Hey there!

Commutative property: 18 + 0 + 34 + 26

Identity property: 34 + 18 + 26

34 + 26 = 60

Associative property: 60 + 18 = 78

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

30 + 0 + 18+26 \\ 34 + 0 = 34 \\  34 + 18 + 26 \\ 34 + 18 = 52\\ 52 + 26  = 78 \\ = 78

Good luck on your assignment and enjoy your [email protected]

The commutative property of addition can be used to rarrange this to

... 0 + 18 + 34 + 26

Then the identity property of addition can be used to remove the 0 term

... 18 + 34 + 26

We can use the associative property of addition to form the sum of 34 and 26, convenient because 4 and 6 "make a 10". That sum is 60, so now the sum is

... 18 + 60

which is easily seen to be

... 78

How is estimation helpful when adding and subtracting decimals
Gnesinka [82]
Its a lot easier to do 1.200 - .200. Than to do 1.248- .239. How I see it, estimating always gives you something to fall back on or to help see if your exact answer is accurate

Slove for x mx+2nx=p
prisoha [69]
Solve for x.

mx+2nx=p

Factor out variable x.

x(m+2n)=p

Divide both sides by m+2n.

x(m+2n) / m+2n = p / m+2n

x=p / m+2n
