Answer:
its B
Step-by-step explanation:
The first step to solving this would be to determine how many miles are represented by 1 inch:
15/2.5 = 6
1 inch = 6 miles
Now we want to know how far 4 inches is in miles:
6*4 = 24
Greenwood and Bay City are 24 miles apart
Hope this helps (also please mark me brainliest I only need 1 more to rank up)
Answer:
- you - 4 rocks and 16 fossils
- friend - 12 rocks and 8 fossils
Step-by-step explanation:
Let the rock be r and the fossil be f
<u>Equations</u>
- You: r + f = 20
- Friend: 3r + 1/2f = 20
<u>Double the second equation and subtract the first one:</u>
- 2(3r + 1/2f) - (r - f) = 2*20 - 20
- 6r - r = 20
- 5r = 20
- r = 4
<u>Then find f:</u>
So you collect 4 rocks and 16 fossils
<u>Friend collects:</u>
- 4*3 = 12 rocks and
- 1/2*16 = 8 fossils
Divide total miles by total days:
25.5 miles / 5 days = 5.1 miles per day.
Answer:
Step-by-step explanation:
Factor top and bottom.
The numerator is a difference of two squares, and the denominator is a quadratic.
