If a=1 and b=-3, what is the value of |a-2| + |2-b|?

|a-2| = 1

|2-b| = 5

Step-by-step explanation:

2 minus negative 3 would equal 5 because positive minus negative equals positive and you are using absolute value. 1 minus 2 would equal -1 but the absolute value is 1 so the answer is 1.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
