Doreen uses 13 apples for every two pies she bakes. How many apples will she use for 12 pies?

78 apples for 12 pies

Step-by-step explanation:

she makes 12 pies

6x2 = 12 pies

so we do 13x6

13x6=78

78 apples for 12 pies :)

can i get brainliest

13/2 = 6.5

12 x 6.5 = 78

? = 78

13/2 = 78/12

Step-by-step explanation:

13 apples ÷ 2 pies = 6.5 apples per pie

12 pies x 6.5 apples per pie = 78 apples for 12 pies

? = 78 apples for 12 pies

13/2 = 78/12

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
