Using sine formula we have
8/sin60 = x/sin30
hence x= 8/√3 = 4.62
Answer:
8) 4(n)+12
9) 21 + 4(m) + (2(m)+7)
10) 3 (S+21)
Step-by-step explanation:
I did this quickly, hopefully they are correct. May not be the same format as you wish (especially for 9)
Select any two coordinates from the graph such as (7,4) and (9,7). The formula of slope is rise/run or y2-y1/x2-x1
(4-7/(7-9)=(-3)/(-2)= 1.5
The slope of the graph is 1.5!
The answer is 6,000 welcome
15x+$38.50=$100
x being however much she can spend on each friend
x= $12.30 if you need that too
