The expanded form is: 800,000,000+70,000,000+ 6,000,000
36/2=18
18 would be your answer the radius is half of the diameter
It is false. Since you don't know what is the variable equal to. But multiplication can't be in associative property.
We have
3 / (x-5) - x/5
We make the GCF and we have
15/[ 5(x-5) ] - x(x-5)/[ 5(x-5)]
= [ 15 - x(x-5) ] [5(x-5)]
= [ 15 - x^2 + 5x] / [ 5 (x-5) ]
= [15 - x^2 + 5x]/[5x - 25]
An answer to your question is (15-x^2+5x)/(5x-25)
34/100
= 0.34
