Answer:
Is That all? i think you missing part of the question XD
how long did the repair take?
Step-by-step explanation:
The first step is correct, because you changed the order of two terms in an addition, and the property is indeed called commutative property of addition.
In the second step, you do the same, but with multiplication: you use . This means that you're using the commutative property again, except for multiplication. So, the answer should be "commutative property of multiplication.
Finally, the third step is correct, because you're distributing the multiplication by 3 to both terms in the parenthesis, and this is called distributive property: it states that
It must be a rhombus, because that's the parallelogram with all sides equal.
It could be a square, but it doesn't have to be. A square is a rhombus
with special angles.
Spain = 140
Italy = 40
France = 60
U.S.A = 120
total = 18,000,000
Spain : 140/360 = 39%.....0.39(18,000,000) = 7,020,000
Italy : 40/360 = 11%....0.11(18,000,000) = 1,980,000
France : 60/360 = 17%....0.17(18,000,000) = 3,060,000
U.S.A : 120/360 = 33%...0.33(18,000,000) = 5,940,000
