The property shown in #11 is the Associative Property of Addition.
In short, the associative property of addition states that no matter how an additive expression is grouped, the quantity will turn out the same. In this case, the answer is going to be equal whether you decide to add 5 and 8 first or 8 and 11 first.
Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
Answer:
x=8/3
y= -20/9
Step-by-step explanation:
4X + 3Y -4 =0
Linear egquations must in

so 4X + 3Y =4
THEN
3X + 9Y = - 12
next use calculator to solve it or you can use traditional way
They have different masses
The answer is $14 because 65% of $40 is 26 and 40-26=14
