A bowl of Pho soup costs $7.25. The cost of the small bowl was $5 and it had 3 ingredients. What was the cost of each ingredient? (each ingredient was the same price).

$0.75 for each ingredient

Step-by-step explanation:

Subtract the cost of the bowl from the total cost (7.25 - 5.00 = 2.25)

Then divide 2.25 by 3 (because there are three ingredients) the answer is 0.75 and add the dollar sign!

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.

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0
