10 and 15 dear^^ 5(15) + 3(15) =28
So,
The range will simply be the absolute value of the difference between the highest and lowest price.
The highest price is $2285.
The lowest price is $1116.
The absolute value of the difference between these two prices is:
|2285 - 1116| = 1169
The range of the prices for the gold phone is $1169.
Answer:
average speed = (55 + 70 + 525) / 6
= 650 / 6
= 108.33 km per hour
Step-by-step explanation:
first hour = 55 per hour.
= 55
second and third = 35 per hour.
= 70
fourth, fifth and sixth = 175 per hour.
= 525
average speed = (55 + 70 + 525) / 6
= 650 / 6
= 108.33 km per hour
Answer: 
Step-by-step explanation:
To solve this problem, we want to make sure the denominators are the same on both fractions. Once they are equal, we can dd them together.
[multiply first fraction by y+4 and second by y-8]
[distribute by FOIL]
[add numerator]
[combine like terms]
[factor out 2 from numerator]
Now we know that is the factored form after adding.
Answer:
the trip for each person will cost $50
Step-by-step explanation:
the total cost of the trip is 200 and there are 4 people, so if we divide 200 by 4 we will get the value of what it costs each person
200/4 = 50
to verify that it is correct what we can do is add 4 times the value of 50 that would be what it cost each person
50 + 50 + 50 + 50 =
100 + 50 + 50
150 + 50
200
this means that the result is correct
