Answer:
a) Let Kim's age be k, then Kim's sister's age is k/2
k+=24
b) k+=24
1k=24
k=16
=8
Kim's age is 16 while her sister's age is 8.
You start with: (assuming x equals the cost to enter and y the cost of going on the rollercoasters.)
x+5y=35
x+11y=59. Multiply the top equation by -1, and subtract the equations, giving you -6y=-24, divide by -6 into both sides of the equation, to get y=4. Now replace y in one of the original equations (I recommend x+5y=35) and solve for x, giving you x=15
The cost for entering is 15 dollars, while each coaster is 4 dollars more. You could simplify this by changing y into x and making it slope-intercept form, to track your cost. y=4x+15, so it has a slope of 4, and a y-intercept of 15. This answer should give you a good grade on a test.

Step-by-step explanation:
=)
The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:
When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes
Rewrite as:
Divide both sides by 16t
Hence, it takes the rocket 25 seconds to hit the ground
