Answer:
1,-1,3,-3
Step-by-step explanation:
your P is the first number or the number with the highest exponent, your Q is the last number or the number with no variables. So you make a list of what multiplies to your P's and what multiplies to your Q's and you divide your P list by Q. So 3 is made by -1,1,-3,3 and -1 is made by -1,1. So dividing that you get your list of -3,-1,1,3
2/3y- 2/5 =5
add 2/5 on both sides:
2/3y = 5 + 2/5
Combine the fraction:
2/3y = 5 2/5
Write in improper Fraction:
2/3y = 27/5
Divide both sides by 2/3:
y = 27/5 ÷ 2/3
Change divide fraction to multiplication fraction:
y = 27/5 x 3/2
y = 81/10
Write in mixed number:
y = 8 1/10
Answer: y = 8 1/10
Answer:
ab=ba, 5(3x-2)=5.(3x)-5.(2)=15x-10, , 32y+12y=44y, 12+3x-x-12 = 2x
Step-by-step explanation:
In the given questions
3) ab is given it is which is written as
By Commutative property , ab=ba
4) 5(3x-2)
By distributive property,
5(3x-2)=5.(3x)-5.(2)=15x-10 (∵a(b+c)=a.b+a.c)
5)
By distributive property, (a(b+c)=a.b+a.c)
which is not equivalent to 2-2x
6)
By distributive property, (a(b+c)=a.b+a.c)
which is not equivalent to 3-x
7) 32y+12y
32y+12y=(32+12)y (∵ distributive property)
= 44y
8) 12+3x-x-12
12+3x-x-12=12+(3-1)x-12 (∵ distributive property)
= 12+(2x-12)
= 12+(-12+2x) (∵ commutative property)
= (12-12)+2x (∵ associative property)
= 2x
