Answer:
18,(18)%
Step-by-step explanation:
420 + 160 + 300 = 880 total trees
160 / 880 * 100% = 18,(18)%
<span>A) X + y + z = 7
B) 2x − y + z = 7
C) 3x − z = 2
</span><span>C) z = 3x -2 Substituting this into equations A) and B)
</span>
<span>A) X + y + 3x -2 = 7
B) 2x − y + 3x -2 = 7 Adding A and B
3x + 6x -4 = 14
9x = 18
x = 2
</span>Since x = 2 then
<span>A) 2 + y + 6 -2 = 7
</span><span>A) y = 1
</span>A) X + y + z = 7
<span>A) 2 + 1 + z = 7</span>
z = 4
