Answer:
6
Step-by-step explanation:
x = 2 y = 6 Explanation: y = 3 x (1) y = x + 4 (2) Subtracting (1) - (2): 0 = 2 x − 4 2 x = 4 x = 4 2 = 2 y = 3 × 2 = 6

Answer:
$8.37
Step-by-step explanation:
2.10 - 0.84 = 1.26
4.50 - 0.84 = 3.66
3.50 - 0.84 = 2.66
2.60- 0.84= 1.76
1.26+3.66+2.66+1.76= 9.34
9.34- 1.50= 7.84
7.84 + 6.75 %= 8.3692 (rounded 8.37)
Moving to the edges it travels 2*3 + 2*2 = 10 units.
Then it moves in a circular path when it turns the 4 corners.
It goes through 90 degrees in each case - or pi/2 units
so 4 turns = 4 * pi/2 = 2 pi units
Answer is 10 + 2 pi.
