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
3[x + 3(4x - 5)] = 15x - 24
3(x + 12x - 15) = 15x - 24
3(13x - 15) = 15x - 24
39x - 45 = 15x - 24 |add 45 to both sides
39x = 15x + 21 |subtract 15x from both sides
24x = 21 |divide both sides by 24
x = 21/24
x = 7/8

The answer is
<h2>

</h2>
Step-by-step explanation:

To find f(-4) , substitute the value of x that's - 4 into f(x). That is for every x in f(x) , replace it with - 4

Got it on Khan Academy, math geeks.
Congrats. Now you got a free cheater's answer in Quadratic Word Problems (vertex form). Your welcome, cause I got it wrong.
Don't mind my attitude. TRUST ME AND YOU WON'T REGRET IT.
:P
PLEASE MARK BRAINLIEST AND THANKS. THANK YOU SO MUCH!
Answer:
Quadrilateral ABCD is inscribed in a circle, then
A + C = 180
=> 2x + 9 + 3x + 1 = 180
=> 5x = 170
=> x = 34
=> A = 2 x 34 + 9 = 77 deg
Hope this helps!
