Answer:

x = 13

Step-by-step explanation:

3x + 12 + 5x + 16 + 4x + 18 = 202

combine like terms

12x + 12 + 16 + 18 = 202

12x + 46 = 202

-46 -46

12x = 156

divide by 12

x = 13

Add all the sides together (don´t forget parenthesis) Put the x´s with the x´s and the same with the other numbers. The subtract additional numbers from the total. The divide what left from the number in front of the x.

(3x + 12) + (5x + 16) + (4x + 18) = 202

8x + 28 + (4x + 18) = 202

12x + 46 = 202

- 46 -46

12x = 156

/12 /12

x = 13

LenKa [72]

Answer:

44,55,000 cubic meters of treasure could fit the pyramid.

Step-by-step explanation:

We are given the following in the question:

Base measure = 450 meters

Height = 66 meters

The volume of the pyramid is given by:

$V = \dfrac{AH}{3}$

where A is the ares of the base and H is the height of the pyramid.

Putting values, we get,

$V = \dfrac{1}{3}\times (450\times 450) \times 66\\\\V = 4455000\text{ cubic meters}$

Thus, 4455000 cubic meters of treasure could fit the pyramid.
