Hello <u>156339</u>

Since we know the amount of money is always decreasing, then we should know to subtract by 35. Because 2.25 is the cost per meal and x is the number of meals, the total cost should be 2.25x, which is correct because y is the amount of money left over.

Our final equation would be:

<u><em>y = 35 - 2.25x</em></u>

There are 3x-2 trees planted in each row of a rectangular Parcel of land. If there are a total of 24x-16 trees planted and the p
4vir4ik [10]
Let's call the number of rows 'R' . (Clever ?)

There are (3x -2) trees in each row, and there are 'R' rows,
so the total number of trees is [ R times (3x-2) ].

But the problem told you that the total number of trees is (24x-16).
So
       R(3x - 2) = (24x - 16)

For a quick, happy ending, how about factoring '8' out of the right side:

       R(3x - 2) = 8(3x - 2)

Is it jumping out at you yet ?
If not, then divide each side by (3x - 2) :

     <em>  <u> R      =      8</u></em>

There are eight (8) rows of trees.

Find the surface area of the pyramid. A pyramid has a square base and 4 edges that each rise from one vertex of the square base
fredd [130]

Answer:

767 in ^2

Step-by-step explanation:

To find the area of a square base, you multiply 17 by 17 (side lengths) to get 289.

To get the area of the other faces, you do 1/2 * 17 * 14 (triangle area formula) to get 119

Since there are four other faces, multiply 119 by 4 to get 476, and add 476 with 289 to get 767

I need help with this please
AnnZ [28]
Hi there! The answer is C.

The area of the square in the middle is the following:
length \: \times \: width \: = 5 \times 5 = 25
Hence, the area of the square is 25 cm^2.

The area of one triangle is the following:
0.5 \times base \: \times \: height \: = 0.5 \times 5 \times 8 = 20
Hence, the total area of the four triangles is 4 × 20 = 80 cm^2.

Therefore, the total area of the pyramid is 80 + 25 = 105 cm^2. The answer is C.
