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.

Answer:
A rational number.
Step-by-step explanation
A rational number is a ratio of whole numbers.
1/3 is the ratio of 1:3
3:1 becomes 3/1 = 3
32:10 can be written 32/10 or 16/5 or 3.2
16/5 is a rational number 16 and 5 are integers, 5 is not equal to 0.
Therefore, 3.2 which can be expressed as 16/5 is a rational number.
Answer:
f(x)=(x-2)(x+2)(x-5)
Step-by-step explanation:
f(x)=x³-5x²+4x-20 1. Just group randomly
f(x)=x²(x-5)+4(x-5) 2. Factor the groupings
f(x)=(x²+4)(x-5)
<u>f(x)=(x-2)(x+2)(x-5)</u> 3. Factor the difference of two squares
Substitute the 7 in anywhere there is an x.
49-5=44
