520 x 0.2 = 104
520 + 104 = 625
Curtley's annual heating cost before he got his loft insulated was $624.00
I’m not 100% sure but I think the answer to this would be 21x - 9.
Answer:
the Point is (12,6)
Step-by-step explanation:
We Have Formula ( (b*x1 +a*x2)/a+b , b*y1 +a*y2/a+b)
Where x1 , y1, and x2, y2, are the coordinate points of the line segment that make the line segment. And 'a' and 'b' is the ratio. here the ratio is 3:2 so the a =3 and b=2 . After putting values and of the points and the ratio in the above formula we'll have
(2*0 +3*20)/3+2 , (2*15 + 3*0)/3+2
we'll have 60/5 , 30/5 = (12,6) this will the point that will divides the Libe segment formed from A and B in the Ratio of 3:2.
Answer:
115
Step-by-step explanation:
because all triangles angles equle 180
Answer:
450
Step-by-step explanation:
reduce fraction ; 1200/8 = 150 = x/3
distribute 150 ; 150 x x/3 = 450x
x = 450
