Mrs. Tomas is installing a fence around the perimeter of her garden. The perimeter of the garden is 36 feet. Each section of the fence is 3 feet long and costs $24. Write an equation that can be used to find c, the cost of the sections of fence she needs for her garden, and then solve for c.

C = (36/3)* $24

C = $288

Step-by-step explanation:

In this question, we are asked to write an equation for cost c of the section of fence needed for the garden and the solve for the value c.

C is already assigned as the cost of the sections she needs for her garden.

We were made to understand that the perimeter of the garden is 36 feet, with a 3 feet each section. Now, what we need to do is to know the number of sections that we have. Since, each section is 3 feet, and the total perimeter is 36 feet, this means that the total number of sections needed would be 36/3. Each of the section as we were told costs $24, so we can then proceed to calculate the value of C from there.

C = (36/3)* $24

This is the equation that gives the cost. The actual value of the cost is thus:

C = 12 * 24 = $288

The total cost of the sections if the Fence is $288

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
