The inequality that represents the possible combinations of candy bars and lollipops that he can buy is given by:

<h3>What is the inequality that models this situation?</h3>
The total price can be no more than $28, hence:

Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:
T = 0.45x + 0.25y.
Hence, the inequality that models the situation is:

5*(60+3)
You should write 63 in this way 60+3


Take HJ = a, GH = b and GJ = c
put the value of a from equation 1 in equation 2
now, put the value of a and c in equation 3
Now, we need to find HJ (a)

Answer: 
Step-by-step explanation:
To solve this exercise you need to remember the following properties:
1. The Distributive property states that:

2. The Addition property of Equality statest that:
If
, then 
3. The Subtraction property of Equality statest that:
If
, then 
4. The Division property of Equality statest that:
If
, then 
5. The Multiplication property of Equality statest that:
If
, then 
Given the equation:

You must solve for "g" in order to find its value:
- Apply the Distributive property:

- Apply the Addition property of Equality adding 30 to both sides of the equation:

- Apply the Division property of Equality dividing both sides by 2:
