It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.
Answer:
The cost of parts was $65.
Step-by-step explanation:
Let the cost of parts = x
35 + 21(3) + 1.10x = 169.50
98 + 1.10x = 169.50
71.50 = 1.10x
71.50/1.10 = 65

Answer:
Yes, it costs $18.99.
Step-by-step explanation:
The game is originally $36 and a game 50% off is 36/2 = $18.
The sale price is $18.
The state charges 5.5% tax which means you pay 105.5% of the sale price.
1.055(18) = 18.99
The final total is 18.99 which means Ron's $19 is enough.
