I think the answer is $2.01 per 1ft of redwood and pine

282/2
=141

$141/70ft ÷ 70/70
=$20.1 per 1ft

Just an answer and simple explanation! Thank you.
vazorg [7]

Answer:

15

Step-by-step explanation:

If CD and DE equal, then x+6 = 4x -21

So if you subtract x from both sides and plus 21 to both sides, that would be 3x = 27. Divide by 3 on both sides and you get 9.

Plug in x+6 with 9 and you get 15.

Solve to find the answer of blue pills Mr body took: number of blue pills, b, mr mattics give him was 3 more than the number of
barxatty [35]

Answer:

Mr body took 9 blue pills

Step-by-step explanation:

Total number of pills consumed = 17

Number of blue pills, b = 11

Number of blue pills, b = g + 3

So that,

b = g + 3

11 = g + 3

g = 8

Total number of pills recommended = b + g

                                                            = 11 + 8

                                                            = 19

Total number of pills consumed = 17

Thus,

Number of blue pills consumed = 17 - 8

                                                     = 9

Therefore, Mr body took 9 blue pills.
