The equations below represent the numbers y of tickets sold after x weeks for two different local music festivals.
kiruha [24]

Answer:

Part a) 3.5 weeks

Part b) 185 tickets

Step-by-step explanation:

Part a) After how much time have the same number of tickets been sold for both festivals?

Let

x -----> the number of weeks

y ----> the number of tickets sold

we have

<em>Country Music Festival</em>

y=10x+150 ----> equation A

<em>Pop Music Festival</em>

y=20x+115 ----> equation B

Equate equation A and equation B

20x+115=10x+150

solve for x

20x-10x=150-115

10x=35

x=3.5\ weeks

Part b) What is the number of tickets sold at that time?

substitute the value of x=3.5 weeks  in the linear equation A or linear equation B

y=10(3.5)+150

y=35+150

y=185\ tickets

FIRST TO ANSWER, would be marked as brainliest:)
boyakko [2]

Answer:

100 Cos 40° + 100 Sin 40° ≈ 141 yards

Step-by-step explanation:

From the diagram, side x is adjacent to the angle 40° while side y is the opposite to that same angle

This means that;

Cos 40° = x/100

x = 100 Cos 40°

Sin 40° = y/100

y = 100 Sin 40°

Therefore, total distance walked = x + y

                         "                             = 100 Cos 40° + 100 Sin 40° ≈ 141 yards

Answer:

54 9/10

Step-by-step explanation:

The perimeter is the sum of all the sides

13 1/4 + 12 1/5 + 18 1/4 + 11 1/5

Add up the whole numbers

13+12+18+11 = 54

1/4+1/5+1/4+1/5

2/4+2/5

1/2+2/5

Get a common denominator

1/2*5/5 + 2/5*2/2

5/10 +  4/10

9/10

Add them back together

54 9/10
