Answer:
A. t=13 B. K= 23 C. t= 1 3/8
Step-by-step explanation:
A. 2t-30m=20
30 x 1/5= 6
2t-6+6=20+6
2t/2=26/2
t=13
B. 14+m=2k
14+12=2k
14+12=46
46/2=23
k=23
C. 1/8r+t=1
1/8 x (-3)= -3/8
1 - (-3/8)= 1 3/8
t= 1 3/8
Hope it helps!
A total of $27,000 was invested; part of it at 10% and part of it at 12%. The total yield was $2990. How much was invested at each rate?
Let
x -----> amount invested at 10%
(27,000-x) -----> amount invested at 12%
we have that
0.10(x)+0.12(27,000-x)=2990 ------> equation A
solve for x
0.10x+3,240-0.12x=2,990
0.12x-0.10x=3,240-2,990
0.02x=250
x=$12,500
so
27,000-x=27,000-12,500=$14,500
therefore
amount invested at 10% ----> $12,500
amount invested at 12% -----> $14,500
Answer:
Step-by-step explanation:
1)
We can find an open interval 
. Which contains the closed interval ![[0,1]](https://tex.z-dn.net/?f=%5B0%2C1%5D)
when 
Therefore, the intersection of all the open intervals containing ![[0,1[/tex[ is [tex][0,1]](https://tex.z-dn.net/?f=%5B0%2C1%5B%2Ftex%5B%20is%20%5Btex%5D%5B0%2C1%5D)
2)
We can find closed intervals containing in when
Since is closed, the intersection of all those intervals containing ![[0,1[/tex[ is the closed interval [tex][0,1]](https://tex.z-dn.net/?f=%5B0%2C1%5B%2Ftex%5B%20is%20%20the%20closed%20interval%20%5Btex%5D%5B0%2C1%5D)
Okay so to get this answer u have too Take 17 and subtract 2 This equals 15, So the answer would be 15, This is how I get my answers at least
