The rule is minus 5.
So 20, 15, 10, 5, 0, -5
X = Lilys weight
x + 34 = Arthurs weight
4x - 180 = combined weight
x + x + 34 = 4x = 180
2x + 34 = 4x - 180
-2x -2x
_________________
34 = 2x -180
+180 + 180
_______________
214 = 2x
107 = x which is Lily's weight
141 = x + 34 which is Arthur's weight
The total weight is 248
which is the answer that you get when you do 4(107) = 180 or
428 -180 = 248
easy
Step-by-step explanation:
if you have for example x^2-4
just graf x^2 and that put down all point for 4
Answer:
Step-by-step explanation:
(1, 5.5) ; (2, 9)
Slope = 

= 7/2
m = 7/2 ; (2 , 9)
y - y1 =m(x -x1)

Multiply the equation by 2

Answer:
-117
Step-by-step explanation:
So, basically all you have to do is use the absolute values in order to use order of operations and simplify it along with the multiplied grouping.
Hope this helps :)
