The rotational symmetry has more than one order of rotational symmetry the objects can fit itself within 360 degrees.
Answer:
C
Step-by-step explanation:
Work backwards. You are given -3 , -30 for C. If you add -3 + 3 and the divide it by 2 , you get 0. If you add 8 + -20 and divide by 2 you get -6 , so the answer is C.
Or, is it asking you to subtract the? In that case
5/4 - 3/8 = 7/8
To find this, just plug the numbers into the expressions.
5x = y
5(2) = 7
10 = 7
So it can't be A.
x + 2 = y
2 + 2 = 7
4 = 7
x + 4 = y
2 + 4 = 7
6 = 7
2x + 3 = y
2(2) + 3 = 7
7 = 7
The correct answer is
D. 2x + 3
