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.

In circle J with mZHLK = 18, find the mZHJK.
zysi [14]

Answer:

The measure of angle HJK is 36°

Step-by-step explanation:

<em><u>In a circle</u></em>, <em>the measure of the inscribed angle equal half the measure of the central angle subtended by the same arc</em>

In circle J

∵ J is the center of the circle

∵ H and K lie on the circle

∴ ∠HJK is a central angle subtended by arc HK

∵ L lies on the circle

∴ ∠HLK is an inscribed angle subtended by arc HK

→ By using the rule above

∵ ∠HJK and ∠HLK are the central angle and inscribed angle

   subtended by the same arc HK

∴ m∠HLK = \frac{1}{2} m∠HJK

∵ m∠HLK = 18°

∴ 18 = \frac{1}{2} m∠HJK

→ Multiply both sides by 2

∴ 36 = m∠HJK

∴ The measure of angle HJK is 36°
