Answer:
x = 8, y = 3
Step-by-step explanation:
3x - 12y = 60
x + 2y = 14
3x - 12y = 60
3x + 6y = 42 (multiply by 3 so the x is the same as the top equation)
6y = 18 (subtract the equations)
y = 18 / 6
= 3
To find x, substitute y into the 2nd equation since it is the simplest so:
x + 2(3) = 14
x + 6 = 14
x = 14 - 6
= 8
<span>A bilaterally symmetrical animal, like a lobster, fish, or human, can only be cut in one way to get equal halves. Bilateral symmetry leads to cephalization; that is, sensory organs and the brain get moved to the head end of the animal. This is good for predators, for chasing their prey, etc. But it may make it harder for them to detect animals going after them.

Answer:
70.6 cm
Step-by-step explanation:
The length is 30 cm so you multiply by 2 which is 60 and the height is 53 mm so you multiply that by 2 and get 106 mm
to convert millimeters to centimeters you just divide the length value by 10 :)
so 10.6+60=70.6 cm
