To solve this problem, you can create a system of equations and solve for each hiker's distance walked.
Hiker 1 distance walked: x
Hiker 2 distance walked: y
Their combined distance walked is 53 miles, thus -
x + y = 53
The difference between miles walked is 25, thus -
x - 25 = y
Let's solve using substitution. To do that, substitute x - 23 into x + y = 53 for y.
x + y = 53
x + (x - 25) = 53
x + x - 25 = 53
2x - 25 = 53
2x = 78
x = 39
To find y, substitute 39 for x into either of the equations.
x + y = 53
39 + y = 53
y = 14
Finally, check all work.
x + y = 53
39 + 14 = 53
53 = 53
x - 25 = y
39 - 25 = 14
14 = 14
Answer:
One hiker walked 39 miles and the other hiker walked 14 miles.
10x-2y=10 We need to solve this equation for "y" to put it into slope intercept form:
10x-2y=10
-2y = -10x +10 Subtracted 10x from both sides
y = 5x - 5 Divided both sides by -2
y = 5x - 5 Is slope intercept form
Answer:
Step-by-step explanation:
- Two triangular ends
- Area of one = 1/2 b * h
- b =1.2
- h =0.9
- Area = 1/2 * 1.2 * 0.9 = 0.54 sq meters
- Area of 2 = 2 * 0.54 1.08
Area bottom
- L = 3.5 m
- w = 1.2
- Area = L * W
- Area = 3.5 * 1.2
- Area = 4.2
Area Back
- L = 3.5
- W = 0.9
- Area = 3.5 * 0.9
- Area = 3.15
Area Slanted piece
- L = 3.5
- w = 1.5
- Area = L * W
- Area = 3.5 * 1.5 = <u> 5.25</u>
Total = 5.25 + 3.15 + 4.2 + 1.08 = 13.68
Answer:
A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. A law is a statement about an observed phenomenon or a unifying concept, according to Kennesaw State University. ... However, Newton's law doesn't explain what gravity is, or how it works.
