in local theaters showing an animated movie they charge $5 per ticket for a child and $12 per ticket for an adult they sell a total of 342 tickets and make a total of $2,550 we want to try to find out how many of each type of ticket they so let C represent the number of children tickets sold and A represent the number of adult tickets to write an equation that represents the fact that 342 tickets were sold also write an equation representing the fact that they made it to a total of 2550 also solve the system you created in A & B by the method of elimination

Answers

Answer 1
Answer:

Answer: C=222 and A =120

Step-by-step explanation:

Let C be the number of children tickets and A be the number of adult tickets.

Then, According to the question, we have the following system:-

C+A=342........................(1)\n5C+12A=2550........................(2)

Multiply equation (1) by 5 on both sides ,we get

5C+5A=1710..........(3)

Eliminate equation (3) from equation (2), we get

7A=840\n\Rightarrow\ A=120

Substitute the value of A in (1), we get

C+120=342\n\Rightarrow\ C=222

Hence, the number of children tickets sold = 222 and the number of adult tickets sold =120
Answer 2
Answer: C+A=342
$5C+$12A=$2,550

5C+5A=1710
5C+12A=2550
-7C=-840
C=120

5(120)+12A=2550
600+12A=2550
12A=1950
A=163

Simplify radical. Intermediate Algebra

Answers

180 ÷ 2 = 90; 90 ÷ 2 = 45 ; 45 ÷ 3 = 15 ; 15 ÷ 3 = 5 ; 5 ÷ 5 = 1 => 180 = (2^2) * (3^2) * 5 => √(180) = 2*3 * √(5 )=6 √(5) ;

In the same way we have √(245)=7 √(5) ; and √(320 )=8 √(5) ;

Finally, 6 √(5)+7 √(5) - 8 √(5) = 13 √(5) - 8 √(5) =7 √(5).

six girls and four boys have entered the science fair. first, second, and third place awards are to be given out. what is the probability that exactly one girl and two boys will recite awards? express your answer as a percent

Answers

The probability  that exactly one girl and two boys will recite awards is 10%.

Probability

Given:

6 girls +4 boys

Hence:

Probability of a girl  getting the first place =6/10

Probability of a boy  getting the second place=4/9

Probability of a boy  getting the third place=3/8

Total probability:

Total probability=6/10×4/9×3/8

Total probability=0.1×100

Total probability=10%

Therefore the probability  that exactly one girl and two boys will recite awards is 10%.
