Hard math problem simplify the problem .
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.
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.

What should the following rate be divided by to convert it to a unit rate?
6 inches
________
12 hours
Answer:
Unit rate is a rate that has 1 as denominator.
Given the rate: 6 inches / 12 hours, we have to divide numerator and denominator by 12 to transform the denominator in 1, as follows:
\frac{6}{12} = \frac{6/12}{12/12} =
12
6
=
12/12
6/12
= 0.5 inches/hour

No solution. If you rearrange things a bit, you have

3x-y=2
Double the 2nd equation and you have
6x-2y=4
There's no way 6x-2y can be both 10 and 4.
