Answer:
mathematics make our brain fast and sharp
Step-by-step explanation:
According to this description we need a number that can be divided by 2,3 and 4 since the amount of rocks can be described by a natural number. However if a number is divided by 4 it is divided by 2 as well since 2*2=4.

If α is a natural number then 2*α is a natural number as well as the product of two natural numbers.
Which means that we need a number devided by 3 and 4.
The smallest number that fulfills this demand is 3*4=12.
Also any product of 12 with any natural number can be devided by 3, 4 and 2.
If the exercise asks for the numbers that are divided only by 2,3 and 4 these are:

Answer:
x = 3
Step-by-step explanation:
The translation rule (x + 10, y - 6) means add 10 to the original x- coordinate and subtract 6 from the original y- coordinate, that is
G(- 7, 4) → G'(- 7 + 10, 4 - 6) → G'(3, - 2)

Step-by-step explanation:
Answer:
67
Step-by-step explanation:
0.71=71%.
2/100+2/100=4/100/4%
So we can subtract 71-4=67.
That tells us that the missing number is 67. Add it all up and you will get 0.71 or 71%
