TRABAJO DE MATEMATICAS. ECUACIONES
INSTRUCCIONES: resolver los siguientes problemas a través del uso de
ecuaciones de primer grado
1. Ocho veces un número aumentado en 30 es igual a seis veces el mismo
número aumentado en 50
2. La suma de tres números enteros consecutivos es 84. ¿cuáles son esos
números?
3. El perímetro del siguiente rectángulo es igual a 36cm, si la base equivale al
doble de la altura aumentado en 3, cuánto vale en un número real la base y
la altura
---------------------
l ,,,,,,,,,,,,,,,,,,,,,,,,, l -- este es el rectángulo
---------------------
4. 6(a+5)= 42
Respuestas
Respuesta:
1. 8x + 30 = 6x + 50
=> 2x = 20 => x = 10
2. (x-1) + x + (x+1) = 84
=> 3x = 84 => x = 28
3. altura = x base = 2x + 3
=> Perímetro= 2(x + 2x + 3) = 6x + 6 = 36
=> 6x = 30 => x = 5
altura = 5 y base = 13
4. 6(a + 5) = 42
=> 6a + 30 = 42 => 6a = 12 => a = 2
