Answer:
-15
Step-by-step explanation:
x-1/2(x+5)=-10
x-1/2x-5/2=-10
2/2x-1/2x-5/2=-10
1/2x-5/2=-10
1/2x=-10+5/2
1/2x=-20/2+5/2
1/2x=-15/2
x=(-15/2)/(1/2)
x=(-15/2)(2/1)
x=-15/1
x=-15
The difference between the sum of all eight positive integral divisors of 66 and the sum of all eight positive integral divisors of 70 is zero.
<h3>How to find the difference between the integral divisors?</h3>
First let's find the integral divisors. We can write 66 as a product of prime numbers as:
66 = 33*2 = 2*3*11
Then the integral divisors of 66 are:
2
3
11
2*3 = 6
2*11 = 22
3*11 = 33
1 (trivially)
66 (trivially)
The sum gives:
2 + 3 + 11 + 6 + 22 +33 + 1 + 66 = 144
For 70 we have:
70 = 7*10 = 2*5*7
Then the integral divisors are:
1
70
2
5
7
2*5 = 10
2*7 = 14
5*7 = 35
The sum gives:
1 + 70 + 2 +5 + 7 + 10 + 14 + 35 = 144
Then the difference between these two sums is:
144 - 144 = 0
