Answer:
I think angle 7 could also measure 117, and I think the angle relationship is alternate exterior angles.
Step-by-step explanation:
If my answers are wrong, I am incredibly sorry!
Let amount invested at 8% per year = x
Let amount invested at 14% per year = y
Total investment is $94000 then we get equation:
x+y=94000
or
x=94000-y...(i)
Given that total return in 1 year is $8720 so we can write equation:
8% of x + 14% of y = 8720
or
0.08x+0.14y=8720...(ii)
plug (i) into (ii)
0.08(94000-y)+0.14y=8720
7520-0.08y+0.14y=8720
7520+0.06y=8720
0.06y=8720-7520
0.06y=1200
y=20000
plug value of y into (i)
x=94000-y=94000-20000=74000
Hence final answer is given by:
Amount invested at 8% per year = $74000
Amount invested at 14% per year = $20000
Answer: The answer here is x=12.49
Step-by-step explanation:
The idea is tho remove the brackets on the right hand side by multiplying by 4.9
4.90= 10(x-12)
4.90=10x-120
x=12.49
