Select the correct answer. During the summer, Jody earns $10 per hour babysitting and $15 per hour doing yardwork. This week she worked 34 hours and earned $410. If x represents the number hours she babysat and y represents the number of hours she did yardwork, which system of equations models this situation? A. x + y = 34 10x + 15y = 410 B. x + y = 410 10x + 15y = 34 C. x + y = 34 15x + 10y = 410 D. x + y = 410 15x + 10y = 34

  A.  x + y = 34; 10x + 15y = 410

Step-by-step explanation:

Jody's total hours will be the sum of the hours spent on each job:

  x + y = 34 . . . . . total hours

Jody's total earnings will be the sum of the earnings from each job:

  10x +15y = 410 . . . total earnings

So, the system of equations is ...

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
