Step-by-step explanation: 1/3 of 18 is 6. 1/3=33.3% it moved down by six people so 33% is your answer
Answer:
x = 6
Step-by-step explanation:
Step 1: Write equation
150 - x - 2x = 120 + 2x
Step 2: Solve for <em>x</em>
- Combine like terms: 150 - 3x = 120 + 2x
- Add 3x to both sides: 150 = 120 + 5x
- Subtract 120 on both sides: 30 = 5x
- Divide both sides by 5: 6 = x
- Rewrite: x = 6
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
150 - 6 - 2(6) = 120 + 2(6)
144 - 12 = 120 + 12
132 = 132
Answer:
24$
Step-by-step explanation:
its just 9$ + 15$ = 24$
Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.
Whole numbers is the correct answer
