Does it matter what order you add the numbers in a problem? explain how chips and numbers lines support your answer.
Mrac [35]

Answer: No, it does not matter.

Step-by-step explanation:

In addition the order does not matter, this is because of the commutative property of the addition, that says that: A + B = B + A

and the associative property, that says that:

A + (B + C) = (A + B) + C

for example, if you have 4 chips and your friend gives you her 5 chips, now you have a total of 4 + 5 =  9 chips.

The case is the same if you have 5 chips and your friend gives you 4 chips, now you have 5 + 4 = 9 chips.

Other example is that:

5 chips + ( 2chips + 1 chip) = 5 chips + 3 chips = 8 chips

(5 chips + 2 chips) + 1 chip = 7 chips + 1 chip = 8 chips

You can see that the order does not matter.

Please help!!!!!!!!!!!!
Nadusha1986 [10]

Answer:

122.24 is the approximate answer

Step-by-step explanation:

The Logo is made up of 2 semicircles and 1 rectangle

Two semicircles make one circle

The formula for a circle is πr^{2}

The radius (r) is 4 because the diameter is 8

so you plug it in and get 16π

The approximate value of π is 3.14

16 times 3.14 is 50.24cm^{2}

so to calculate the area of the whole logo just add72cm^{2} +50.24cm^{2} =122.24

Question
MariettaO [177]

Answer:

Your friend sold (5w + 1) subscriptions.

You sold (3w + 4) subscriptions.

The difference between what your friend sold and what you sold is

(5w + 1 ) - (3w + 4)

= 5w + 1 - 3w - 4

= 5w - 3w + 1 - 4

= 2w - 3

Answer: 2w - 3

If it is negative then it means the subscription sold by friend is less than the subscription sold by me and if it is positive then it means the subscription sold by friend is more than the subscription sold by me.
