Step-by-step explanation:

multiply both sides of x+2y=14 by 2: 2x+4y=28

Add 7x-4y=-8 and 2x+4y=28: 9x=20

x=20/9

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4 °F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5 °F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.

Write an expression to represent the submarine’s elevation after its final dive. Then simplify the expression to find its elevation.

Answers

Answer:

-502.5 - 115 = - 617.5

63 1/4 - 2 1/5 =  

63 - 2 = 61

1/4 - 1/5 = 5/20 - 4/20 = 1/20

so 63 1/4 - 2 1/5 = 61 1/20

after the sub dove, elevation level is - 617.5 and temp is 61 1/20 F

Step-by-step explanation:

The elevation is 617.5 feet deep and the temperature is [tex]61\dfrac{1}{20}[/tex] F.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The expression for the elevation is,

E = -502.5 - 115

E  = - 617.5 feet

The temperature at this elevation is calculated as:-

⇒ 63 ( 1/4 )- 2( 1/5 )

⇒ 63 - 2 = 61

⇒ 1/4 - 1/5

⇒ 5/20 - 4/20

⇒ 1/20

T = 63 (1/4) - 2 ( 1/5 )

T = 61 ( 1/20 ) F

Therefore, the elevation is 617.5 feet deep and the temperature is [tex]61\dfrac{1}{20}[/tex] F.
