Write an equation as part of solving the problem. The purchase price of a large 4K LED TV, including finance charges, was $1480.
Leto [7]

Answer:

$57.50

Step-by-step explanation:

1480 = 100 + 24x

1480 - 100 = 24x

1380 = 24x

x = 1380/24

x = $57.50, where x represents the monthly payments.

Mezclas de alimentos. Un chef repostero creó una solución de azúcar de 50 onzas constituida por 34% de azúcar con una solución d
Kay [80]

Answer:

Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

Step-by-step explanation:

Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:

0.34= \frac{0.2\cdot m_{A} + 0.4\cdot m_{B}}{m_{A}+m_{B}} (1)

Donde:

m_{A} - Masa de la solución al 20 %, en onzas.

m_{B} - Masa de la solución al 40 %, en onzas.

Podemos simplificar la formula como sigue:

0.2\cdot x + 0.4\cdot (1-x) = 0.34 (2)

Donde x es la proporción de la solución al 20 % dentro de la solución final, sin unidades.

Ahora resolvemos para x en (2):

0.4-0.2\cdot x = 0.34

0.2\cdot x = 0.06

x = \frac{0.06}{0.2}

x = 0.3

Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.

After which value of x does function g exceed function f
nalin [4]
We have that

for x=1
f(x)=1.5  and g(x)=-1
so
g(x) < f(x)

for x=2
f(x)=5  and g(x)=5
so
g(x)= f(x)

for x=3
f(x)=9.5  and g(x)=23
so
g(x) > f(x)

therefore

the answer is
<span>After x=2 function g exceeds function f</span>
