Answer:
infinitely many solutions
Step-by-step explanation:
We want to find solution to the system:
-4y=-20x+40
y+10=5x
We make y the subject in the second equation to get;
y=5x-10
We substitute y=5x-10 into the top equation to get:
We expand to obtain;
This implies that:
Therefore the system has infinitely many solutions.

Step-by-step explanation:
You might just think that I subtracted but on the triangle the last side is the base which is always smaller.
Answer:
A = 27π cm² or A ≈ 84.823... cm²
Step-by-step explanation:
From being shown that the missing area is 90 out of 360°, we know that we need to find 75% of the area of the given circle.
Our equation is altered to: A = 0.75πr²
Plug in: A = 0.75π(6)²
Multiply: A = 27π cm²
If you were instructed to multiply pi and round (which is not as probable given that this is RSM), then the answer would be A ≈ 84.823... cm²
