Answer:
18
Step-by-step explanation:
The circumference of the circular table on Beverly’s porch is 72pi inches. The radius of the table is 18 inches.
In order to solve this, we have to use the formula, 72 pi = 2* r * pi.
r = radius
72pi = circumference
Therefore, the radius of the table is 18 inches.
Answer:
First we find the value of x,
x ≥ -4
Step-by-step explanation:
3x+7 ≥ -5
3x ≥ -5 -7
3x ≥ -12
x ≥ -4
Now to graph this inequality, consider number line.
numbers greater than and equal to -4 are -3,-2,-1,0 and so on.
Note that in solution -4 is included so in graphing we use dot (filled circle).
