1 is correct 
2 is correct 
3 is correct 
4 is correct 
5 is correct 
6 is correct 
7 is correct
8 is wrong it should be because you wouldn't add the  you would subtract it and the otehr number is a negative so it would be x=-26
9 is correct 
10 is correct 
13 is correct
14 I think is correct
I think 15 is incorrect because if he says one less than twice the number of last year then I think you first shoudl subtract 1 from 25 and then divide by 2 this would give you  17 packeges
and I think 16 is correct too..

Hope this helped

Infinitely many solutions.

Step-by-step explanation:

4(4x+3)=19x+9-3x+3

16x + 12 = 16x + 12

0 = 0, so it doesn't matter what x is.

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180
