Answer:
True because 1/2 an hour is 30 minutes.
Step-by-step explanation:
Step-by-step explanation:


To solve a system of equations, we can add the two equations and solve for one of the remaining variables -- let's try to eliminate the
variable when we add the two equations together.
Right now, there's a
term in the first equation, and a
term in the second equation, so if we add those together, we'll be able to eliminate the
variable altogether and solve for
.
However, when we also have a
term in the first equation and
term in the second equation, so adding these together will also eliminate the
term, leaving a
on the left-hand side of the equation.
If we add the two numbers on the right side of the equation, we get
, which does not equal
, meaning there are no solutions to this system of equations.
#include <stdio.h> #include <stdlib.h>
// Function to perform division (x / y) of two numbers x and y. // without using division operator in the code. int divide(int x, int y)
{ // handle divisibility by 0. if (y == 0)
{ printf("Error!! Divisible by 0"); exit(1);
} // store sign of the result.
int sign = 1; if (x * y < 0)
