17 or -17, that would make 1 which is an integer.
Answer:
19
Step-by-step explanation:
Since it is a 90° angle we can say that 3x-15+2x+10 = 90.
3x-15+2x+10 = 90
5x-5=90
5x=95
x=19
By solving this we find that x is equal to 19.
X * 8/100 * 1 + 9/100 * (11,000 - x) = 980
0.08 x + 0.09 (11000 - x) = 980 Now solve for x which is the amount invested at 8%
0.08x + 990 - 0.09x = 980
- 0.01x = 980 - 990 = -10
x = -10 / -0.01
x = 1000
So he invest 1000 in 8% and 10000 at 9%
