Answer:
meter is difference in height between the submarine and the aircraft
Step-by-step explanation:
The height of aircraft above the surface 
meter
Depth at which the submarine lies below the surface 
meter
Depth at which the underwater robotic vehicle below the surface 
meter
Difference in height between the submarine and aircraft is equal to
meter
Find out the determinant
we have
2x-y=4
3x+y=1
so
D=(2)(1)-(-1)(3)
D=2+3
D=5
therefore
<h2>the answer is the second option</h2><h2>Verify</h2>
solution (1,-2)
equation 1 -------> 2(1)-(-2)=4 -------> 4=4 is true -----> is ok
equation 2 ------> 3(1)-2=1 -----> 1=1 ----> is true -----> is ok
Hello! I am happy to help you.
What you do for this problem is you take the total distance and divide by the times traveled.
1182 / 12 = 98.5.
The trail is 98.5 km long.
Hope this helps.
Length= 22 feet
Width= 18 feet
8-5+43/8
43 divided by 8 is 5.375.
8-5+5.375
8+0.375
The answer I got was 8.375
