Me with all three and explain it for brainiest and extra points! me i don’t get it

Problem 16

Divide both sides by 2 to undo the multiplication of 2 (done to the t). 

2t > 324
2t/2 > 324/2
t > 162

t > 162



Problem 17

Similar to problem 16, we will divide both sides by 12

12y >= 1
12y/12 >= 1/12
y >= 1/12

y >= 1/12

Note: the symbol ">=" without quotes means "greater than or equal to". 



Problem 18

To undo the division of 9.5, we multiply both sides by 9.5

x/9.5 < 11
9.5*x/9.5 < 9.5*11
x < 104.5

x < 104.5

There is not enough information on this sorry can you take a picture of it and put it on here
