Step-by-step explanation:
1/a + 1/b + 1/c = 1/(a+b+c)
=> 1/a + 1/b = 1/(a+b+c) -1/c
=> (b+a)/ab = {c - (a+b+c)/c(a+b+c)
=> (a+b)/ab = -(a+b)/(ac+bc+c^2)
=> 1/ab = -1/(ac+bc+c^2)
=> -ab = ac+bc+c^2
=-c^2 = ab+bc+ca
Similarly we can show that
-b^2 =ab+bc+ca and -c^2 = ab+bc+ca
So a=b=c. since -a^2 = -b^2 = - c^2
Then 1/a + 1/b + 1/c = 1/(a+b+c) => 3/a= 1/3a
=> 1/a^5 + 1/b^5 + 1/c^5 =3/a^5=(( 3/a )(1/a^4)
= 1/3a × 1/a^4 = 1/3a^5 = 1/(a^5 +b^5+c^^5)
Hope it help
Answer:
43 and 41
Step-by-step explanation:
2n-1+2n-3=84
4n-4=84
4n=88
n=22
2(22)-1 and 2(22)-3
44-1 and 44-3
43 and 41
write these numbers according to the directions (in least to greatest form) and you get the numbers 41 and 43.
.
Odd integers can be written in as 2n-1, 2n+1, 2n+3 and so on. Basically, by writing 2n, you guarantee an even integer and when you add an odd integer to an even integer, you get an odd integer. Try using 2n-1 and 2n+1 as your consecutive odd integers and you will get the same solution.
Answer:
Veronica ran 3.075 miles.
Step-by-step explanation:
In order to find how far Veronica ran, we'll have to multiply the amount of times she ran around the track by the length of the track.
1.5 * 2.05 = 3.075
You can leave the answer as is or round it to 3.1
188=28 v-8
28 v=188+8
28 v += 196
v=7
there u go !!!!
The answer is 65.9 because the place right after the decimal is the tenths place
