Answer:
Smallest integer: 20
Middle integer: 22
Largest integer: 24
Step-by-step explanation:
Denote the smallest integer as "x"; hence the next integer will be "x + 2", and the third will be "x + 4".
Using the information, set up an equation:
x + x + 2 + x + 4 = 66
Simplify
x + x + 2 + x + 4 = 66
3x + 6 = 66
Inverse operations
3x + 6 = 66
-6 -6
3x = 60
/3 /3
x = 20
Smallest integer: 20

Suppose that you need to buy some chicken for dinner tonight. You found an ad showing that a store across town has chicken on sale for $2.99 per pound. Your usual neighborhood store sells the same chicken for $3.79 per pound. You are considering whether it is worth the drive to purchase the chicken from the store across town. Information you will need:________
A. You need to purchase 3 pounds of chicken
B. Your neighborhood store is 2.1 miles away and takes about 8 minutes to get there
C. The store across town is 8.6 miles away and takes about 24 minutes to get there
D. Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon
Answer:
C). The store across town is 8.6 miles away and takes about 24 minutes to get there.
D). Your car averages about 22 miles per gallon in the city Gas is $3.05 per gallon.
Step-by-step explanation:
The information regarding the distance of the store across town from the house, the time required to reach there, the average of the car, and the cost of gas per gallon would assist in calculating if the extra drive is worth buying chicken from the city store.
Cost of chicken in the city store - $2.99 per pound
Average of the car in 1 gallon = 22miles
so, the average of the car in 1 mile = 1/22
Cost of traveling 8.6miles = 8/22 * $3.05
= 24.40/22
Additional cost = $ 1.109
Total cost of buying chicken from the city store = $2.99 + $1.10
= $4.09
Hence, it is not worth to buy the chicken from the store across the town as it is costlier in comparison to $3.79 in nearby store.

Anyone know the answer?
Answer:7
Step-by-step explanation: The range is the value of the difference of the highest and lowest numbers. As I can see here, the highest is 9, while the lowest is 2, so 9-2=7
THE DIFFERENCE OF TWO NUMBERS IS 17. IF THE GREATER NUMBER IS 32, FIND THE SMALLER ONE. (STEP BY STEP)
difference means subtracting. if thr greater number is 32 then what minus 32 equals 17? 32-15=17
Answer:
15
Step-by-step explanation:
think the number is x

En la casa de la familia de Trevor viven 6 personas (incluyendo a Trevor) y hay 3 baños. En el último mes, cada
persona se bañó durante un promedio de 480 minutos y utilizó un promedio de 72 litros de agua al bañarse
(en todo el mes). El agua cuesta 0.20 dólares por litro.
¿Cuánto dinero gastó la familia de Trevor en total en agua al bañarse el mes pasado?
dólares.
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:
[tex] C = \$0.20/L [/tex] (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:
[tex] A = 72 L*6 = 432 L [/tex] (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):
[tex] C = \$0.20/L*432 L = \$86.4 [/tex]
Por lo tanto, la familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.
Espero que te sea de utilidad!
Usando proporciones, hay que la familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.
En la casa, hay 6 personas.Cada persona utilizó un promedio de 72 litros de agua.Por eso, en todo, 6 x 72 = 432 litros de agua fueron usados.
Cada litro cuesta $0.2. De esa forma, el total de dinero gasto es de:
T = 0.2 x 432 = 86.4.La familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.
