the answer will always be the same.5 + (2+3) = (5+2) +3ANSWER = associative.3) 5p -1 = 2p +203p = 21p = 7 ANSWER4) 5-4 = 1 ANSWER-1) x=2, 5 by 2 -7= 28Correct! (7,28)2) (2) Commutative Law.......
= + 2 su root 5 - 2 sq root 5 - 4
= - 4
= 1
Answer (1) is the solution!
Cheers!!!
-
1) 5x - 7 = 28
5x = 35
x = 7 ANSWER
2) An operation is associative if you can group numbers in any way without changing the answer. It doesn't matter how you combine them, the answer will always be the same.
5 + (2+3) = (5+2) +3
ANSWER = associative.
3) 5p -1 = 2p +20
3p = 21
p = 7 ANSWER
4) 5-4 = 1 ANSWER
-
1) x=2, 5 by 2 -7= 28
Correct! (7,28)
2) (2) Commutative Law.
3) Grouping like terms, 5p - 2p= 20 + 1
3p= 21
p=7
4) Difference of 2 squares rules: (1), ie 1.
Using Ddistributive law, you exapnd to get 5+2sqrt(5) - 2sqrt(5) -4
-
1. 5x - 7 = 28
5x = 35
x = 7 <- 1
2. b. Commutative. You should add the numbers inside the parenthesis first.
3. 5p - 1 = 2p + 20
3p = 21
p = 7 <- 4
4. (√5-2) (√5+2)
5 - 4 = 1 <- 1
-
1. 5x-7=28
5x=28+7
5x=35
5x/5=35/5
x=7
i dont remeber how to do the rest of your question
-
1.) 5x - 7 = 28
5x = 35
x=7 (1)
2.) associative (3) : you are changing the grouping
3.) 5p -1 = 2p + 20
3p -1 = 20
3p = 21
p = 7 (4)
-
1) 7
2.) associative
3) 7
4) 1
I hope I helped..//
