Answer:
adults ticket sold= 60
student tickets =125
Step-by-step explanation:
So we need to make a system of equations. Lets say the variable a stands for adults tickets and the variable s stands for student tickets. Our first equation is going to be
s-a=65
that is because there are 65 more student tickets than adults.
the second equation is going to be
3s+5a=675
that is because the tickets will add up 675.
Now we have to make sure one of the variable cancels out when we add them together. So we have to multiply the first equation by 5.
5[s-a=65]
3s+5a=675
So then we end up with
5s-5a=325
3s-5a=675
We need to add them together and we end up with.
8s=1000
We need to divide by 8
s then equals 125.
So there are 125 students tickets.
We now plug 125 back into one of the equations. To make things easy lets to the first equation.
s-a=65
125-a=65
move the 125 over
-a=-60
multiply by a negative
a=60
So you have 60 adults tickets
<span>The correct
answer is 3.24 grams per cubic centimetre. As a matter of fact, the
lunar soil’s mean density may range from 2.90 to 3.24 g cm-3 which highly
depends on the type of ingredients present in its resource materials.</span>
Answer:
In this data set, the <u>number 8 is an outlier. </u>
<u> An outlier is a value that is far away from the rest of the numbers </u>(either a lot smaller or a lot greater).
Because there is an outlier, the measure of center that best represents the data would be the <u>median (the middle value)</u>.
<u> The mean will not be accurate because the outlier will make it smaller than what is actually being represented in all of the numbers but one.</u>
Hope this helps!!!!
Answer:
To find the number of cards, you must use the equation c = 300 + 17d. Collecting your known information in an organized form will be realllly helpful now and in the future. C represents the number of cards, while D represents the number of days!
Step-by-step explanation:
Starting with the original amount, which is 300---->
Here is the answer:
15 - 1 + 3 = 17 extra cards per day
Answer:
16 cm squared
Step-by-step explanation:
Assuming the length of the square is x
We get that the length of rectangle is 2x and width is x.
Using formula of area:
32.= 2x * x
32/2 = x * x
16 = x * x
X = 4cm.
So area of squarr is
X * x= 16 cm ^2
