whats the question?
Step-by-step explanation:
There were 170 adults and 140 children.
<span>Podemos resolver as equações da seguinte forma:
11) -2,6 x 10³ ----> iremos andar três casas para direita.
X = -2600 12) 5,824 x </span>
![10^{-2}](https://tex.z-dn.net/?f=%2010%5E%7B-2%7D%20)
<span> ---> iremos andar duas casas para esquerda.
X = 0,05824 13) - 5,408 ---> iremos adicionar o </span>
![10^{0}](https://tex.z-dn.net/?f=%2010%5E%7B0%7D%20)
<span>
x = </span>
- 5,408 x ![10^{0}](https://tex.z-dn.net/?f=%2010%5E%7B0%7D%20)
<span>
14) 0,00907 ----> iremos adicionar o </span>
x = 9,07 x
Espero ter ajudado :)
20,000 + 5,000 + 300 + 2 = 25302
25,302 x 1 = 25,302
24,000 + 1302 = 25302
25,000 + 302 = 25302
