In a school, 15% of students speak two languages. If 145 students speak two languages, what is the total number of students, s, in the school?

there is about 966 or 967

Step-by-step explanation:

145 ÷ .15 = 966.66 repeating

then to check my answer I did my answer times .15 to see if I get 145 and I did

hoped that helped

966 or 967

Step-by-step explanation:

15%=145

divide by 3

5%=48.33333

times by 20

100%=966.6666

so there is either 966 students in the school or 967

this is unclear

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
