Answer:
$32.50
Step-by-step explanation:
y · 80 = 26 · 100
80y = 2600
80y ÷ 80 = 2600 ÷ 80
y = 32.5
The answer for this would be A. the radius
Answer:
8+24=2x+6
32= 8x

Answer:
x = -3, y = 1
Step-by-step explanation:
To find the value of x and y, find the determinant of original matrix, which would be 21.
Then, substitute the value of x with the solutions to the equations and find the determinant of that matrix, which is -63.
Cramer's rule says that Dx ÷ D is the value of x. So, -63 ÷ 21 = -3.
So, the x-value is -3.
You can find the determinant of the y-value in the same way, and you'll find out that y = 1.
Hope this helped! :)
