Responder:
24 litros; 16 litros; 4 litros
Explicación paso a paso:
Dado que:
Gasolina consumida = 20 litros
Sea la cantidad de gasolina en el tanque = x
Primera parte del viaje = 2/3 de x
Segunda parte del viaje = 1/2 de (x - 2x / 3)
Cantidad de gasolina en el tanque:
2x / 3 + 1/2 (x - 2x / 3) = 20
Solución para x
2x / 3 + x / 2 - x / 3 = 20
(4x + 3x - 2x) / 6 = 20
5 veces / 6 = 20
5 veces = 20 * 6
5 veces = 120
x = 120/5
x = 24
Cantidad de gasolina en el tanque = 24 litros
Litros consumidos en cada etapa:
Primera parte = 2/3 de 24 = 48/3 = 16 litros
2a parte = 0.5 de (24 - 16) = 0.5 * 8 = 4 litros
1) he is not reasonable because pounds per feet would mean you would do 7.3/14.6 which is a decimal
hope this helped :)

Answer:
61 - 10x
2k
42 / 6 = 7
38 + 2m
3y - 6
Step-by-step explanation:
A. Sixty-one diminished by ten x
= 61 - 10x
B. The product of twice a number k
= 2 * k
= 2k
C. The quotient of forty-two and six is seven
42 / 6 = 7
D. Twice the total of nineteen and a number m.
= 2(19 + m)
= 38 + 2m
E. Six less than 3 times y
3y - 6
Answer:
A. 12.5 miles per hour B. 0.36 hours
Step-by-step explanation:
3.75/.30=12.5 , so divide 3.75 by the time 0.30 hours and you get your miles per hour
next, take 4.5 and divide by the new mph 12.5 from your previous answer.
4.5/12.5=0.36 hours
