A rope 63 feet long is cut into two pieces. One of the pieces is three times longer than the other piece. Which system of equations yields the length of the short rope, s, and the long rope, l?
A) s + l = 63 l = 3s
B) s + l = 63 s = 3l
C) s + l = 63(3) l = 3s
D) s + l = 63(3) s = 3l

Answers

The system of equations that yields the length of the short rope, s, and the long rope, l will be A. s + l = 63 l = 3s

Based on the information given in the question, the equation to use will be:

l = 3s ...... i

s + l = 63 ...... ii

Substitute equation i into ii

s + l = 63

s + 3s = 63

4s = 63

s = 63/4

s = 15.75

l = 3s = 3 × 15.75 = 47.25

The correct system of equations yields the length of the short rope, s, and the long rope, l will be;

⇒ s + l = 63

And, l = 3s

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A rope 63 feet long is cut into two pieces.

The length of the short rope = s,

And, The long rope = l

Now,

Let the length of the short rope = s,

And, The long rope = l

Here, The length of rope = 63 feet

So, We can formulate;

⇒ s + l = 63

And, One of the pieces is three times longer than the other piece.

So, We can formulate;

⇒ l = 3s

Thus, The correct system of equations yields the length of the short rope, s, and the long rope, l will be;

⇒ s + l = 63

And, l = 3s

what is the answer if f(x) = 2x-4 if f(x)= -2

Answers

Answer:

x = 1

Step-by-step explanation:

Since we know f(x) = -2, we can replace f(x) with -2 in our function and then solve for x:

[tex]-2 = 2x -4[/tex]

Let's add 4 to both sides.

[tex]2 = 2x[/tex]

And then divide both sides by 2.

[tex]x=1[/tex]

And that's value of x, or the answer to our equation. Hopefully this was helpful... if you have more questions, let me know! :)

- 2.25 divided by 5 is .45 (price for one apple)

- 1.85 divided by 5 is .37 (price for one apple)

- 2.60 divided by 5 is .52 (price for one apple)

- 2.10 divided by 5 is .42 (price for one apple)

2. If you can multiply the price for one apple by the total # of apples and it matches the total cost throughout the entire graph then it's proportional.
