Ill assume it is :-

tan^2 A - 2 tan A + 1 = 0
(tan A - 1)^2  = 0
tan A = 1

m < A  =  45,  225 degrees   ( where  0  <  m A < 360 )

Josh sold 465 bottles of apple cider and 605 bottles of wine. He made $10,050 altogether. If he sold 465 bottles of apple cider
Anon25 [30]

Answer:

465a + 605w = $10050

465a + 586w = 9822

465a + 605w = 10050

-465a - 586w = -9822

19w = 228

w= $12 each for wine

465a + 605(12)= 10050

465a + 7260= 10050

465a = 2790

a =$6 each apple cider

7d + d - 4d - 7 = 5d

8d - 4d - 7 = 5d

4d - 7 = 5d

5d = 4d - 7

Subtract sides 4d

- 4d + 5d =  - 4d + 4d - 7

d =  - 7

Thus the correct answer is Option three.
