If you use the law of sins, the answer would be B) 6.928 (in the law of sines you round so it would be 6.93)
If he does three hours, its 9 strips, for four, its 12, six is 18, seven is 21, and nine is 27
Answer:x=-8
Step-by-step explanation:subtract 21 from both sides then simplify 31-21 to -8
From the second:
2x-y=4
x=(4+y)/2 and applying this to first:
4+y+3y=12
4y+4=12
4y=8
y=2 and since x=(4+y)/2, x=3 so
x+y=2+3=5
Y = 12x is a direct variation which is a proportion.
As x increases y also increases.
