Step-by-step explanation
The associative property of addition states that how number of groups won't change the answer.

In this example, both answers are equal to 7.
In the given problem, '0-7+ (19 + 5) = (-7 + 19) + 5' is the best choice because the order of the parenthesis is being changed, yet the answer is still the same.

10 divided by 10 is 1
So 1 is 10%
1 divided by 2 = 0.5 Is 10% divided by 2 = 5%

What is logarithm ?When you raise a number with an exponent, there comes a result.
Lets say you get

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = \log_a(c)[/tex]
Log with base 10 is written as [tex]\log(x)[/tex] mostly.
For the given equation, using the above definition, we get:

Identify the relation that is a function. city name to state name number of apples purchased to the cost of the apples days of the week to the months of the year last name to phone number
Answers
Answer:
number of apples purchased to the cost of apples
Step-by-step explanation
The only relation that is a function is number of apples purchased to the cost of the apples.
A relation is considered a function if each input (domain element) is associated with exactly one output (range element). Let's analyze the given relations:
City name to state name: This is not necessarily a function. Multiple cities can be in the same state.
Number of apples purchased to the cost of the apples: This is a function. Each number of apples purchased is associated with a single cost of apples.
Days of the week to the months of the year: This is not a function. Some days of the week might correspond to multiple months.
Last name to phone number: This is not necessarily a function. Different people with the same last name could have different phone numbers.

Answers
The total monthly income of Delisile including her spendings is R 1,520,000
How to find Delisile monthly incomeGiven:
x = Total monthly incomeAmount spent on rent = 39% of x= 0.30x
Amount remaining = x - 0.30x
= 0.70x
Amount spent on food and traveling = 50% of 0.70x
= 0.50 × 0.70x
= 0.35x
Amount spent on education = R 220,000Amount left = R 312,000Total = rent + food + education + amount left
x = 0.30x + 0.35x + 220,000 + 312,000
x = 0.65x + 532,000
x - 0.65x = 532,000
