Mrs. Lopez joins the local gym and pays $50 per month. Each exercise class is an
additional $10. If her bill for the gym last month was $120, how many
exercise classes did she attend? c = the number of classes *

Choose the equation that matches this real world problem.

1) 10c-50=120
2) 50c-10=120
3) 10c+50=120
4) 120+10c=50

there is no grid

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
