominators are not the same, find the LCD (Least Common Denominator) of the two fractions. Then, follow above.
