C
Step-by-step explanation:
x+2y=8x...............
Answer:x = 6/5
Step-by-step explanation:
The given expression is
2/3+1/5x=5/6
The Lowest common multiple of 2, 5x and 6 is 30x. We would multiply the left hand side of the equation and the right hand side of the equation by 30x. It becomes
2/3 × 30x + 1/5x × 30x = 5/6 × 30x
= 20x + 6 = 25x
Subtracting 20x from the left hand side and and the right hand side of the equation, it becomes
20x - 20x + 6 = 25x - 20x
5x = 6
x = 6/5
Answer:
x = 0.6623
y = 8
Image is attached for refernce of my solution
Step-by-step explanation:
In Δ DEF
By applying pythagoras theoram,
DE = 
=
∴ DE = 8
In Δ ABC
BC = y = 12 sin 30° = 6
AC = 
+ DE + x = + 8 + x = 12 cos 30°
⇒ 9.73 + x = 10.39
<h3>⇒ x = 0.6623</h3>
