Ted has two boards. The length of the second board is five inches more than two times the length of the first board. The total length of the two boards is 65 inches. How many inches long is the first board?

Length of the first board is 20 inches.

Step-by-step explanation:

Let the length of first board is x and that of second board is five inches more than two times the length of the first board.

Length of second board = 5+2x

Total length of two boards is 65 inches

ATQ,

x+5+2x=65

3x+5=65

Taking like terms together,

3x=65-5

3x=60

x = 20

So, the length of the first board is 20 inches.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
