4+4v = 3v +4
------- = -----------
-3 2
use cross products
(4+4v) *2 = -3*(3v+4)
distribute
8+8v = -9v-12
add 9v to each side
8+17v = -12
subtract 8 from each side
17v = -20
divide by 17
v = -20/17
(4 + 4v)/-3 = (3v + 4)/2
In order to solve this, we need to make the denominators equal.
Multiply both sides of the first equation by 2.
2(4 + 4v)/-6
Now, multiply both sides of the second equation by -3.
-3(3v + 4)/-6
Now, focus on the numerators. We're left with:
2(4 + 4v) = -3(3v + 4)
Distributive property.
8 + 8v = -9v - 12
Subtract 8 from both sides.
8v = -9v - 20
Add 9v to both sides.
17v = -20
Divide both sides by 17
<h3><u>v = -20/17</u></h3>

Answer:
B: 43.3
Step-by-step explanation:
The sum of the 3 angles in a triangle is 180 , from the name you can know that it will have 3 equal angles which will be 60 degrees each as 180÷3=60
12 is 75% of what
is means equals, of means multiply
12 = 75% * what
12 = .75 * what
divide each side by .75
12/.75 = .75 * what /.75
16 = what
12 is 75 percent of 16
the answer is 16
