There is no illustration, so it is impossible to answer this question. I apologise.
Answer:
x = 14, y = 37.
Step-by-step explanation:
9x + 12 = 4y - 10 (exterior alternate angles are equal)
9x - 4y = -22 ..........A
The angle which is interiorly alternate to 3x is 180 - (9x + 12), so:
3x = 180 - (9x + 12) (interior alternate angles are equal)
3x + 9x = 168
12x = 168
x = 14
Substitute x = 14 into equation A:
9(14) - 4y = -22
4y = 9(14) + 22
4y = 148
y = 37.
Not easy to graph but
multily first equaiton by -2 remember to flip sign
-2x+4y>-6
add to other equaiton
2x-2x+y+4y>-6+8
5y>2
divide by 5
y>2/5
subtitute
2x+2/5>8
subtract 2/5 from both sdies
2x>7 3/5
divid eby 2
x>38/10=19/5=3 4/5
x>3 4/5
y>2/5
just shade the area in that zone, not including point (0,0)

Answer:
7%
Step-by-step explanation:
30.80%=0.308
0.308/440=0.0007%
0.0007 is the same as 7%
