Answer:
47
Step-by-step explanation:
Let a, b, and c be those three numbers.
When two of the three numbers are added at a time, the possible sums are 32, 39, 23. Let
Add these three equations:
Divide this equation by 2:
The sum of all three numbers is 47.
#7 is C-180°
it’s a fact all angles of a triangle add up to 180°
<h3>Answer: A) 2</h3>
=====================================================
Work Shown:
u(50654) = 5+0+6+5+4 = 20
u(20) = 2+0 = 2
u(50654) = 2
We want to find all possible values of m such that u(m) = 2 and also m is some two-digit integer.
-----
Possible values of m are: m = 11, m = 20
u(m) = u(11) = 1+1 = 2
u(m) = u(20) = 2+0 = 2
and that's it. There are no other ways to have two positive integers add up to 2.
I hope this helps you
