I'm not 100% sure but this is how I would try.
If you don't get a better answer, check this w/your teacher.
x/100 *90,000 = 1200
90,000x = 120,000
x = 1.3% tax percentage
1.3/100x = 2200
1.3x = 220,000
x = $169,230.77 assessed value
163.2 is the correct Answer
The first problem is true because with multiplication it doesn't matter which order it is in.
The second problem is false because you will get a different quotient depending on which numbers are on which side of the equation.
Answer:
2a - b = 5
Step-by-step explanation:
4a - 2b = 10
take out the highest common factor of the left side
2(2a - b) = 10
divide both sides by two
2a - b = 10/2
2a - b = 5
