The answer is 2.84 so the best estimate is 3.00<span />
Let
x---------> the number
we know that
[9+2x]*4=4x+12
36+8x=4x+12
8x-4x=12-36
4x=-24
x=-24/4
x=-6
the answer is
-6
To find the diameter of a circle, using only the circumference, you need to divide the circumference by π, or 3.14.
So in this case, you must divide 12 by 3.14, which gives you 3.82.
I even double checked this, and should be correct then.
Answer:
The answer is c
Step-by-step explanation:
5x+17+15=45
5x=45-17-15
5x=13
x=13/5
