Ezra will have 5 ounces of water leftover

Step-by-step explanation:

I first divided 4,005 by 16 to get 250.3125, which I rounded to 250. Then I multiplied 250 by 16 to get how many ounces Ezra used, which is 4,000. Then I subtracted that value from how many ounces she had to get how many she had leftover.

5 ounces

Step-by-step explanation:

So first what I  did was divided the amount of filtered water Ezra had by the amount of water that would fill one bottle

4,005/16 = 250.3125

So now we know that he can fill 250 water bottles meaning that this is the maximum possible number of bottles.

Next we need to know how man ounces are left over and with the 250 bottles gone we have 0.3125 of a bottle left. So to figure out how much water is left we just multiply that number by 16 (the amount needed to make one bottle) and we will have our answer

0.3125 * 16 = 5

This means that there are 5 ounces left over. Hope this helped! :)

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
