There are two unknowns in the problem statement above so we need two equations in order to solve this. The firs expression is that the <span>sum of two numbers is 50.

x + y = 50

The second expression is that the o</span><span>ne number is 10 less than three times the other number. 

x = 10 - 3y

Therefore, the two numbers have values 40 and 10. Hope this answers the question. Have a nice day.</span>

Ok so its a guessing game

I say its 40+10 because

40-10{one # is 10 less than)=30
10(3){three times the other number}=30

so 40+10=50

Elena is making an open-top box by cutting squares out of the corners of a piece of paper that is 11 inches wide and 17 inches l
ser-zykov [4K]

Answer:

V(x) = (17 - 2x)(11 - 2x)x

Step-by-step explanation:

We are told that She is making an open top box. This means the box will have only 5 faces.

Now, she cuts squares out of the paper that measures 11 inches wide and 17 inches long.

Now, if the square side is x, it means the width of the box will be x. Since there are 2 upright faces that serve as width.

Thus, measurement of width from the 11 inches paper = (11 - 2x)

Now, similarly, there will be 2 upright sides that will serve as length. Thus, length from the 17 inches side is;

(17 - 2x)

Now,recall that a side of the square is x.

Thus, the depth is x.

Now, volume of a box is given by;

V = length x width x depth

Thus, in this case;

V(x) = (17 - 2x)(11 - 2x)x
