Three boards are placed end to end to make a walkway. The first board is 4 feet inches 10 long, the second board is 2 feet 11 in
Strike441 [17]

Answer:

12 ft 2 in.

Step-by-step explanation:

Conversion: 1 ft = 12 in.

Add the lengths of the boards.

4 ft 10 in. + 2 ft 11 in. + 4 ft 5 in. =

= 4 ft + 2 ft + 4 ft + 10 in. + 11 in. + 5 in.

= 10 ft + 26 in.

= 10 ft + 24 in. + 2 in.

Since 1 ft = 12 in., then 24 in. = 2 ft.

= 10 ft + 2 ft  + 2 in.

= 12 ft 2 in.

The figure is a parallelogram.
slavikrds [6]
Answer:  " m∠ACD = 40° " .
______________________________________________________
Explanation:
______________________________________________________
We are asked to find:  "m∠ACD" ; 
______________________________________
Note:  m∠ACD  =  m∠ABD ; 
______________________________________________________
So, given: 

m∠ACD  =  (4x + 4)° ;

m∠ABD =   <span>(6x - 14)° ;
_______________________________________________________
  4x + 4 = 6x - 14 ;

Solve for "x" ; then solve for:  "m</span>∠ACD"  ;
_______________________________________________________
 Add "14" to each side of the equation; and subtract "4x" from each side of the equation ; 

  4x + 4 + 14 - 4x  = 6x - 14 + 14 - 4x  ;

to get:

18 = 2x ;

↔  2x = 18 ;

Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; & to solve for "x" ;
__________________________________________________________
     2x / 2 = 18/2 ;

      x = 9 .
_________________________________________________________
Now, to solve for:  " m<span>∠ACD "  :
</span>_________________________________________________________
      m∠ACD =  <span>(4x + 4)°  ;

Substitute "9" for "x" ; 
</span>
      m∠ACD = (4*9) + 4 = 36 + 4 = 40° .
_____________________________________________
Answer:  " m∠ACD = 40° " .
_____________________________________________
Let us check our answer:
_____________________________________________
m∠ACD = 40 ; and m<span>∠ABD = (6x - 14) ;

</span>m∠ACD = ∠ABD ; 
<span>
Since </span>m∠ABD = (6x - 14) ;  

If x = 9;  if we plug in "9" into the expression for "m∠ABD" ; will the value obtained be "40" ??

m∠ABD = (6x - 14) ;  Let us plug in "9" for "x" ; to see if the value obtained is "40"

6x - 14 = ? (6*9) - 14 ??
 
6x - 14 = ?  54 - 14 ??

6x - 14 = ? 40 ?? Yes!
