Answer:
8 hours
Step-by-step explanation:
Subtract the initial fee from the total cost
Divide the hourly rate by the cost after the fee
Joan rented the bike for 8 hours
(-2v-49)x(5v-100)
Multiply each term in the first parentheses by each term in the second parentheses (foil)
-2vx5v-2vx(-100)-49x5v-49 x (-100)
calculate the product
-10v²-2v x(-100)-49x5v-49 x(-100)
-2vx5v
Multiply the numbers
-10v x v
the same of the other one ok is different how i am doing
-2vx5v
If a term doesn't have an exponent , it is considered that the exponent is 1
-10v^ 1 x v
-10v^1 xv^1
Multiply the terms with the same base by adding their exponents
-10v^1 x v^1
-10v^1+1
to add the numbers using a number line, start from zero
1+1=2
Since 1 is positive, move the point 1 unit to the right
The result is 2
Answer: -10v^2
That's it . Hope it wasn't too hard to understand?

Answer:
Approximately 15 tea hees
Step-by-step explanation:
Given that:
Number of teachers needed to Mark 500 exam papers in 30 hours =
Hence, marking rate of each teachers ;
500 / (30 * 10) = 500 / 300 = 1.667 papers per hour
If teachers mark at this rate, the number of teachers which will be required to mark 600 exam papers in 25 hours ;
Let number of teachers = t
(Rate * number of hours * number of teachers) = number of exam papers to be marked
(1.6667 * 25 * t) = 600
41.666665t = 600
t = 600 / 41.666665
t = 14.40000
Number of teachers needed = about 15 teachers
Answer:
pages
Step-by-step explanation:
Method 1: Working with minutes
Let us assume that, Sandra's printer can print x pages in 1 minute.
Then we can write the equation:
We can rewrite the ratios as a fraction.
This simplifies to
Or
Method 2: Working with seconds
If 5 pages corresponds to 40 seconds, then we can write: 
Let y corresponds to 60 seconds (1 minutes).
Then:
We rewrite as fraction:
Multiply both sides by:
