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

Answer: t > 162

=====================================================

Problem 17

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

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

Answer: 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

Answer: x < 104.5

Mrs.jackson bought 7 dozen eggs if each student is given the same out of eggs how many eggs are left
nikdorinn [45]
Without knowing the number of students she has, you will not be able to answer the question correctly. There are 12 eggs in one dozen. 12 x 7 dozen = 84 eggs. You still need to know the number of students.
