Water is running into a bathtub at a constant rate. after 2 minutes, the tub is filled with 2.5 gallons of water. write two equations for this proportional relationship. use w for the amount of water (gallons) and t for the time ( minutes). in each case, what does the constant of proportionality tell you about the situation?

c

step-by-step explanation:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

exa:

)

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
