Answer:

46 minutes

Step-by-step explanation:

Sorry about not answering your question sooner, but here is your answer:

In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:

15 - 6.72 = 8.28

Then, we divide this number by 0.18:

8.28 / 0.18 = 46

So, Tammy's call lasted 46 minutes

Hope this helps :)

The measure of the supplement of an angle is 84° less than the measure of the angle. Find the measures of the angles
babunello [35]

Let the measure of angle be 'x'

Since, the measure of the supplement of an angle is 84° less than the measure of the angle.

Therefore, measure of supplement of x = x - 84°

The measure of two supplementary angles is 180 degrees.

x + x -84^\circ = 180^\circ

2x -84^\circ = 180^\circ

2x =84^\circ + 180^\circ

2x =264^\circ

x =132^\circ

So, the measure of angle =x =132^\circ

Its supplement = x - 84°  = 132°  - 84°

=  48°

So, the measure of supplement of angle is 48 degrees.
