Answer:
z=3m-2n
Step-by-step explanation:
1000^m/100^n=(10³)^m/(10²)^n
=10^3m/10^2n
10^z=........
z=3m-2n ................
Answer:
n=30
Step-by-step explanation:
1/4(n+2)=8
1/4n+2/4=8
1/4n+2/4-2/4=8-2/4=7 2/4
1/4n=7 2/4
1/4n (4)=7 2/4 x (4)
n=29+2=30
Amount = 10,500(1 + 0.0299) ^ 5
= 12,166.47
Answer: Hence, Option (6) and (8) are correct as their value is also "-8".
Step-by-step explanation:
Since we have given that
First we need to solve to get the value of 'x' :
Therefore, x=-8
Now, we will check all the options :
1) 4x+8=24
2) 9x+18=-24
3) 4x+12=-24
4) 18x+36/2=-24
5) 4x=-36
6) 4x=-32
7) x=-9
8) x=-8
Hence, Option (6) and (8) are correct as their value is also "-8".
