Answer:
x= -1/4
Step-by-step explanation:
suppose ,
The number is x
now,
twice a number = 2 . x = 2x
The product of twice a number and six = 2x . 6 = 12x
[ "product" means the result of multiplication]
Then,
Eleven times the number = 11 . x = 11x
The difference of eleven times the number and 1/4 = 11x - 1/4
= (44x-1)/4
Hence,
12x = (44x-1)/4
=>48x = 44x-1 [multiplied by 4 on both sides]
=>48x-44x=-1 [subtract 44x on both sides]
=>4x=-1 [divide both sides by 4]
=>x= -1/4

Answer:
Step-by-step explanation:
From the given information, consider DB=x be the height of the ship, BC= 50 m, then DE=50 m.
Now, From ΔABC,
⇒
Also, from ΔADE, DE=50 m, we have
⇒
Now, AC=AE+EC
⇒
⇒
⇒
⇒
Also, we know that EC=BD, therefore BD=21.14 meters.
Thus,the height of the ship= 21.14 meters.
<span>3x- 1/9 y=18
</span><span>3x- 1/9(27) =18
3x - 3 = 18
3x = 21
x = 7
