A submarine is 150 below sea level while in airplane is 375 above sea level. What is the difference between the height of the seven marine and the airplane

525 feet.

Step-by-step explanation:

Difference in height

=  375 - (-150)   Remembering that - * - = +  :-

= 375 + 150

= 525 feet.

525

Step-by-step explanation:

The submarine is 150 BELOW sea level. Hence, considering sea level as 0 as we go down below the height becomes - 150.

In contrast, the airplane is above so it's +375

To find the difference, subtract it

375-(-150) {two minus become positive}

= 375+150

525 units

x+y=90

x=30-y=x
