Answer:
The measurement found using Ruler 2 is more accurate and more precise.
Step-by-step explanation:
Ruler 1 has fewer tick marks, Ruler 2 has more which indicates a more precise, exact, accurate reading.
The values of x and y that are solutions to the simultaneous equations are; x = -11 and y = -4
<h3>How to Solve Simultaneous Equations?</h3>
We are given the simultaneous equations;
4x - 6y = -20 -----(eq 1)
-2x + 4y = 6 -----(eq 2)
Multiply equation 2 by 2 and eq 1 by 1 to get;
-4x + 8y = 12 -----(eq 3)
Add eq 3 to eq 1 to get;
2y = -8
y = -4
Thus;
4x - 6(-4) = -20
4x + 24 = - 20
4x = -20 - 24
4x = -44
x = -44/4
x = -11
Thus, the values of x and y that are solutions to the simultaneous equations are; x = -11 and y = -4
