Answer:

A.) 126°

Step-by-step explanation:

180-54=126

A straight line equals 180°

So you can subtract 180° by the known angle to find the unknown angle.

En una progresion geometrica el primer termino es 4 ¿ cual debe de ser la razon para que la suma de sus infinitos sea 5?
dem82 [27]

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

Solve independent system equations for: <br><br>5x-9y=-65<br>10x-3y=20<br>x=?<br>y=?<br>​
Sergio039 [100]
5x-9y=-65
10x-3y=20

Multiple the first equation by 2
10x-18y=-130
10x -3y=20
Then subtract the two equations to get rid of the x

21y=-150
Divide the -150 by 21
Y=-7.14

Plug the y into the original equation. (Either one)

5x-9(-7.14)=-65
5x-64.28=-65
Then add 64.28 to the -65
5x=-0.72
Divide by 5
X=-0.144

I hope this is right
