If the numbers are x an y we have:-

x + y = 1
x - y = 0.7 Adding:-

2x = 1.7
x = 0.85

y = 1 - 0.85 = 0.15

Answer:- the 2 numbers are 0.85 and 0.15 Answer

Answer:

h = 400 ft

The bird is 400 ft above the submarine

Step-by-step explanation:

Given;

The submarine is 300 feet below sea level

Vertical distance between submarine and sea level h1 = 300 feet

The bird is flying at 100 feet above sea level

Vertical distance between the sea level and the bird h2 = 100 feet

The total vertical distance between the bird and the submarine is the sum of the vertical distance between submarine and sea level and the vertical distance between the sea level and the bird.

h = h1 + h2

h = 300 ft + 100 ft

h = 400 ft

The bird is 400 ft above the submarine
