Answer:
x=4
y=10
Step-by-step explanation:
3x +3y = 27
x - 3y = -11 (add these up so 3y will be eliminated and you'll have x only)
4x = 16
now let's eliminate x (you can put 4 instead of x though)
3x + 3y = 27
-3/ x -3y= -11 (multiple the the 2nd equation with -3 to eliminate x )
3x + 3y =27
-3x + 3y =33
6y = 60
It is D because if you look at the graph every 5 years the acres decrease by 20
Answer: 72.8
Step-by-step explanation:
If you were to fold the lines together, the lengths would have a barely different length so it is 72.8
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2).
