Answer:
x=2; y=-1
Step-by-step explanation:
Hello,
(1) 6x+7y=5
(2) 2x-3y=7
We multiply equation (2) by 3, it gives
6x-9y=21 and we subtract from (1)
6x-9y-6x-7y=-16y=21-5=16
So y = -1
we replace in (1) 6x-7=5 <=> 6x=7+5=12 <=> x =12/6=2
thanks
X = 79/36
Y = -7/6

2.5 kilograms
10 rings times each weight ring(250)=2500
2500 grams to kilograms is 2.5
1100 mm = 1.1 m, and 900 mm = 0.9 m.
So the area is 1.1 x 0.9 = 0.99 m^2
