n, n + 2, n + 4 - three consecutive even integers
3n = 2(n + 4) + 4 |use distributive property
3n = (2)(n) + (2)(4) + 4
3n = 2n + 8 + 4
3n = 2n + 12 |subtract 2n from both sides
n = 12
n + 2 = 12 + 2 = 14
n + 4 = 12 + 4 = 16
Answer: 12, 14, 16.
Answer:
n = 10
Step-by-step explanation:
move all terms to the left:
-2-(-(n-8))=0
calculate terms in parentheses: -(-(n-8)), so:
-(n-8)
get rid of parentheses
-n+8
add all the numbers together, and all the variables
-1n+8
go back to the equation:
-(-1n+8)
get rid of parentheses
1n-8-2=0
add all the numbers together, and all the variables
n-10=0
move all terms containing n to the left, all other terms to the right
n=10
Mass divided by volume = density... I dont know the exact answer but i hope this helps
