600,000 + 3,800 = 603,800
Answer:
$2.24
Step-by-step explanation:
Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.
The tip would be 2 dollars and 24 cents. ($2.24).
Answer:
An inequality often covers an infinite area. Depending on the problem, any area either below or above the function is included in the set of solutions.
For example, see the attached photo.
y < x is graphed here.
When you substitute x = 0 into the function, y will equal 0 and this point is a solution to the problem. However, if any point under this line, such as (1, 0), (-9, 0), or even (1000000000, 0), was chosen, these are still solutions to the inequality, but not the problem.

Answer:
Nadia is incorrect, please check explanations for the correction to her work
Step-by-step explanation:
Here, we want to validate the wok of Nadia
Let the number be n
5 times the number is 5 * n = 5n
Difference between 5n and 3 less than twice the number
3 less than twice the number is 2n-3
So it should be 2n-3 ;
The solution is thus;
5n - (2n-3) = 18
5n - 2n + 3 = 18
3n + 3 = 18
3n = 18-3
3n = 15
n = 15/3
n = 5
