Hello, I will try my best to explain this to you as simple as possible.
First, you have to pass the -4 to the other side, like this:
-3 1/2x - 4 = -38 1/8
↓
-3 1/2x = -38 1/8 - 4
Then, you have to subtract -4 from -38 1/8, like so:
-3 1/2x = -38 1/8 - 4
↓
-3 1/2x = -42 1/8
My preferred method for this next step is this:
-3 1/2x = -42 1/8
↓
-7/2x = 337/8
Then, we divide:
-7/2x = -42 1/8
↓
x = (-337/8) / (-7/2)
x = 12.0357142857
So, the answer is: 12.0357142857.
Hope this helped! c:

Answer:
3
Step-by-step explanation:
3(1)-2= 1
2(1)+1 = 3
1/2 = 2m
2m/2 = 1/2 divided by 2
1/2 * 1/2 = 1/4
m = 1/4
m = 0.25
Answer: m = 1/4 or 0.25
Answer:
6.7% decrease each day
Step-by-step explanation:
Half life: 10 days
Fraction = 0.5^(t/10)
Where t is the no. of days
Per day: t = 1
0.5^(1/10)
0.9330329815 × 100 = 93.30329917
Decrease of: 100 - 93.30329917
= 6.696700846% each day
