Answer: -63

Step-by-Step Solution:

=> an = 3 - 6(n - 1)

Hence,
=> a = 3
=> d = -6
=> n = 12

Therefore,
an = 3 - 6(n - 1)
a12 = 3 - 6(12 - 1)
a12 = 3 - 6(11)
a12 = 3 - 66
=> a12 = -63

3x - 3 = 12

3x - 3 + 3 = 12 + 3

larisa86 [58]

Hey there! I'm happy to help!

How many times does 20 go into 48?

48/20=2.4

So, we multiply our amount of flour for 20 cookies by 2.4.

2.25×2.4=5.4

Therefore you would need 5.4 or 5 2/5 cups of flour to make 48 cookies.

Have a wonderful day! :D
