Total: 318
Student tickets: x
Adult tickets: 3x+6

x+(3x+6)=318 -> 4x+6=318 -> 4x=312 -> x=78

3(78)+6 = 234+6 = 240

240 adult tickets were sold

Let x= the part of the problem you don't have any information in his case it's the students let x= students 3x+6= adults x+3x+6=318 4X=312 X=78 students 3x78+6= 240 adults

Let's simplify everything.
-5n-8-56n=8
Put the variables on one side and the numbers on the other.
-5n-56n=8+8
Combine like terms.
-61n=16
n=-16/61

Question 5 (12 points)

Dima020 [189]

Answer:

see attached for diagram

a) √13

b) √29

c) 4

Step-by-step explanation:

Equation of the circle: $(x + 1)^2 + (y - 3)^2 = 16$

⇒ center = (-1, 3)

⇒ radius = √16 = 4

Distance between 2 points formula:

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

a) let (-1, 3) = $(x_1,y_1)$

let (2, 1) = $(x_2, y_2)$

$\implies \sqrt{(2+1)^2+(1-3)^2} =\sqrt{13}$

b) let (-1, 3) = $(x_1,y_1)$

let (4, 1) = $(x_2, y_2)$

$\implies \sqrt{(4+1)^2+(1-3)^2} =\sqrt{29}$

c) let (-1, 3) = $(x_1,y_1)$

let (3, 3) = $(x_2, y_2)$

$\implies \sqrt{(3+1)^2+(3-3)^2} =4$

1 cup of chocolate chips for every 1and 3/4 cup of flour

so divide 4 and 2/3 x 1 and 3/4

turn them both into fractions

4 2/3 = 14/3

1 3/4 = 7/4

14/3 / 7/4 = 14/3 x 4/7 = 56/21 = 2 and 2/3 cups of chocolate chips are needed
