Use properties of operations to determine whether 4r + 4t and 4(r+t) are equivalent. Explain your answer.
Vikki [24]

There is only one property used to determine whether

4r+4t=4(r+t).

The property is called the distributive property and in a nutshell it states, a(b+c)=ab+ac, which means a is distributed through b+c using multiplication. So 4(r+t) says, distribute 4 to r and t which then translates into 4r+4t.

there are 3 slices of pie left, and the angle measurement is 72 degrees, how many slices was the pie cut in to
Daniel [21]
15; this is because 3 pies make up 72
with this you can make it so that 3x=72 
After this you need to find x which is a single pie
so; (3x/3)=(72/3)
      x= 24
Since you know a circle is 360 degrees all around the center
You can do 360/24 making it 15 pies.
