At the movie theatre, child admission is $5.40 and adult admission is $8.70 . on friday, 159 tickets were sold for a total sales
blondinia [14]
Alright this is gonna be a long one

Lets called child tickets x and adult tickets y 

so x + y should be equal to 159 since they said that the total sum of the tickets is 159 
so thats your first equation : x + y = 159

next form an equation using the prices, 
5.40x + 8.70y = 1079.70

now that you have your two equations, just substitute the first into the second (you could either substitute for x or y by saying x = 159-y or that y=159-x)

Hope this helps.

tatiyna

<em>Missing:</em>

<em>If Hector earned $126 last week, what was the amount of Hector's raise per hour?</em>

Answer:

x = 2.5

Step-by-step explanation:

Given

y=12(8+x)

Required

Solve for x when y = 126

y=12(8+x)

126 = 12(8 + x)

Divide through by 12

\frac{126}{12} = \frac{12(8 + x)}{12}

10.5 = 8 + x

x = 10.5 - 8

x = 2.5

Answer:

Angle 5 = 35 degrees

Step-by-step explanation:

A straight line is equal to 180 degrees, meaning 1 + 2 + 5 = 180 degrees because they make up a straight line.

Angle 2 = 55 degrees

Angle 1 = 90 degrees (because it is a right angle)

Angle 5 = ?

Set up an equation:

90 + 55 + angle 5 = 180

145 + angle 5 = 180

Angle 5 = 35
