Solid is if x is greater/less than or equal to (there isn’t a symbol for it) the line and the line would be dashed if x is < or > something
Answer:
9x^2
Step-by-step explanation:
-4/x^2 6/9x
-36/9x^2 6x/9x^2
Answer:
Step-by-step explanation:
If this is just a question to simply this equation, then here's the answer.
-10 + 4n -3t +2t +n
First, add together the n's: 4n+n = 5n
Then, the "t's": 2t - 3t = -t
Since there are no other numbers, you have:
-10 + 5n - t
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
