Use the elimination method to solve the system of equations. Choose the correct ordered pair. 3x-4y=-36 10x+2y=64 A. (4, 12) B. (2, 10) C. (-5, 8) D. (-3, 11)​

The answer is C          

3/10

Step-by-step explanation:

Since the rest of the trees are pears trees and plum trees in the ratio of 7:5 and there are 175 plum trees, the number of pear trees will be:

= 175 ÷ 5/7

= 175 × 7/5

= 245

Plum trees = 175

Pear trees = 245

Apple trees = 600 - (175 + 245)

= 600 - 420

= 180

Fraction of apple trees = Number of apple trees / Total number of trees

= 180/600

= 3/10
