Answer:
12.1072
Step-by-step explanation:
  5.264
 x                           take 3 multiply with 5264 = 15792
       2.3                 then take 2 multiply with 5264 = 10528 
  15792                  add column by column as drop 2 down, then 9 + 8 
10528                    then 7+2, 5+5, 1+0, 1. then count how many numbers total 
 121072                  behind the point  .264= 3 numbers + .3 is 1 number= 4#s
                                then count backward the result 4 numbers 2701 put the                         
                                dot there you will get 12.1072
 
        
             
        
        
        
Answer:
15 feets 
Step-by-step explanation:
The perimeter of a parallelogram is given as :
P = 2(l + w)
l and w are the bases :
Substituting the values into the equation :
P = 2(x + 75 + x + 45)
P = 2(2x + 120)
P = 300
Hence ;
300 = 4x + 240
300 - 240 = 4x
60 = 4x
Divide both sides by 4 to isolate x
60 /4 = 4x / 4
15 = x
x = 15 feets 
 
        
             
        
        
        
Answer:
i think probably 80°
Step-by-step explanation:
PQ = RS
2x+3 = 4x-3
x = 3
PTQ = RTS
9y-3x-1 = 5x+7y-5
2y-8x = -4
y-4x = -2
y-4(3) = -2
y-12 = -2
y = -2+12
y = 10
so PTQ = 9y-3x-1 
9(10)-3(3)-1
90-9-1
80°
 
        
             
        
        
        
Here is the math, did it on paper, sorry it’s blue. just add parenthesis around the x in the second equation and add what x equals. then solve as PEMDAS.
 
        
        
        
Answer: 
54 
Step-by-step explanation: 
4^3-4/2*5 
4^3=64 
64-4/2*5 
-4/2=-2 
64-2*5 
-2*5=-10 
64-10=54 
Parenthesis 
Exponent 
Multiply or Divide (whichever comes first) 
Add or Subtract (whichever comes first) 
Hope this helps
