The graph shows a proportional relationship between the number of books sold at a yard sale and the amount of money collected from book sales. What is the constant of proportionality? 0.67 1 1.5 2

c  1.5

Step-by-step explanation:

You take the y 6 then divide by the x 4 which equals 1.5 which is the constant of proportionality!!

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

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
