Answer:
Step-by-step explanation:
separate with like terms
the first fraction can be left alone as it can't be simplified any further
the second fraction can be written as w⁹ ÷ w¹ , when the bases are the same and division is involved subtract the powers: 9 - 1 = 8, so it's simplified to w⁸
the third fraction can be written as m⁵ ÷ m⁹, subtract the powers: 5 - 9 = -4, so it's simplified to m⁻⁴

No portion of your medical expenses you can deduct
Step-by-step explanation:
You discovered you can deduct medical expenses over 6% of
your income
Your income is $42,000
You had medical expenses of $567
We need to find the portion of your medical expenses you can deduct
∵ Your income = $42,000
∵ You can deduct medical expenses over 6% of your income
- Find the 6% for your income
∵ 6% of the income = × 42,000 = $2520
∴ 6% of your income is $2520
∵ You can deduct medical expenses over 6% of your income
∴ If your medical expenses greater than $2520, then you can
deduct the value greater than it, but if your medical expenses
smaller than $2520, then you can not deduct any value
∵ You had medical expenses of $567
∵ $567 < $2520
∴ There is no value you can deduct from your medical expenses
No portion of your medical expenses you can deduct
