If you are trying to find the equation to this problem, I am pretty sure that it is 2x + x + 4 = 25.

First we must assign variables to the integers.

x = smallest
y = middle
z = largest

x + 7z = 68    ← This equation represents the given information
 
We can assume that "z" is less than 11 because 7*11 = 77, which is greater than 68.

Our possible consecutive odd integers could be:

a) 1, 3, 5
b) 3, 5, 7
c) 5,7, 9

Lets to plug in the "x" and "z" values

a) 1 + 7(5) = 1+ 35 = 36       This is incorrect, because 36 ≠ 68

b) 3 + 7(7) = 3 + 49 = 52      This is incorrect as well, because 52 ≠ 68

That leaves our final choice. Let's check to be certain

c) 5 + 7(9) = 5 + 63 = 68

5, 7, 9 is the 3 consecutive integers such that the sum of the smallest and 7 times the largest is 68.

A) ¿Qué nombre recibe la tabla?B) Elabore una distribución de frecuencias acumulativas y represente la distribución en un polí-g
Alex Ar [27]

Ok, primero haces estas hostilidades de considerable duración y magnitud. En el uso de las ciencias sociales, se agregan ciertas calificaciones. Los sociólogos suelen aplicar el término a tales conflictos sólo si se inician y conducen de acuerdo con formas socialmente reconocidas. Tratan la guerra como una institución reconocida en la costumbre o en la ley. Los escritores militares suelen limitar el término a las hostilidades en las que los grupos contendientes tienen el mismo poder para hacer que el resultado sea incierto durante un tiempo. Los conflictos armados de estados poderosos con pueblos aislados e impotentes suelen denominarse pacificaciones, expediciones militares o exploraciones; con los estados pequeños, se les llama intervenciones o represalias; y con grupos internos, rebeliones o insurrecciones. Tales incidentes, si la resistencia es lo suficientemente fuerte o prolongada, pueden alcanzar una magnitud que les dé derecho al nombre de "guerra".

Tyler used 1 1/2 gallons of paint to paint 5/7 of a fence. How many gallons will it take to paint the whole fence?
Mademuasel [1]

9514 1404 393

9514 1404 393

Answer:

  1) (1 1/2)(7/5) = g

  2) (1 1/2)/(5/7) = g

Step-by-step explanation:

1) Tyler has painted 5/7 of the 7/7 of the fence. So the total amount of the fence is (7/7)/(5/7) = 7/5 as much as what was already painted.

The total amount of paint needed is then 7/5 the amount already used:

  g = (7/5)(1 1/2) . . . . . gallons of paint needed for the whole fence

__

2) If g gallons are required for the whole fence, the amount used so far for 5/7 of the fence is 5/7 of the quantity required:

  (5/7)g = 1 1/2

  g = (1 1/2)/(5/7) . . . . division expression for the paint needed
