C is correct. You have to pay attention to the corresponding sequences of the vertices. C is correct because in the three triangles, MON, MPO, OPN are the right angles, respectively. However, the angles are not consistent in other given choices.
Gabrielle is x years old.
Felicia is 6 years older.....so Felicia is x + 6
the mom is twice as old as felicia...so the mom is 2(x + 6)
the aunt is x years older then mom....so the aunt (tanya) is 2(x + 6) + x
so Tanya/s age is :
2(x + 6) + x =
2x + 12 + x =
13x + 12 <===
Mathematical models are helpful. Advantages include helping you see the data clearer and helping you visualize. Disadvantages are: time consuming, and if you make a mistake on the graph, its going to hit the entre thing.
tax gets added to the price of the camera
so the equation is:
x + 0.07x = 45; x = $42.06
