Answer:
She went on the slide 8 times and on the roller coaster 4 times
Step-by-step explanation:
We convert each statements to a mathematical equation.
Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.
Mathematically, R + S = 12. ........(i)
Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.
To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.
Mathematically, 25R + 10S = 180 .......(ii)
Here we now have two equations that we can solve simultaneously.
From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:
25(12 - s) + 10s = 180
300 - 25s + 10s = 180
300 - 25s + 10s = 180
300 - 15s = 180
15s = 300 - 180
15s = 120
S = 120/15
S = 8
S = 8 , and R = 12 - S = 12 - 8 = 4
It is 25 percent because 6 goes into 24 4 times
Answer:
4, 7, 10, 13, 16, 19, 22
Step-by-step explanation:
Not sure if there is more to this question but here is what I assume:
We want to find the first 7 terms of this equation given 3n+4
Assuming we are starting at 0 we plug 0 in for n.
3(0) + 4 → 4
So our first answer is 4
We continue by pugging in the next numbers after that to get to the first 7 terms
3(1) + 4 → 7
3(2) + 4 → 10
3(3) + 4 → 13
3(4) + 4 → 16
3(5) + 4 → 19
3(6) + 4 → 22
Eleven minus four equal seven
11-4=7
