Answer:
The answer to your question is Katie had 15 rocks and Oliver 45 rocks.
Step-by-step explanation:
Conditions
Katie has x amount of rocks
Oliver has 3x amount of rocks
The final amount of rocks
Oliver = 3x + 75
Katie = x + 105
Now, they have the same amount of rocks, then we can equal both equations
3x + 75 = x + 105
Solve for x
3x - x = 105 - 75
2x = 30
x = 30/2
x = 15
Conclusions
At first Katie had 15 rocks and Oliver had 3(15) = 45 rocks
Answer:
$6.37
Step-by-step explanation:
Jane and 3 friends = Jane + another 3 people
= 4 people in total
Total Cost of pizza = $25.48
If 4 people split $25.48 evenly,
Amount each friend has to pay = Total Cost of pizza/Total number of people
= $25.48/4
= $6.37 per friend
Each friend has to pay $6.37 each if $25.48 is splitted evenly amongst them
Hello, sorry can’t help with that. i guess that’s just the way you are.
Your subtracting 3x from 5x: 5x-3x
This is so you only have a variable on one side
5. To figure this out you must find when y = 0
-16t^2 = -200
t^2 = 12.5
Square root
t = 3.54 C
6.
Axis of symetry = -.5 (always a vertical line down vertex)
Vertex = (-.5, -6.5) (the minimum of the graph)
B
7. To find maximum height you must find the vertex
The maximum height is 549 feet after 5.75 seconds
C
9. Solve for X
x^2 = 1
Square root
X = plus or minus 1
A
