A wire 20 cm long is cut into two pieces. The longer piece is 4 cm longer than the shorter piece.
Find the length of the shorter piece of wire
Let x = the shorter piece
x + x + 4 = 20
2x = 16
x = ?
Two subtracted from ten times a number is -142. What is the number
Ah, the art of wire dissection! Let's see if we can unravel this problem with a dash of humor.
To find the length of the shorter piece of wire, let's call it x. According to the information given, the longer piece is 4 cm longer than the shorter piece. So if the shorter piece is x cm, then the longer piece would be x + 4 cm.
Now here comes the tricky part: the total length of the wire is 20 cm. And since we have two pieces, the length of the shorter piece (x) plus the length of the longer piece (x + 4) should equal 20 cm.
Putting our clown arithmetic skills to good use, we have: x + x + 4 = 20
Let's simplify this equation. Combining like terms, we get: 2x + 4 = 20
Subtracting 4 from both sides, we get: 2x = 16
Finally, dividing by 2, we find: x = 8
So, the length of the shorter piece of wire is 8 cm. Ta-da! Now go spread the laughter with your wire-cutting skills.
Let's assume the length of the shorter piece of wire is x cm.
According to the given information, the longer piece of wire is 4 cm longer than the shorter piece. So, the length of the longer piece can be expressed as x + 4 cm.
The total length of the wire is 20 cm, which means the sum of the lengths of the two pieces should add up to 20 cm.
So, we can set up the equation:
x + (x + 4) = 20
Simplifying the equation:
2x + 4 = 20
Subtracting 4 from both sides:
2x = 16
Now, divide both sides by 2:
x = 8
Therefore, the length of the shorter piece of wire is 8 cm.
To find the length of the shorter piece of wire, let's assign a variable to it. Let's call the length of the shorter piece x cm.
According to the problem, the longer piece of wire is 4 cm longer than the shorter piece. So the length of the longer piece would be x + 4 cm.
Since the wire was originally 20 cm long and it was cut into two pieces, the sum of the lengths of the two pieces should be equal to 20 cm. Therefore, we can set up the following equation:
x + (x + 4) = 20
Now we can solve this equation to find the value of x, which represents the length of the shorter piece of wire.
Simplifying the equation, we have:
2x + 4 = 20
Subtracting 4 from both sides:
2x = 16
Dividing both sides by 2:
x = 8
Therefore, the length of the shorter piece of wire is 8 cm.
