Answer: 60
Step-by-step explanation:
As JH=22 and JK=82, this means HK=60.
The solutions of the equations for x are given as follows:
a. x = 36.
b. x = 15.
<h3>What is the solution for item a?</h3>
The equation for item a is given by:
x/3 - 5 = 7
Isolating x, we have that:
x/3 = 12
x = 3 x 12
x = 36.
<h3>What is the solution for item b?</h3>
The equation for item b is given by:
x/2 - 5 = 2.5
Isolating x, we have that:
x/2 = 7.5
x = 7.5 x 2
x = 15.
Hence the solutions are:
a. x = 36.
b. x = 15.

The scuba diver's position relative to sea level after the 4.6 minutes is 5.1 ft.
Given:
A scuba diver descends in the water at a rate of 23 1/2 feet per minute for 2.6 minutes.
A scuba diver ascends at a rate of 28 feet per minute for 2 minutes after seeing a big fish.
To find :
The scuba diver's position relative to sea level after the 4.6 minutes.
Solution:
Rate of a scuba diver descending in the water for 2.6 minutes = 

Distance covered by a scuba diver in 2.6 minutes = 

Rate of a scuba diver ascending for 2 minutes = 

Distance covered by a scuba diver in 2 minutes = 

The position of scuba diver after 4.6 minutes relative to sea level:

The scuba diver's position relative to sea level after the 4.6 minutes is 5.1ft.
