Answer:

Step-by-step explanation:
The relative change is defined by the following equation:
(1)
Where:


With this in mind, let's replace the values in the equation (1):

Answer:
from a solid to a liquid
Step-by-step explanation:
The sum of two consecutive integers is -23.
Let the larger number = x
smaller number = x - 1
Sum = -23
=> x + x - 1 = -23
=> 2x - 1 = -23
=> 2x = -23 + 1 = -22
=> x = -22/2
=> x = -11
Larger number is -11
Answer:
X = savings, p= pay per hour
X+4p = 86 - - - - (1)
X+6p=104 - - - - - (2)
Re arrange equation (1)
X=86-4p-----(3)
Substitute (3) in (2)
86-4p +6p=104
86+2p=104. (subtract 86 from both side)
2p = 18. (divide by 2 from both side)
Then p =$9
By substitute in equation (1)
X = $50
X=-11.5 and y=10.5.Thae two values are the answers.
