Solve the equation 4*e+2=1 (mod5)

Here's a way to do it.

Let 4e +2 = 5n +1 . . . . . . for some integer n

Then e = (5n -1)/4 = n + (n -1)/4

We want (n-1)/4 to be an integer, so let it be integer m.

... m = (n -1)/4

... 4m = n -1

... 4m +1 = n

Substituting this into our expression for e gives

... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1

e = 5m+1 for any integer m

This is science just please look at the pic and answer if you know don’t answer if you don’t know don’t steal points
STatiana [176]

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.
