For the equation:
4x+(5x+3)=9x+3
The property is
Commutative property of Addition
For the equation:
a+b=b+a
The property is
Associative Property of Addition
Answer:
4,500
Step-by-step explanation:
To find the number of students majoring in economics, you must turn 90% into a decimal making it .9.
Then you multiply the decimal to how many students there are (5000x.9) and that gives you 4,500.
The answer is 63. Just plug the answers in for the variables. As my math teacher always says, “just plug and chug!”
Answer: 8.8
Step-by-step explanation:
Because 
by the reflexive property, we know that 
by AA.
So, by the triangle proportionality theorem,
