<em>Jon is selling tickets for the school talent show. On the 1st day, he sold 3 senior tickets and 12 child tickets for $195. On the 2nd day he sold 13 senior tickets for $299. Find the price of a senior citizen ticket.</em>

<h3>Answer:</h3>

$23

Create a system of equations to help you solve this problem. The system of equations will look like: 3s + 12c = 195 and 13s = 299. The variable s represents the cost of senior tickets and the variable c represents the cost of children tickets.

$\left \{ {{3s~+~12c~=~195} \atop {13s~=~299}} \right.$

Solve the second equation for the variable s as this is the easiest way to solve the problem. Solve the second equation for s by dividing both sides of the equation by 13 to isolate the variable s.

s = 23

Since the question was only asking for the price of a senior citizen ticket, you are technically done. The first equation was only put there to confuse you or allow you to check your work if you needed to. The price of a senior citizen ticket (variable s) is $23.

How do I round 4.75 up to the nearest whole number

Ksenya-84 [330]

4.75.
the whole number is 4
circle 4 and see whether the number beside it
in this case its 7
(Any number that is 5 - 9 causes the number that you are rounding off to to increase)
( any number that is 4-1 causes the number that you are rounding off too to remain)
in this case since its 7 which more that 5 and the whole number increases therefore the final answer is 5.

Hope this helps! xD
would not mind if you put it as the brainliest answer

Q+|6.4|=9.6 with steps?

Bad White [126]

Answer:

Q = 3.2

Step-by-step explanation:

So basically you would first re-order the equation. 6.4 + Q = 9.6

Then after that you will move all the terms containing Q to the left and the rest of them on the right. After that you will -6.4 to both sides of the equation. Which will look like this.

6.4 + (-6.4) + Q = 9.6 + (-6.4)

Then you will combine the like terms.

6.4 + (-6.4) = 0.0

0.0 + Q = 9.6 + (-6.4)
