Hello!
A negative number divided by a negative number is a positive number. If our problem contains an odd number of negatives, it is negative.
Therefore, our correct answer is D. -3/-2 (which is 6).
I hope this helps!
First, let's get rid of the unneeded info.
Oldest brother has $108 (3/5 the total)
Youngest brother has $x (1/10 the total)
Next let's find out the total. We do this by multiplying the oldest brothers money by 5/3 (the reciprocal).
108 × (5/3) = 180.
So the total amount of money is $180.
Finally, do 180 × (1/10) to find the youngest brother's amount.
180 × (1/10) = 18.
The youngest brother has $18.
Given sides of length 300 mm or 190 mm, you can form 4 different triangles:
- equilateral with sides 190 mm
- equilateral with sides 300 mm
- isosceles with two sides 190 mm and one side 300 mm
- isosceles with two sides 300 mm and one side 190 mm
The triangle inequality requires the sum of the lengths of any two sides be not less than the length of the third side. Since 2×190 > 300, you can mix and match these side lengths any way you want. With three sides and 2 choices for each, there are only a limited number of possibilities.
In the above, we have not listed ones that are simply rotations or reflections of a congruent triangle. (A 190-190-300 triangle looks the same as a 190-300-190 triangle, for example.)

V = pi x r^ 2
H = pi x 13^2 x 28.6
Answer:
20.
Given, complex number is 10+5i .
We need to find sum of the given complex number and its conjugate. The conjugate of 10+5i is 10-5i. Therefore, the sum will be 10+5i+10−5i=20.
