1 answer:
The area of the flag that Joe created is 216 cm²
Step-by-step explanation:
Joe created triangular shaped flag for his history project
- The height of the flag was 16 cm
- The base of the flag was 27 cm
∵ The flag is shaped a triangle
∵ Area of a triangle = × base × height
∵ The base of the flag = 27 cm
∵ The height of the flag = 16 cm
- Substitute these values in the rule of the area above
∴ The area of the flag = × 27 × 16
∴ The area of the flag = 216 cm²
The area of the flag that Joe created is 216 cm²

Answer:
The solution for this system is:
Step-by-step explanation:
The problem states that we have to solve this system by the elimination method
In the elimination method, we transform the system in such a way that one variable can cancel each other. With this, we find the result of the other variable. Then, we can replace the variable we found in any of the equations, and we have the value of the variable that we had initially canceled.
In this problem, we have the following system:
If we add equations 1) and 2), the variable x is going to be eliminated
Now, we can replace the value of y in any of the equations, to find x:
I will replace in equation 2)
The solution for this system is:
