Step-by-step explanation:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.
Answer:
that is invalid question
Step-by-step explanation:
We have that
n----------> number of cities
the probability that the tourist will visit the cities in alphabetical order is (1/n<span>!)
P=</span>(1/n!)
n!-------------> (7*6*5*4*3*2*1)=5040
therefore
1/5040=0.000198-----------> (five decimal places)--------> 0.00020 (0.020%)
the answer is 0.00020 (0.020%)
Answer: x = -11
Step-by-step explanation:
Expand the expression (distributive property): 3 - 9x = -8x + 14
// subtract 14 from both sides = -11
// add 9x on both sides = x
Simplify: x = -11
You need to find "dollars per hour". So you need to know the total dollars and the total hours.
You already know the total dollars ... it's 54.
What are the total hours ? 2-1/2 plus 4-1/4 . Can you add those ?
Once you add up the total hours, divide ($54) divided by (total hours).
The quotient is the number of dollars she earns for each hour she works.
