Step-by-step explanation:
first fish tank: 95-4x
second fish tank: 40+5x
1. Define variable
The variable x represents the number of days.
2. Write the inequality
<em>95-4x=40+5x</em>
<em />
3. You probably don't need the answer but I am just going to solve.
The first fish tank will have less water than the second fish tank after 7 days.
<em>95-4x=40+5x </em>
<em>95-4(7)=40+5(7)</em>
<em>95-28=40+35</em>
<em>67=75</em>
<em>Since the first equation (95-4x) represents the first fish tank, and the second equation (40+5x) represents the second fish tank, the solution shows how the amount of water in the first fish tank is less than the amount of water un the second fish tank after 7 days.</em>
For this case what we should do is take into account the following conversion:

We then have the following number:

Applying the given conversion we have:

By doing the corresponding calculation we have that the standard form is given by:
Answer:
4540 million in standard form is:
Answer:
C
Step-by-step explanation:
Do you have a picture I'll show you
Isolate the variable by dividing each side by factors that don't contain the variable.
