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
95-4x=40+5x
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.
95-4x=40+5x
95-4(7)=40+5(7)
95-28=40+35
67=75
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.

Answer: Ethan sold more than kayla by [tex]\frac{1}{12} gallons[/tex]
Since we have given that
Quantity of lemonade sold by Ethan is given by
[tex]\frac{2}{3}[/tex] gallons
Quantity of lemonade sold by Ethan and Kayla together is given by
1 1/4 gallon = 5/4
Quantity of lemonade sold by Kayla only is given by
[tex]\frac{5}{4}[/tex] - [tex]\frac{2}{3}[/tex]
= [tex]\frac{5-8}{12}[/tex]
= [tex]\frac{7}{12}[/tex]
To get who sold more lemonade we will first make the denominator same,
Denominator of 3 and 12 = 12
So,
[tex]\frac{2 x 4}{ 3 x 4} = \frac{8}{12}[/tex]
Compare Ethan and Kayla ,
We know that
[tex]\frac{8}{12} \geq \frac{7}{12}[/tex]
So, Ethan sold more lemonade than Kayla .
By
[tex]\frac{8}{12}[/tex] - [tex]\frac{7}{12}[/tex] = [tex]\frac{1}{12}[/tex]

To solve for distance use the formula for distance d = st, or distance equals speed times time.
distance = speed x time
Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.
distance = rate x time
To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
speed = distance/time
To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
time = distance/speed

Answers
Answer:
1) a body of air with horizontally uniform temperature, humidity, and pressure.
2) the foremost part or surface of anything. the part or side of anything that faces forward: the front of a jacket.
3) A cold front is often associated with showers and thunderstorms. As it advances, often quite rapidly (50 to 65 km [30 to 40 miles] per hour), the cold air, which is relatively dense, undercuts the displaced warm air, forcing it to rise.
4) Cold Fronts. When a cold front passes through, the weather becomes significantly colder and drier. (It isn't uncommon for air temperatures to drop 10 degrees Fahrenheit or more within an hour of a cold frontal passage.) The weather map symbol for a cold front is a blue curved line with blue triangles.
5) When a cold front passes through, temperatures can drop more than 15 degrees within the first hour. Symbolically, a cold front is represented by a solid line with triangles along the front pointing towards the warmer air and in the direction of movement.
