Translate in numerical form. "three times a number is greater than or equal to 12 and less than 21"

21 > 3x ≥ 12

Step-by-step explanation:

Let's represent "a number" with the variable x.

Keep in mind: times means multiplication. *

21 > 3x ≥ 12

The part on the left shows us that the 3x is less than 21. The part on the right shows that it's greater than or equal to 12.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

unless if u could do my questions, if not i wouldn't want to
