Let the Distance between A and B be : C km
Given : The Man Travels from A to B at a Speed 4 km/h
⇒ The Man Travels 4 km in One Hour during his Journey from A to B
⇒ 
⇒ 
Given : The Man Travels from B to A at a Speed 6 km/h
⇒ The Man Travels 6 km in One Hour during his Journey from B to A
⇒ 
⇒ 
⇒ 
We know that One Hour contains 60 Minutes
⇒ The Total Time taken by Man = 
Given Total Time Taken by Man is 45 Minutes
⇒ 25C = 45
⇒ 
But the Total Distance Traveled by the Man is 2C
⇒ 2C = 2 × 1.8 = 3.6 km
⇒ The Total Distance Traveled by the Man is 3.6 km
Answer:
(-1, 4)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
10x + 6y = 14
-x - 6y = -23
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Add 2 equations together: 9x = -9
- Divide 9 on both sides: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: -x - 6y = -23
- Substitute in <em>x</em>: -(-1) - 6y = -23
- Multiply: 1 - 6y = -23
- Subtract 1 on both sides: -6y = -24
- Divide -6 on both sides: y = 4
Answer:
Z is 
Step-by-step explanation:
We can rewrite the equation as P+Prz = B
Next, we can subtract the equation from both sides to get Prz = B - P
Finally, we divide both sides by Pr to get our final answer.
I know this is old but they deleted my old answer even though it didn't break it any rules so i'm just going to rephrase what I said
