Communitive property is the property that allows you to move the numbers around in addition and multiplication.
For example:
(addition) 1 + 2 = 2 + 1
(multiplication) 3 x 4 = 4 x 3
This property cannot be used in division or subtraction
Answer:Perimeter of a rectangle is 2*the length plus 2*the width
P = 2L + 2W and P = 130, so
L + W = 65
Three times the length is equal to 10 times the width, giving
3L = 10W
Substituting into the above for L = 65 – W,
3(65 – W) = 10W
195 – 3W = 10W
195 = 13W
W = 195/13 = 15
W = 15 yards,
And L = (10/3)W = (10/3)*15 = 50
L = 50 yards

Step-by-step explanation:
Because both equations are equal to y, you can set the equations equal to each other.
2x+5= x+3
-x -x
x+5=3
-5 -5
x= -2
Then, you can substitute -2 to any equation to find x.
y= (-2)+3 y= 2(-2)+5
y= 1 y= -4+5
y=1
:
x=-2
y=1
answer
13x 60 (hours change to minutes )
11 (hours changes to minutes)
(11x60)
=660
so the answer
