For his long distance phone service, deandre pays a $7 monthly fee plus 7 cents per minute. last month, deandre's long distance bill was $15.47. for how many minutes was deandre billed?

Deandre was billed for 121 minutes.

Step-by-step explanation:

Let x represent the number of minutes for which Deandre was billed in a month.

For his long distance phone service, Deandre pays a $7 monthly fee plus 7 cents per minute. Converting 7 cents to dollars, it becomes

7/100 = $0.07

If he made x minutes of distance call in a month, his total cost would be

0.07x + 7

Last month, Deandre's long distance bill was $15.47. It means that

0.07x + 7 = 15.47

0.07x = 15.47 - 7

0.07x = 8.47

x = 8.47/0.07

x = 121

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
