8x + 4 = 5x - 11
Subtract 5x from both sides:
3x + 4 = -11
Subtract 4 from both sides:
3x = -15
Divide both sides by 3:
x = -5
Answer : x = -5

Answer: 42.21 km
Step-by-step explanation:
We can solve this using trigonometry, since we have the following data:
 is the the angle of elevation
 is the the angle of elevation
 is the horizontal distance between the plane and the radar station
 is the horizontal distance between the plane and the radar station
 is the hypotenuse of the right triangle formed between the radar station and the airplane
 is the hypotenuse of the right triangle formed between the radar station and the airplane
Now, the trigonometric function that will be used is <u>cosine</u>:
 because
 because  is the adjacent side of the right triangle
 is the adjacent side of the right triangle

3/5= 3 fifth size strips
You want to find an equivalent fraction with the denominator of ten, correct? Then you would multiply the fraction in a way that will allow you to have a denominator of ten.
So...
3/5*2/2=6/10
You would need 6 tenth size strips.
