Answer:
Step-by-step explanation:
Given
Length of string = x inches
Required
Determine the length in yards
Represent the equivalent length with y
Such that
Divide x by 36 to get equivalent in yards
Hence, the equivalent in yards is 
135
with math any absolute number cant be negative so you just make it positive
Let's eliminate x. To achieve this, mult. the 2nd equation by 2, obtaining
-8x + 2y = 10. Now add this result to the first equation:
8x-2y= -10
-8x + 2y = 10
---------------------
0
The two equations actually represent the same line. Without an x- or a y-value, we cannot solve for the value of the other variable. There are infinitely many solutions.

Respuesta:
175 rad / s²
Explicación paso a paso:
Dado que :
Velocidad angular final = 350 rad / s
Tiempo empleado = 2 segundos
La aceleración angular, a =?
Recordar ; la aceleración angular es igual a la carga en velocidad angular con el tiempo
(velocidad final - Velocidad inicial) / tiempo empleado
Velocidad inicial = 0 rad / s
Aceleración angular = (350 - 0) / 2 = 350/2
= 175 rad / s²
