Question

Salut am nevoie de aceste exercitiu urgent va rog dau coroana ​

Answer 1

x= distanta

prima zi: 30/100•x= 3x/10

a doua zi: 14 km

x= 3x/10+14 |•10

10x=3x+140

7x=140=>x=20 km

Answer 2

Răspuns:

30x/100=3x/10 parcurge in prima zi

3x/10+¹⁰⁾14=¹⁰⁾x

3x+140=10x

140=10x-3x

x=140:7

x=20 km are drumul

verificare:

30·20:100=6 km a parcurs in prima zi

6+14=20 km are drumul
