B. 1/27
1. you switch the denominator and the numerator (3/1 goes to 1/3).
2. then you take the exponents value (3) and put that as the exponent for 1/3
3. 1/(3^3) = 1/27
134.84 percent.
Just divide 384 by the other number
-2x-y=7
Add 2x to both sides
-y= 2x+7
Multiply both sides by-1
Y= -2x-7
2y=x+1
2(-2x-7)= x+1
-4x -14. =x+1
Add 14 to both sides
-4x=x +15
Subtract x from both sides
-5x=15
X=-3
2y =-3+1
-2y=-2
Y=1
(-3,1)
5:6 is your ratio because it says 5 and 6 and put them in the ratio.
12,5,13 are Pythagorean triplets..
so, missing side will be 12 inches
