Answer: 33 child tickets that were sold.
Step-by-step explanation:
Let x represent the number of child tickets that were sold.
Let y represent the number of adult tickets that were sold.
At the city museum, child admission is $5.40 and adult admission is $9.10. A total sales of $1079.10 was made on Monday. This means that
5.4x + 9.1y = 1079.1 - - - - - - - - - -1
On Monday, three times as many adult tickets as child tickets were sold. This means that
y = 3x
Substituting y = 3x into equation 1, it becomes
5.4x + 9.1 × 3x = 1079.1
5.4x + 27.3x = 1079.1
32.7x = 1079.1
x = 1079.1/32.7
x = 33
y = 3x = 3 × 33
y = 99
Answer:
<u>-10x (1 - y)</u>
Step-by-step explanation:
<u>Given :-</u>
Side 1 = (2x + 5xy)
Side 2 = (-7x - 10xy)
<u>To Find :-</u>
Perimeter
<u>Formula :-</u>
Perimeter (rectangle) = 2 (Side 1 + Side 2)
<u>Solving :-</u>
Perimeter = 2 (2x + 5xy - 7x - 10xy)
= 2 (-5x - 5xy)
= <u>-10x (1 - y) => [Solution]</u>
Answer:
We have
k^2 - 25f^2 + 5kf - 25f^2 =
k^2 - (5f)^2 + 5f( k - 5f) =
( k - 5f )( k + 5f ) + 5f( k - 5f ) =
( k - 5f )( k + 5f + 5f ) =
( k - 5f )( k + 10f );
