You and your friend are selling tickets to a charity event. You sell 8 adult tickets and 6 student tickets for $126. Your friend sells 12 adult tickets and 13 student tickets for $209. What is the cost of a student ticket?

Answers

s=cost per student ticket
a=cost per adult ticket

value=(students vlue)+(adults value)
student value=(cost per student) times number of students
adult value=(cost per adult) times number of adults



you sell 8 adult and 6 students and that is a value of 126
8a+6s=126

friend sell12 adult and 13 student and get 209
12a+13s=209

so we have
8a+6s=126 and
12a+13s=209
it might help to simplify  the first equaiton by dividing by 2
4a+3s=63

we have
4a+3s=63
12a+13s=209
multiply first equaton by -3
-12a-9s=-189

add to secont equaiton

12a+13s=209
-12a-9s=-189 +
0a+4s=20

4s=20
divide 4
s=5

each student ticket costs $5.00

there are a total of 120 counters in a box, there are only red counters and blue counters in the box. there are three times as many red as blue counters in the box. carl takes 1/3 of the red counters from the box. kerry takes 80% of the blue counters from the box. work out the ratio of the number of red counters to blue counters now in the box. give your ratio in its simplest form

Answers

Let blue counters = x

Red counters would be 3x ( three times as many)

first find the number of red and the number of blue counters:

3x + x = 120

4x = 120

x = 120/4

x = 30

There are 30 blue counters and 90 red counters.


Carl took 1/3 of the red, 90 / 3 = 30, so there were 60 red counters left

Kerry took 80% of the blue, 30 * 0.80 = 24, so there were 6 blue counters left


The ratio of red to blue would be 60: 6 which can be simplified to 10:1.

The ratio of the number of red counters to blue counters now in the box is 10:1.

What is a ratio?

A ratio is the simplest relation shown between two quantities, in the way x:y, read as "x is to y", and functions as x/y.

How to solve the question?

In the question, we are said that there are a total of 120 counters in a box, there are only red counters and blue counters in the box. there are three times as many red as blue counters in the box. Carl takes 1/3 of the red counters from the box. Kerry takes 80% of the blue counters from the box.

We are asked to work out the ratio of the number of red counters to blue counters now in the box.

We assume the initial number of blue counters in the box to be x.

Then, the initial number of red counters in the box = 3x {three times as many red as blue}.

Therefore, the initial ratio of red to blue = 3x:x = 3:1.

Now, Carl takes 1/3 of the red counters.

The number of red counters left = 3x - (1/3) of 3x = 3x - (1/3)*3x = 3x - x = 2x.

Also, Kerry takes 80% of the blue counters.

The number of blue counters left = x - 80% of x = x - 0.8x = 0.2x

Therefore, the final ratio of red to blue = 2x:0.2x = 10:1 (Simplest form).

When you subtract one negative integer from another, will your answer be greater than or less than the integer you started with??explain you reasoning and give an example. PLEASE HELP ME!!6^_^

Answers

so say for example u have -7 - (-5), think of subtracting integers as adding the opposite, so ur adding the opposite of -5, the opposite of -5 is 5, so ur adding -7 and 5= -2
another one: -15 - (-18)
again, adding the opposite. -15 plus positive 18= 3

What is the quotient of 6 ÷ 1/3 =

Answers

The answer to 6 divided by 1/3 is eighteen
you need to make the 6 into a 6 over 1 than flip the one over three around into 3 over 1 and change the division sign into a multipulcation sign now do 6/1 times 3/1 and get 18/1 now make the 18/1 into just 18. because to do division you don't actually do division you do the inverse operation. hope this helped for this problem and more like this one in the future. also i tried to explain as best as i could sorry if it is confusing.

What is the answer to 3/4 +1/3

Answers

Well, to add fractions, you need to find a common denominator. In this case, the smallest common denominator would be 12. So you must multiply each fraction so that both denominators are 12.
3/4*3/3=9/12
1/3*4/4=4/12
Add those two fractions together, reduce if possible, and you have your answer!
9/12+4/12=13/12
You can't reduce, so 13/12 is your answer.
Hope it helps!

Write 19/25 as a terminating decimal

Answers

Terminating decimals firstly are decimals that finish... 
To transfer 19/25 to a decimal we have to get it out of 100. 
To do this, multiply 19 by 4, and 25 by 4. 
This gives you 76/100.
From here you can easily see the decimal is 0.76. 

= 0.76
