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: 8,500
Step-by-step explanation: To round 8,516 to the nearest hundred, first find the digit in the rounding place which in this case is the 5 in the hundreds place.
Next, look at the digit to the right of the rounding place which is 1. The rules of rounding tell us that if the digit to the right of the rounding place is less than 5, we round down and if the digit to the right of the rounding place is greater than or equal to 5, we round up.
So in this case, since 1 is less than 5, we round down.
This means that the digit in the rounding place which is 5 stays the same and we change all digits to the right of the rounding place to zero.
So we have 8,500.
Therefore, 8,516 rounded to the nearest hundred is 8,500.
Answer:
Negative Correlation
Step-by-step explanation:
As you can see in the image I added, <em>a negative correlation happens when the variables move in opposite directions, in other words, one variable increases as the other decreases.</em> We can see this correlation represented by a value of -1 slope.
