Answer:
23 minutes
Step-by-step explanation:
First, take away $26.09 from $30. This will show you how much was spent on the call. You should get $3.91.
Next, it may be easier to convert this total all to cents. So 100 cents in every dollar...100 cents times 3 = 300 cents. Then add the other 91 cents to get a total of 391 cents.
Then, you need to divide 391 cents by 17 to get the minutes. And you'll get 23 minutes!
Answer:
x > 3
Step-by-step explanation:
This is based on the concept 'when a negative number is multiplied to both sides of the inequality, the sign gets reversed. For example, x > - 2 when it is multiplied by - 1, it becomes - x < 2.'
*only when the number is -ve.
Similarly, in this question, multiply both sides by - 1.
2x > 6
x > 6/2
x > 3
For more : take - 5 > - 2, as you know
Note that 5 is actually greater than 2. To make this true we change signs
