9 and 7 are the numerators. The greatest common factor between 3 and 7 is 21. Whatever u multiply the bottom by u have to multiply the top by as well
3x + 2y = $134
2x + 3y = $146
Using elimination to solve for x
9x +6y = 3*134 Multiplying 1st equation by 3
-4x -6y = -2*146 | Multiplying 2nd equation by -2
5x = 3*134 - 2*146
5x = $110
x = $22, the cost of the youth ticket
Put x= 22 Into An Equation Then Solve For y
3(22)+2y= 134
66+ 2y=134
Subtract 66
2y=68
Y= 34
CHECKING Answer ($34 being the cost of the adult ticket) y = (134-3*22)/2
3*$22 + 2*$34 = $66 + $68 = $134
C. the values can be added after making a conversion of units because they both measure length.
I think the answer is D. hours because its variation does not depend on another variable
