Eight people go to a movie. Adult tickets cost $15 and children's tickets cost $8

Mathematics
1 answer:
Reptile [31]2 years ago
5 0

Answer: number of adults = 3, number of children = 5

Step-by-step explanation:

let the number of adults be x, and the number of children be y.

x + y = 8 , 15x + 8y = 85

1st equation x 8 = 8x + 8y = 64

8x+8y-15x-8y = 64 - 85\\-7x = -21\\x=3

substitute x=3

3+y=8\\y=5

<em>Step-by-step explanation:</em>

<em>Part A:</em>

<em>So we know that the bacteria doubles every (30) minutes.</em>

<em>2000 times 2 equals 4000 (30 minutes)</em>

<em>4000 times 2 equals 8000 (1 hour)</em>

<em>Answer for Part A:</em>

<em>8000 bacteria</em>

<em>Part B:</em>

<em>Now we do this function 2000(2)^14 (30 minutes long)</em>

<em>Answer to Part B: </em>

<em>I believe the answer is 32,768,000 (Please correct me if I'm wrong) </em>

If i kick a soccer ball 10 feet and i comes back, how did this happen
Harman [31]
It likely hit a barrier like a wall for example and the force of the ball hitting the wall caused it to be pushed away. Another possibility is that the ball was kicked up some sort of slop and when it was at the ten feet it slowed down and then rolled back down. I hope this helps.

F is between E and G. EF=3X, EG= 11x-2, FG= 5x+16. Find the value of the variable
Salsk061 [2.6K]

9514 1404 393

Answer:

  x = 6

Step-by-step explanation:

The sum of segments is used:

  EF +FG = EG

  3x +(5x +16) = 11x -2 . . . . substitute given expressions

  8x +18 = 11x . . . . . . . . add 2

  18 = 3x . . . . . . . . subtract 8x

  6 = x . . . . . . divide by 3

The value of the variable is 6.

__

<em>Check</em>

The segment lengths are ...

  EF = 3x = 3·6 = 18

  FG = 5x+16 = 5·6 +16 = 46

  EG = 11x -2 = 11·6 -2 = 64 = 18+46 . . . answer is correct

What is the value of p?<br><br> A. 125°<br> B. 45°<br> C. 35°<br> D. 550
Vikki [24]

Answer:

C- 35 °

Step-by-step explanation:

Interior angle adjacent to 90° angle = 90° (supplementary angles of a line segment).

Interior angle adjacent to 125° angle = 55° (supplementary angles of a line segment).

Sum of two interior angles of the triangle = 55+90 = 145°

∠p = 180° - 145° = 35°
