Answer:
63%
Step-by-step explanation:
12/19=0.63157895
0.63157895*100=63.1578947
I think it’s 82 because 78+4=82
8x -5+2 x
8x+2x-5 ( combine like terms)
answer:
10x-5 or -5+10x
Because of rules of geometry we know that a+b=180 degrees so we can add the equations together and set that equal to 180 and solve
6x-48+4x+38=180
subtract 38 from both sides and add 48 to both sides
then add like terms
10x=170
and divide by 10 to get
x=17
The diameter is the cross section of the widest part of a sphere.
