Novay_Z [31]3 years ago
4 0

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.

Please help!! Show work please!!

1. 3x - 2y = 8 Subtract 3x on both sides

-2y = 8 - 3x Divide by -2 on both sides to get y by itself

y = -4 + 3/2x


2. a + b / 3 = 5 Multiply 3 on both sides

a + b = 15 Subtract a on both sides to get b by itself

b = 15 - a


3. 12x - 4y = 20 Subtract -12x on both sides

-4y = 20 - 12x Divide -4 on both sides to get y by itself

y = -5 + 3x


4. y + 3 = -5(x - 2) Multiply -5 to (x-2)

y + 3 = -5x + 10 Subtract 3 on both sides to get y by itself

y = -5x + 7
