STEP 1:
determine equations needed

x= # of $10 tickets
y= # of $14 tickets

QUANTITY EQUATION
x + y= 800

COST EQUATION
$10x + $14y= $9,040


STEP 2:
multiply quantity equation by -14

-14(x + y)= -14(800)
-14x - 14y= -11,200


STEP 3:
add new quantity equation in step 2 to cost equation of step 1 to solve for x using elimination

-14x - 14y= -11,200
10x + 14y= 9040
y term cancels out

-4x= -2160
divide both sides by -4

x= 540 ten dollar tickets


STEP 4:
substitute x value in step 3 into either original equation

x + y= 800
540 + y= 800
subtract 540 from both sides

y= 260 fourteen dollar tickets


ANSWER: There were 540 $10 tickets and 260 $14 tickets sold.

Hope this helps! :)

Of the following transformation types, which are examples of isometry?
Brrunno [24]
Isometry means lengths are preserved, and hence shapes must remain congruent.

Any dilation, stretching, etc are therefore excluded.

The transformations on the list that are examples of isometry are therefore:
rotation
translation
reflection

The correct answer is 110 degrees

The value of X is 115
If we substitute X, then the “equation” would be (115)-5=110 degrees :))))
