Answer:
x = 21.3 repeating. so put the - on top of the 3 if you're writing it down
I hope this helps you
2x+7=3x-7
x=14
2x+7+12y+1=180
2.14+8+12y=180
12y=180-36
12y=144
y=12
The question above makes use of the concept of ratio and proportion in a form of scaling. If we let x and y be the true length and width, the equations that best describe them are,
0.5 cm / 1 inch = 2.5 cm / x in ; x = 5 in
0.5 cm / 1 inch = 4.75 cm / y in ; y = 9.5 in
Therefore, the true length and width of Rueben's flag is 5 in and 9.5 in, respectively.

this is because the heart is more muscle than anything! Muscle cells have loads of mitochondria and the mitochondria themselves are even more efficient than your average mitochondria.
