Answer:

334

(Pemdas rules apply)

Step-by-step explanation:

In order to sole this equation we must use what is called "PEMDAS" which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. This is also known as the order of operations which is the correct sequence of an equation (From left to right).

Now solving the equation itself:

4 [ 2.5 + 3 ( 20 + 7 ) ] <--- First add 20 and 7.

4 [ 2.5 + 3 ( 27 ) ] <--- Then multiply 27 by 3.

4 [ 2.5 + 81 ] <--- Then add 81 and 2 together.

4 [ 83.5 ] <--- Multiply 83.5 by 4.

= 334

Therefore, our final answer is 334, I hope this helps :)

Suppose 1 Bamboo Skewer Is About 30 Cm Long. How Many Skewers Would It Take To Make A Line 1 Million Centimeters Long?

Soloha48 [4]

(1,000,000 centimeters) x (1 skewer/30centimeters) =

 1,000,000 /30 skewers = 33,333 whole skewers,
 plus one piece of one more skewer
 cut into 3 equal pieces with the other
 two pieces discarded.

 Another way to look at it: 33,334 skewers,
with 2/3 of one of them not included.
