Question

5n+25>5500-8n+3501>210-5n

Answer 1

Explicação passo-a-passo:

$5n+25>5500-8n+3501>210-5n$

$5n+25>-8n+9001>210-5n$

resolvando o lado esquerdo

$5n+25>-8n+9001$

$5n+8n>9001-25$

$13n>8976$

$n>\frac{8976}{13}$

resolvendo o lado direito

$-8n+9001>210-5n$

$9001-210>-5n+8n$

$8791>3n$

$n<\frac{8791}{3}$

juntando fica

$\frac{8976}{13}<n<\frac{8791}{3}$
