Answer:
<3 and <6 is Alternate interior angles.
<4 and <5 is Alternate interior angles.
<2 and <7 is Alternate exterior angles.
<3 and <7 is Corresponding angles.
Hope this helps. :)
Consider expression First, you can factor it:
Since x is integer number, then you can see that x-1 is previous integer number (x-1 is 1 unit smaller than x).
Therefore, x-1 and x are two consecutive integers. When you have two consecutive integers, one of them is always even and one is always odd. Multiplying even integer number by odd integer number you always get even integer number.
Thus, is always even.
Let's say the number is x
75%of x is 15
75%x=15
0.75x=15
x=15/0.75
x=20
or you can say 3/4x=15
x=15*4/3
x=20
I'm pretty sure the answer to your question would be A
