Answer:
2a-6>=15 this is because the key word at least means it can be 15 or higher but it cannot be less than 15.
Step-by-step explanation:
The measure of a straight line is 180
125+30=155
180-155=25
x = 25
9/15 becomes 90/15 but now u have a point on ur answer so it would be .6 as 15 times 6 equals 90
