It's "commutative property," which says that (for addition/multiplication) order of the operator doesn't matter. For eg, 3 * 5 = 5 * 3.
Associative property (again, of multiplication and addition) means that it doesn't matter how you solve an expression if the same operand is used and some numbers are grouped. For eg. 3 * (5 * 4) = (3 * 5) * 4.
2x+4y=8
-2x -2x
4y=-2x+8
/4 /4 /4
y=-1/2x+2
To solve for x you do these steps
x=number
1. do this following multiplication problem to get 0.9%
36/x*100%= 0.9%
2. now do the opposite of what you did before to get x
36 divided by 0.9%= x
36 divided by 0.9%= 40
x = 40
Answer:
simple even tho im in 6th grade it would be over $100
The answer is 3√5. You use the distance formula: √((x2-x1)^2+(y2-y1)^2)
