Answer:

-21

Step-by-step explanation:

-6x + 2y = -18.........(i)

-3x - 2y = 54...........(ii)

add equ.(ii) to equ. (i)

(-6x + [-3x]) + (2y + [-2y]) = -18 + 54

-9x = 36

x = -4

sub x= -4 into equ (i)

-6(-4) +2y = -18

24 + 2y = -18

24 +18 = -2y

42 = -2y

y = -21

You are a contractor who is installing a new wooden fence for a customer. The dimensions of the fence are 20 feet long and 6 fee
ahrayia [7]

Answer:

$132

Step-by-step explanation:

First we need to find the total number of woods required. This would be total area of fence divided by area of each wood. Remember to convert inch into feet.

\frac{area of fence}{area of wood} \\=\frac{20 * 6}{6 * 0.3333} \\= 60 woods plank

Now we know the total number of planks, we need to find what is the cost of each plank. We know that one wood plank area is 2 sq. ft ( 6*0.33333). Therefore, the cost of each plank is = cost per area(sq.ft) multiply by total area (sq. ft).

cost per plank = 2 * $1.10 =$2.20.

We have total planks = 60 units and we have cost per plank = $2.20.

So, we can find total cost as 60*2.20= $132
