Answer:
u  = - ( 9-6w)/2
Step-by-step explanation:
to  evaluate for u in the expression -2u+6w=9 is simply to look for a way such that we would express u in terms of w and other variables.
solution
-2u+6w=9
-2u = 9 - 6w
divide both sides by the coefficient of u which is -2
-2u/u = 9 - 6w/-2
u  = - ( 9-6w)/2
therefore the value of u when rearranged in the equation -2u+6w=9 is evaluated to be equals to
u  = - ( 9-6w)/2
 
        
             
        
        
        
Hey there! :D
When you write out decimals, you use words that end with 'ths'. And you use the smallest digit's place to name the whole decimal. 
For example,
.1 = one-tenths  .25= twenty hundreths .345= three hundred and forty five thousandths
9.753= Nine and seven hundred fifty-three thousandths. 
I hope this helps!

Answer:
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
Step-by-step explanation:
let assume that stick has length 1.Random variable L that make length of a longer piece and random variable U that mark point .See that L < l means that 
U≤ l and 1-U ≤l
P(L ≤ l) =P (1-l ≤ U ≤ l)= l- ( 1 - l ) = 2 l - 1
this means 1-l≤U≤l 
so we have
if we have L  [1/2,1]
then apply the formula we have E(L)=3/4
 
        
             
        
        
        
Answer:
-17
Step-by-step explanation:
 - 5 * (6 + 4) ÷ 2
 - 5 * (6 + 4) ÷ 2
Following PEMDAS, we must focus on the parenthesis first.
 - 5 * (6 + 4) ÷ 2
 - 5 * (6 + 4) ÷ 2
 - 5 * (10) ÷ 2
 - 5 * (10) ÷ 2
Now we will focus on the exponent:
 - 5 * 10 ÷ 2
 - 5 * 10 ÷ 2
8 - 5 * 10 ÷ 2
Now Multiplication/Division.
This is where you must follow the order in the equation where you see the multiplication sign first, so you multiply first. 
8 - 5 * 10 ÷ 2
8 - 50 ÷ 2
Next, Divide:
8 - 50 ÷ 2
8 - 25
Subtract:
8 - 25 
-17
 - 5 * (6 + 4) ÷ 2 = -17.
 - 5 * (6 + 4) ÷ 2 = -17.
