Answer:
Step-by-step explanation:
Step 1:
Step 2:
Step 3:
Step 4:
To complete the square, add 
to both sides.
Step 5:
Step 6:
Taking square roots on both sides.
Reducing
9x + -31 = 43
Rearranging the components:
-31 + 9x = 43
Finding the solution
-31 + 9x = 43
Isolating the variable 'x'.
Shift all terms with x to one side,
Add '31' to both sides of the equation.
0 + 31 + 9x = 43 + 31
Summing up similar items:
-31 + 31 = 0
0 + 9x = 43 + 31
9x = 43 + 31
Summing similar items:
43 + 31 = 74
9x = 74
Split each side by '9'
x = 8.222222222
Simplifying
x = 8.222222222
Answer:
45 millas.
Explicación paso a paso:
Dado que la:
Distancia total recorrida = 390 millas
Tiempo total = 8 horas
Designando la distancia recorrida por la vía local como L
y la distancia recorrida por la carretera como H
Por la vía local,
La Velocidad = distancia/ tiempo
20 = L / T
T = L /20.... (1)
Por la carretera,
Distancia recorrida H = 390 - L
Sea el tiempo = t
La Velocidad = distancia/tiempo
60 = (390 - L)/t
t = ( 390 - L)/60
Pero el tiempo total = T + t
<pEs decir
8 = L/20 + (390 - L)/60
<pEl MCM en el lado derecho sería 60<p8 = ( 3L + 390 - L )/60<pMultiplicamos en cruz
480 = 2L + 390
<pAgrupamos los términos semejantes
2L = 480 - 390
2L = 90
L = 90/2
L = 45 millas.
<pAsí que la distancia que Minato recorrió por vías locales es de 45 millas
To determine the number of bags, we simply compute the quotient, which yields:
(12 / 15 pounds) / (1 / 3 pounds) = 2.4 bags
Since bags can't be represented in decimals, only 2 bags can be filled. The remainder is 0.4 which can be expressed as:
0.4 * (1/3) = (2/5) * (1/3) = 2/15 pounds
Answer:
<span>2 bags are filled, with 2/15 pounds of granola remaining</span>
