3. A carpenter cuts a piece of lumber into two pieces. One piece is twice the length of the other.
If the longer piece is 28 inches long, how long
was the whole piece of lumber before it was cut?

write down what you know. Clearly, the two pieces have lengths

x and x+6

The longer piece is obviously x+6, so you also know that

4/5 (x+6) = 28

Now you can find x.

42 inches

Step-by-step explanation:

Let x represent the length of the shorter piece then...

2x=28

Divide both sides by 2

x=14

The shorter one is 14 inches long and the longer one is 28 inches long. Now, we add these two numbers to find the original length of the lumber.

14in+28in=42 inches

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
