Answer:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
Build time (hours) = 4c + 6a = 120
Test time (hours) = 4c + 4 a = 100
Where c represents the number of child bikes and a represents adult bikes.
So, for 20 child bikes and 6 adult bikes:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100

Responder:
$ 3720
Explicación paso a paso:
Dado que:
Tasa mensual, r = 8%
Principal, P = $ 3000
Duración o período, t = 3 meses
La cantidad final, A, que pagará después de 3 meses:
Usando la fórmula de interés simple:
A = P (1 + rt)
A = 3000 (1 + 0,08 * 3)
A = 3000 (1 + 0,24)
A = 3000 (1,24)
A = $ 3720
It would be 24 to 12 and when implied the answer is A 2 to 1
2.7 gallons.
Since the tank is already 4/5 full, only 1/5 is needed to fill it completely. As 13.5 gallons represent 5/5 (the full tank), you can take 13.5 divided by 5 to find 1/5.
