Plot each point on a graph , then count how many you need to go up and then over in this case it is 8 over 1 then calculate the y int so y= 8x -25
37.5% of her credits. 24 out of 64, divide and you get your answer. multiply by 100 to get the percentage.
4n - 3= -2n + 9
add 3n to both sides
4n= -2n +12
add 2n to both sides
6n= 12
divide both sides by 6
n= 2
Check:
4n-3=-2n+9
4(2)-3= -2(2)+9
8-3= -4+9
5=5
Hope this helps! :)
The system of equations that models the given situation is given as follows:
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable x: Number of single lawns cut.
- Variable y: Number of front and back lawns cut.
He had 25 customers, hence:
x + y = 25.
He charges $15 for a single lawn and $25 for a front and back lawn, and made a total of $475, hence:
15x + 25y = 475

Answer:
Modern uses. Roman numerals are still used today and can be found in many places. They are still used in almost all cases for the copyright date on films, television programmes, and videos - for example MCMLXXXVI for 1986.
