= 2.5 ft.
Answer:
The larger number is 96.
Step-by-step explanation:
![let \: the \: two \: numbers \: be \: a \: and \: b \\ a + b = 110 \\ let \: a \: be \: the \: larger \: number \\ a = 7b - 2 \\ we \: can \: get \: the \: value \: of \: b \: by \: substituting \: the \: value \: above \: for \: a \: in \: eq \: 1 \\ 7b - 2 + b = 110 \\ 8b - 2 = 110 \\ 8b = 110 + 2 \\ 8b = 112 \\ b = \frac{112}{8} \\b = 14\\ calculate \:the \: value \: of \: a \: using \: the \: equation \: above \\ a + b = 110 \\ a = 110 - 14 \\ a = 96 \\ hence \: the \: large \: number \: is \: 96](https://tex.z-dn.net/?f=let%20%5C%3A%20the%20%5C%3A%20two%20%5C%3A%20numbers%20%5C%3A%20be%20%5C%3A%20a%20%5C%3A%20and%20%5C%3A%20b%20%5C%5C%20a%20%2B%20b%20%3D%20110%20%5C%5C%20let%20%5C%3A%20a%20%5C%3A%20be%20%5C%3A%20the%20%5C%3A%20larger%20%5C%3A%20number%20%5C%5C%20a%20%3D%207b%20-%202%20%5C%5C%20we%20%5C%3A%20can%20%5C%3A%20get%20%5C%3A%20the%20%5C%3A%20value%20%5C%3A%20of%20%5C%3A%20b%20%5C%3A%20by%20%5C%3A%20substituting%20%5C%3A%20the%20%5C%3A%20value%20%5C%3A%20above%20%5C%3A%20for%20%5C%3A%20a%20%5C%3A%20in%20%5C%3A%20eq%20%5C%3A%201%20%5C%5C%207b%20-%202%20%2B%20b%20%3D%20110%20%5C%5C%208b%20-%202%20%3D%20110%20%5C%5C%208b%20%3D%20110%20%2B%202%20%5C%5C%208b%20%3D%20112%20%5C%5C%20b%20%3D%20%5Cfrac%7B112%7D%7B8%7D%20%20%5C%5Cb%20%3D%2014%5C%5C%20calculate%20%5C%3Athe%20%5C%3A%20value%20%5C%3A%20of%20%5C%3A%20a%20%5C%3A%20using%20%5C%3A%20the%20%5C%3A%20equation%20%5C%3A%20above%20%5C%5C%20a%20%2B%20b%20%3D%20110%20%5C%5C%20a%20%3D%20110%20-%2014%20%5C%5C%20a%20%3D%2096%20%5C%5C%20hence%20%5C%3A%20the%20%5C%3A%20large%20%5C%3A%20number%20%5C%3A%20is%20%5C%3A%2096)
Answer:
La familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.
Step-by-step explanation:
El costo del agua viene dado por:
(1)
Y cada persona de la familia de Trevor gasto en promedio 72 litros de agua. Si la familia tiene 6 integrantes (incluido Trevor) entonces:
(2)
Entonces, toda la familia usó 432 litros de agua en promedio en todo el mes.
Para saber el dinero total gastado por la familia debemos multiplicar la ecuación (1) y la ecuacion (2):
![C = \$0.20/L*432 L = \$86.4](https://tex.z-dn.net/?f=%20C%20%3D%20%5C%240.20%2FL%2A432%20L%20%3D%20%5C%2486.4%20)
Por lo tanto, la familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.
