Answer:
1875 square miles
Step-by-step explanation:
There are a total of 10 women and 3 men. Let's define two variables:
- w: land inherited by a woman
- m: land inherited by a man
Given that they inherited a 30000 (square miles) of land and that each brother has inherited double what each sister has inherited, we can establish the next equations:
2*w = m
10*w + 3*m = 30000
Replacing the first equation into the second one, and solving for w:
10*w + 3*2*w = 30000
16*w = 30000
w = 30000/16
w = 1875 square miles
Your mom, and all of her sisters, inherited 1875 square miles each
We have that
<span>observing the graph of the problem, it is evident that the solution is option D, since the graph of the parabola presents a domain for x <4 and the line presents a domain for x> = 4 and the only option with these two conditions is option D
</span>
using a graph tool
<span>I proceed to verify</span>
see the attached figure
the answer is the option D
Iam not sure for the awnser but maybe its 3
You could make the numbers have a common denominator.
-3/7 --> -9/21
-2/3 --> -14/21
|-14/21| - |-9/21| = 5/21 difference.
5/21 is the distance.
