Answer:No the student was not right.Neither of the estimations were right because she did not estimate at al.
Step-by-step explanation:
1.Round 49 to the nearest ten: 50.
2.Round 184 to the nearest ten:180.
3.Add 50+180 to get 230.
The student was not right because she did not estimate 49 nor 184.

The line 5x − 2y = −6 <=> 2y = 5x + 6 <=> y = (5/2)x + 3, has the slope a = 5/2
=> Another line (y = a'x + b) that is perpendicular with this line, must has slope a', that satisfies: a' x (5/2) = -1 => a' = -2/5
=> y = (-2/5)x + b
This line passes (5, -4), then we have:
-4 = (-2/5)*5 + b => -4 = -2 + b => b = -2
=> Solution is y = (-2/5)x -2
Hope this helps!

The answer is 5/42. 1 x 5/7 x 6 = 5/42.
2(x-6y+4z=2)
2x+4y-8z=16
2x-12y+8z=4
2x+4y-8z=16
4x-8y=20
x-2y=5
4x-8y=20
-4x+8y=-20
