Answer:
All in the explanation
Step-by-step explanation:
It would be a dollar for every mile traveled, in this case 10 dollars as Ms. Robinson travels 10 miles.
The starting cost would be 5 dollars to rent it and then 1 dollar for every mile.
Equation would be 1(x) + 5
The cost of Ms. Robinsons trip would be 1(10) + 5 = 15 dollars.
Answer:
Santosh purchased 4 new and 4 used DVDs.
Step-by-step explanation:
From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:
15x+5y=80, where:
x refers to the number of new DVDs
y refers to the number of used DVDs
Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:
15x+5x=80
20x=80
x=80/20
x=4
According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.
This should be the correct answer,
4.5×10^9x + 0.00045x
Also, some good free calculators that can help with problems like this would be c y m a t h and m a t h w a y .
let's say 12 min - 2 mins = 10 mins
and 1.4 mile - 0.9 miles = 0.5 miles
Jessica takes 10 mins to walk a distance of 0.5 miles
=> 10 mins*6 = 60 mins = 1 hour
=> 0.5 miles*6 = 3 miles
her rate is 3 miles per hour
