600 hundred people attended the premiere of a motion picture. Adult tickets cost %5, and children were admitted for $2. If box office receipts totaled $2400, how many children attended the premiere?

Answers

Answer 1
Answer:

Answer:

200

Step-by-step explanation:

Let the number of children be c

and the number of adults be a

Since 600 people in total attended, we can write the 1st equation as:

c + a = 600

Each adult tickets cost $5 and children ticket costs $2 and total sum of tickets is 2400, thus we can write 2nd equation as:

5a + 2c = 2400

Solving the first equation for adults, we have:

c + a = 600

a = 600 - c

We can put this into 2nd equation and solve for children (c). Shown below:

5a + 2c = 2400\n5(600-c) + 2c = 2400\n3000-5c+2c=2400\n-3c=2400-3000\n-3c=-600\nc=(-600)/(-3)\nc=200

Thus, we can say 200 children attended the premiere

How many solutions are there for 10(x + 4) – 3 = 14x + 1

Answers

Answer:

X=9

Step-by-step explanation:

Open the bracket first

10(x+4)-3=14x+1

10x+40-3=14x+1

Let's collect like terms

10x-14x=1-40+3

-4x=-36

Let's make x the subject of formula by dividing both sides by-4

X=9

Therefore the final answer for x is 9
10(x+4)-3=14x+1
10(4x)-3=14x+1
40x-3=14x+1
37x=14x+1
37x=15x
X=2.5
Or your answer will be 37x=15x

ABCD is a square and a semicircle O has a radius of 6. WHAT is the area of this figure?

Answers

I'm assuming the semi circle lies on one of the sides of the square. that means with a radius of 6 the diameter/ side length of the square is 12. the area of a square is length times width so 12×12=144. the area is 144 units^2

Which of the sets of ordered pairs represents a function? A = {(3, −5), (4, 6), (−3, 9), (2, 7)}
B = {(2, 4), (−1, −7), (5, 6), (4, 3)}


Only A

Only B

Both A and B

Neither A nor B

Answers

Answer:

Both A and B

Step-by-step explanation:

A = {(3, −5), (4, 6), (−3, 9), (2, 7)}  

-Each x goes to a different y so this is a function

B = {(2, 4), (−1, −7), (5, 6), (4, 3)}

-Each x goes to a different y so this is a function

Both!!

If you look at it, none of the x values are repeating with a differnt outcome, so you know that they both are correct.
