At the movie theatre, child admission is $5.30 and adult admission is $8.40. On Wednesday, three times as many adult tickets as
aleksley [76]

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

Which of the following shows an equivalent expression to [(5•3)•12 If only the associative property was used to transform the ex
Strike441 [17]

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

I need the answer to this question? thxs
goblinko [34]

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 = \frac{1}{2} (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
