X=number of adults, y= number of students
x+y=12
18x+12y=162
You can simplify the second equation by dividing by six: 3x+2y=27
Rearrange the first equation: y= 12-x. Plug y into the simplified second equation:
3x+2(12-x)=27
3x-2x+24=27
x=3.
Plug the now known x value into y=12-x. So y= 9.
Therefore, there are 3 adults and 9 students.
Answer:
$68.54
Step-by-step explanation:
If you want some help here, I can tell you!
60% is 60%, since the best way to find out is by converting the two numbers into percents.
You need to find out a decimal first for the second number in order to convert it to a percent. To find a decimal out of a fraction, you put the numerator in the house (I forgot what it was called) and then you put the denominator out. You divide, and you find that 1/3 is actually a repeating decimal, 0.33333333 and so on. You round to 0.34, and that's 34% since 0.34 is 34 out of 100, basically. 34% plus 60% is NOT 100%, and 100% is a whole, so that's why it isn't accurate.
I = Prt
I = ($19,200)(12%)(5)
I = $11,520
The boat would cost $11,520 in 5 years.
Answer:
C) 2(20)
Step-by-step explanation:
In a football game there are 2 teams playing against each other so there are 2 possible winners in a game as either of the 2 teams can win the game. So there are 2 ways to make prediction of winner for a game.
Since, there are 20 football games in total, and predictions of winner per each game are 2, so the possible predictions for 20 games would be 2 x 20
Hence, 2(20)=40 different predictions would be possible for 20 football games.
