7/8 yard of fabric because if you turn them into mixed numbers you can subtract them and get 7/8
y = 10 and x = 12
Because we know that 6y and the blank angle next to 13y - 10 are alternate interior angles, and these angles are equal, then the blank angle next to 13y - 10 must equal 6y.
Since 6y and 13y - 10 are next to each other on a 180 degree line, then added together those angles must equal 180 degrees. We can set up an equation to solve:
6y + (13y - 10) = 180
19y - 10 = 180
19y = 190
y = 10
The same applies for the top, 6y and 9x +12 are on a 180 degree line. We can make another equation
6y + (9x + 12) = 180
We know the value of y so we can plug it in and solve for x now
6(10) + 9x + 12 = 180
60 + 12 + 9x = 180
72 + 9x = 180
9x = 108
x = 12

Step-by-step explanation:
perimeter is to add all sides
73m= 16+B+C
{ use algebra}
C is a, B is twice C, hence 2a
a+2a(+16)=73
3a=73-16= 57
3a=57, divide
a= 19
B=19×2= 38m
C=19m
C is 19m
Well, first of all, since both terms have
in them, u can simplify like a regular equation
2-1=1
so the answer is just
