Answer:
4,800
Step-by-step explanation:
Sorry I don't know how to explain it scientifically but I know how to do the calculations
1) Theres 60 minutes in an hour
2) 80x60= 4,800 beats
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.
Solution:
we have been asked to find the product of (x+y+3)(x+y-4).
we will multiply term by term as below
Hence the the product of (x+y+3)(x+y-4) is
