Consider the given monomials. Let us determine the sum of these monomials,
1. 
= 
Therefore, the sum of the given monomials is
.
2. 
= 
= 
Therefore, the sum of the given monomials is
.
3. 
= 
Therefore, the sum of the given monomials is
.
4. 
= 
= 
Therefore, the sum of the given monomials is
.
First you do $33.00/4 to get $8.25. Take the 8.25 and multiply it by 7 to get $57.75
The answer is 18. It says that Trina scored 6 less than Rachel and Trina scored 12. Add 12 and 6 and get 18. Rachel scored 18 points
Just substitute in the numbers:
7j+5-8k
=7(0.5) + 5 - 8(0.25)
=3.5 + 5 - 2
=6.5
