Answer:
BD = 3.75 units
Step-by-step explanation:
Given AD is an angle bisector then it divides the opposite side into segments tat are proportional to the other 2 sides, that is
= 
, substitute values
= 
( cross- multiply )
8 BD = 30 ( divide both sides by 8 )
BD = 3.75 units
Answer:
$23.646
Step-by-step explanation:
325.80 times 0.07 equals 22.806
12 times 0.07 equals 0.84

Answer:
x = -11 and y= -8 is the solution to the system
Step-by-step explanation:
Given:
x - 2y = 5 let it be equation (i)
-x + y = 3 let it be equation (ii)
To find:
x = ?
y = ?
Solution:
The equations are given to us from which we are supposed to find the values of x and y
Taking first equation which is
x - 2y = 5
adding 2y on both sides
x - 2 y + 2y = 5 + 2y
x = 5 +2y ............................(iii)
Now putting this value in equation (ii)
which is
-x + y = 3
Putting value gives
-(5 + 2y) + y = 3
-5 -2y+y = 3
-5 - y = 3
adding 5 on both sides
-5 -y + 5 = 3 + 5
-y = 8
Multiplying both sides by (-1)
-y(-1) = 8 * (-1)
y = -8
Now we have equation (iii) which is
x = 5 + 2y
putting the value of y in it
x = 5 + 2*(-8)
x = 5 -16
x = -11
so the solution to the system is
x = -11 and y= -8
Answer:
That is 6 divided by 3/8, better written as

1 3
Reduce 6/3: 6/3 = 2
Then you have 2(8), or 16 (answer)
