To answer this question you basically have to add up day 1, day 2 and day three then take it away from 30 so.....
7.7+6.4+8.0=22.1
30-22.1=7.9 so they have 7.9 miles left to walk
Answer:

Step-by-step explanation:
using the Pythagorean theorem:
y² = 20² + 21² = 400 + 441 = 841
y = √841 = 29
-5,5 you are welcome:) good luck
A = -16
B = 25
C = 5
Plug into the quadratic equation and you get: -0.18 and 1.75. Since we cannot have a negative time our answer is 1.75 seconds.
Answer:
x = 18
Step-by-step explanation:
Given:
Finding x for which 3b = 5a:
- 3(4x - 7) = 5(2x + 3)
- 12x - 21 = 10x + 15
- 12x - 10x = 15 + 21
- 2x = 36
- x = 36/2
- x = 18
