For a Saturday matinee, adult tickets cost $7.50 and kids under 12 pay

ella [17]

let x = # of adult tickets sold, thus the # of children tickets = 70-x 7.5x + 5(70-x) = 450 ^ 7.5x + 350 -5x = 450 ^ 2.5x = 450-350= 100 x = 40 adults tickets thus 70—40 = 30 children tickets

Maggie bought 3 dozen muffins from a baker for $48. Find the costs of 1 dozen muffins and 9 dozen muffins.

Gennadij [26K]

We will say that d = 1 dozen. and y = cost

we know that 3 dozen is 48. so
3d = 48.

to get the cost of 1d, we have to get the 3 to change into a 1. the only way to do this is to divide 3 by 3. if we divided the left side by 3 we must also do the right so:
3d = 48
1d = 16

so 1 dozen = 16

to change 3d into 9d we have to multiply by 3. we again have to do this to both sides. so:
3d = 48
9d = 144

Please Help!!!

Hoochie [10]

By synthetic division,

-5 | 1 -6 -42 79
. | -5 55 -65
- - - - - - - - - - - - - - - - -
. | 1 -11 13 14

$\implies\dfrac{x^3-6x^2-42x+79}{x+5}=x^2-11x+13+\dfrac{14}{x+5}$
$\implies x^3-6x^2-42x+79=(x^2-11x+13)(x+5)+14$

When $x=-5$ , you're left with a remainder of 14.

Solve for q. √3q + 2 = √5

34kurt

Answer:

$q = 0.0186$

Step-by-step explanation:

To solve for q, we initially place everything with the term q to one side of the equality, and everything without the term q to the other side of the equality.

$\sqrt{3q} + 2 = \sqrt{5}$

$\sqrt{3q} = \sqrt{5} - 2$

We find the square of both sides of the equation. So

$(\sqrt{3q})^{2} = (\sqrt{5} - 2)^{2}$

$3q = 0.0557$

$q = \frac{0.0557}{3}$

$q = 0.0186$
