The sum of two numbers is 134. If three times the smaller number is subtracted from the larger number, the result is 18. Find th
Phantasy [73]

Let, larger number be x and smaller number be y.

Condition 1: The summ of two numbers is 134.

It can be written as,

x+y=134\ldots\ldots\text{.}(1)

Condition 2: If three times the smaller number is subtracted from the larger number, the result is 18.

The equation is,

x-3y=18\ldots\ldots\ldots\text{.}\mathrm{}(2)

Solving equation 1 and 2,

\begin{gathered} \text{subtract equation (2) from (1),} \\ x+y-(x-3y)=134-18 \\ x+y-x+3y=116 \\ 4y=116 \\ y=29 \end{gathered}

Out the value of y=29 in equation (1),

\begin{gathered} x+y=134 \\ x+29=134 \\ x=105 \end{gathered}

Answer:

Larger number is x=105

Smaller number is y=29.

Ezra is filling bottles of water to hand out during a race. Each bottle of water holds 16 ounces and he has 4,005 ounces of filt
Oksi-84 [34.3K]

So just by the question, we are aware that when we divide 4,005 ounces by 16, it is not going to be a pretty number - there are going to be some left over in the form of a fraction.

First we must find out how many of these bottles can be completely filled until there is only the small fraction left that is not able to fill up a bottle. So let's divide:

\frac{4,005}{16}=250.3125

And now we know that 250 bottles will be filled completely. To find the amount of ounces left over, let's see how many ounces 250 bottles is:

250*16=4,000

There are 4,000 ounces in 250 bottles. So we need to subtract our initial amount from this known amount:

4,005-4,000=5

So there are only 5 ounces of water remaining after 250 bottles are completely filled. To put this into a fraction of the original amount, we just divide by the initial amount (4,005):

\frac{5}{4,005} =\frac{1}{801}

If the question is asking for the remainder in terms of a bottle, we just divide these 5 ounces by the 16 ounces it would take to fill this bottle:

\frac{5}{16}
