City A experienced 18 armed robberies less than twice that of city B. In two cities combined, 138 armed robberies occurred. How many armed robberies occurred in City A?

86 armed robberies

Step-by-step explanation:

Let a represent the number of armed robberies city A experienced and b represent the number of armed robberies city B experienced.

From the first sentence, we know that  a = 2b-18

From the second sentence, we know that a+b=138.

We can solve by substituting the value of a into the second equation to get

(2b-18)+b = 138. Add 18 to both sides and simplify to get 3b = 156. Finally, divide both sides by 3 to get b=52. We can plug this back into the first equation to get a = 2*52 - 18 = 104-18 = 86.

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
