Answer:
39
Step-by-step explanation:
Let x = number of child tickets sold.
Cost of x child tickets is x * 5.30 = 5.3x.
"three times as many adult tickets as child tickets were sold"
Number of adult tickets sold: 3x
Cost of 3x adult tickets is 3x * 8.40 = 25.2x
Cost of all tickets is 5.3x + 25.2x = 30.5x
Cost of all tickets is $1189.50
30.5x = 1189.5
x = 1189.5/30.5
x = 39
Answer: 39
Answer:
[5 . (3 . 12)] shows an equivalent expression to [(5 . 3) . 12] if only the associative property was used to transform the expression ⇒ 1st answer
Step-by-step explanation:
The associative property means you can add or multiply some numbers without matter where you put the parenthesis
Ex: (a + b) + c = a + (b + c) <em>OR</em> (a . b) . c = a . (b . c)
<em>In associative property we move the parenthesis only (we do not move the numbers)</em>
Subtraction or division are not associative
∵ The expression is [(5 . 3) . 12]
- The parenthesis are around the first two numbers, then the
equivalent expression is the one whose parenthesis are
around the last two numbers
∴ The equivalent expression is [5 . (3 . 12)]
∴ [(5 . 3) . 12] ≡ [5 . (3 . 12)]
[5 . (3 . 12)] shows an equivalent expression to [(5 . 3) . 12] if only the associative property was used to transform the expression

Answer:
RS = 19
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle then it is half the length of the third side, that is
- 5x + 44 = 
(18 + 4x) ( multiply both sides by 2 to clear the fraction )
- 10x + 88 = 18 + 4x ( add 10x to both sides )
88 = 18 + 14x ( subtract 18 from both sides )
70 = 14x ( divide both sides by 14 )
5 = x
Then
RS = - 5x + 44 = - 5(5) + 44 = - 25 + 44 = 19
