Question
abdel has $12 to spend on beans and rice.
. beans, b, cost $5 per pound.
. rice, r, costs $2 per pound.
abdel wrote 5b + 2r = 12 to represent this relationship.
use the equation to complete the table.
beans (lbs), b | rice (lbs), r
2 | 1
0.6 | 4.5
b | 0
Response
Explicación:
Paso1: Sustituir r = 0 en la ecuación
Dada la ecuación $5b + 2r=12$, sustituimos $r = 0$:
$5b+2(0)=12$
Paso2: Resolver para b
$5b=12$, entonces $b=\frac{12}{5}=2.4$
Respuesta:
2.4
