Step-by-step explanation:

Given that,

Length of the one portion of the board = x feet
Length of the another portion = (7x – 9) feet

According to the question,

$\longrightarrow$ Total length = Sum of the length of the two pieces

$\longrightarrow$ Total length = {x + (7x – 9)} feet

$\longrightarrow$ Total length = {x + 7x – 9} feet

$\longrightarrow$ <u>Total length = (8x – 9) feet</u>

Therefore, the total length of the board as a simplified expression in x is (8x – 9) feet.

Alborosie

Answer:

Step-by-step explanation:

$3x - 2y = 12 \\ 2x + 2y = 3 \\ 2y = 3 - 2x \\ 3x - (3 - 2x) = 12 \\ 3x - 3 + 2x = 12 \\ 5x = 15 \\ x = 3 \\ 2y = 3 - 6 = - 3 \\ y = - \frac{3}{2}$

katrin2010 [14]

Answer:

T = 9

Step-by-step explanation:

SAMDEB

1. Subtract 7 from both sides. 6T + 7 - 7 = 61 - 7

2. 6T = 54

3. Divide both sides by 6, to isolate T. 6T ÷ 6 = 54 ÷ 6

4. Therefore, T = 9
