3x-5y =15
2x-y=-4
multiply the equation by 5 and then subtract equation 2 from equation 1
so 3x-5y =15
10x-5y =-20
-7x =35 x =-5
plug in the value of x in the second equation -10 -y =-4 - y= -4 +10 y =-6
x=-5 y=-6
Answer:
10
Step-by-step explanation:
2^2 x 5^2 = 100
root the 100 = 10
We know that
[area of circular cookie]=pi*r²
r=2.5 in
