The equation, a + (b + 7) = (b + 7) + a, is an example of which property?

a. distributive property
b. associative property of addition
c. commutative property of addition
d. associative property of multiplication

B. Commutative Property

Step-by-step explanation:

A. Distributive property :

for example we take 256 × 1008

256 × 1008

256 ×(1000 +8)

(256 × 1000) + (256 × 8)

256000 + 2064

Answer : 258064

Distributive is distributing a number that contains 0's to make it easier for one self

B. Associative Property of Addition :

for example (230 + 125) + (390 + 460)

if we change it like this or in any order than particularly changes the grouping

(230 + 460) + (390 + 125)

D. Associative Property of Multiplication

(230 × 125) × (390 × 460)

it's the same as the previous example just in Multiplication

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
