Respuesta:
La proporción común del término puede ser 1/5
Explicación paso a paso:
La fórmula para calcular la suma al infinito de una secuencia geométrica se expresa como:
Sinfty = a / 1-r
Dado
Sinfty = 5
Primer término a = 4
Requerido
Razón común r
Sustituir
5 = 4/1-r
5 (1-r) = 4
5-5r = 4
-5r = 4-5
-5r = -1
r = 1/5
Esto significa que la razón común debe ser 1/5 para que la suma hasta el infinito sea 5
A transversal is a line that intersects two or more other lines. When it intersects parallel lines, many angles are congruent. Parallel lines<span> are two </span>lines<span> that are always the same distance apart and never touch.</span>

1.06g + -3 = 0.71
Reorder the terms:
-3 + 1.06g = 0.71
Solving
-3 + 1.06g = 0.71
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 1.06g = 0.71 + 3
Combine like terms: -3 + 3 = 0
0 + 1.06g = 0.71 + 3
1.06g = 0.71 + 3
Combine like terms: 0.71 + 3 = 3.71
1.06g = 3.71
Divide each side by '1.06'.
g = 3.5
Simplifying
g = 3.5</span>
$25a + $15s =$305
a + s = 17
a = 17 - s
$25a +$15s =$305
$25(17-s) + $15s=$305
425-25s +15s = $305
425-10s=305
-10s=305-425
-10s= -120
-10s/-10 = -120/-10
s = 12
a+ 12 = 17
a = 5
Check
$25a + $15s =$305
$25(5) + $15(12) =$305
125 + 180 = 305
305 = 305
