Solve the system of linear equations by elimination 5x-2y= -8

4x-4y=8

The solution of the system is ,

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

okay wait before i answer, is this for your points on a graph?

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
