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>

Answer:
2 * 2 * 3 * 3
Step-by-step explanation:
We are to write the value of 36 as a product of of prime factor
Factorizing 36;
2| 36
2| 18
3| 9
3| 3
| 1
Multiplying out all the factors;
36 = 2 * 2 * 3 * 3
Hence the prime factors of 36 are 2 * 2 * 3 * 3
Here is the equation you should use: x + 2x - 12 = 180
You will be solving for x.
Combine like terms then add twelve to both sides of the equation.
3x = 192
Divide by 3 on both sides of the equation.
x = 64
Now, plug 64 in the equation for x.
2(64) - 12 = 116
Answer:
Step-by-step explanation:
Width = x
Length = 2x
Area of the ground = 0.125 square mile
length * width = 0.125
2x * x = 0.125
2x² = 0.125
x² = 
= 0.0625
Width = 0.25 miles
Length = 2* 0.25 = 0.50 miles
