The local theater is showing a matinee and offering a special deal for the community. A ticket for an adult costs $11 and a tick

Irina-Kira [14]

First, x+y=60 and solve for x

x= 60-y

Then set up the equation 11x+6y=460

Since, x=60-y, you plug in for y

11(60-y)+6y=460

660-11y+6y=460

660-5y=460

660-660-5y=460-660

-5y=-200

Divide both sides by 5 (you can drop the negative because they are both negative)

5y/5 = 200/5

y=40

Then take y & plug it back into the original equation of:

x+y = 60 (solve for x)

x+40=60

x+40-40=60-40

x=20

The answer is 20 adult tickets (x) and 40 child tickets (y) were sold.

Answer:

a = ±10/9

Step-by-step explanation:

$-100+81a^2=0\\81a^2=100\\a^2=\frac{100}{81}\\\sqrt{a^2}=\sqrt{\frac{100}{81} }\\a=10/9\\a=-10/9$

Answer:

23 degrees

Step-by-step explanation:

Find the diagram attached

The sum of angle on the straight line is 180°

103+3x+15+x+10 = 180

128+4x =180

4x = 180-128

4x = 52

x = 52/4

x = 13

The measure of the angle of the intersection between Derby Drive and Rosemont is x+10

= 13+10

= 23 degrees

Hence the measure of the angle is 23 degrees
