You have a 45-gallon jug and a 124-gallon jug. neither of the jugs has any markings (although you do know their capacities). des
Alja [10]
Pour 4  times of 124-gallon into a big jug.
Amount of water = 124 x 4 = 496 gallons

Then use the 45-gallon jug to scoop out the water 11 times.
Amount of water scooped out = 11 x 45 = 455 gallons

Water remaining = 496 - 450 = 1 gallon.

How can you analyze connections between linear equations and use them to solve problems
Alexeev081 [22]

Answer:

Step-by-step explanation:

One of the more obvious "connections" between linear equations is the presence of the same two variables (e. g., x and y) in these equations.

Assuming that your two equations are distinct (neither is merely a multiple of the other), we can use the "elimination by addition and subtraction" method to eliminate one variable, leaving us with an equation in one variable, solve this 1-variable (e. g., in x) equation, and then use the resulting value in the other equation to find the value of the other variable (e. g., y).  By doing this we find a unique solution (a, b) that satisfies both original equations.  Not only that, but also this solution (a, b) will also satisfy both of the original linear equations.

I urge you to think about what you mean by "analyze connections."

Find the slope of a line perpendicular to y = -2/5x + 4/5
valkas [14]
To find a perpendicular line, you need to find the negative reciprocal of the slope.

-2/5 flips into -5/2
Since -2/5 is negative, -5/2 turns positive, so 5/2.

Therefore, the slope of a line perpendicular to Y = -2/5x + 4/5 is 5/2
