19 more than 9 times a number is less than or equal to 163. Which of the following represents the solution set of this problem?

x ≤ 6

Step-by-step explanation:

Let the unknown number be x;

9 times the number is expressed as 9x

9 more than 9 times a number is expressed as 9x + 9

9 more than 9 times a number is less than or equal to 163 is then expressed as;

9x + 9≤ 63

≤ is the less than or equal to sign

Find the solution;

9x ≤ 63 - 9

9x≤54

x ≤ 54/9

x≤ 6

Hence the required solution is x ≤ 6

step-by-step explanation:

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
