Step-by-step explanation:
<u>Step 1: Define</u>
-1.6 - 2x = 5x + 0.9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 2x on both sides: -1.6 = 7x + 0.9
- Subtract 0.9 on both sides: 2.5 = 7x
- Divide 7 on both sides: 0.357143 = x
- Rewrite: x = 0.357143

Answer:
<u>23</u>
Step-by-step explanation:
The 12 hour clock doesn't go past 12 on the first 2 digits (hour).
The 24 hours goes 13:, 14:, 15: and so on.
We now have to figure out "4" largest numbers on the 12-hr clock and add them to get the max sum out of them.
The hours are:
00
01
02
...
09
10
11
12
The largest sum would be that of "09"
Now, the minutes:
59 is the highest minute and that will give us the highest sum
So, the time we are looking for is:
09:59
The sum is:
0 + 9 + 5 + 9 = <u>23</u>

Answer:
0.155
Step-by-step explanation:
nth term of a geometric sequence = ar^n-1
Where,
a = first term
r = common ratio
n = number of terms
Given:
100, 80, 64,...
a = 100
r= 80/100
= 4/5
30th term of a geometric sequence = ar^30-1
= ar^29
= 100 × (4/5)^29
= 100 × (0.8)^29
= 100 × 0.00155
= 0.155
Therefore,
30th term of the geometric progression = 0.155
