HELP I'm very bad at story questions lolol
Mila [183]

1ST  Piece  =======>    2x ======>  2  *   3 ft.  ======>   6 ft.

2ND  =========>    5x        =======>    5  *  3 ft.   ======>  15 ft.

3RD  ==========> 4 Feet     =======> 4 ft.

Sum  ======>    25 Feet



Equation:

(2x    +    5x)       +     (4)       =        25


Let's solve your equation step-by-step.

2x       +      5x      +      4     =       25

Step 1: Simplify both sides of the equation.

2x       +         5x       +       4       =      25

(2x      +      5x)         +         (4)       =     25         (Combine Like Terms)

7x       +      4      =       25

7x        +      4       =     25

Step 2: Subtract 4 from both sides.

7x       +      4       −       4      =     25     −    4

7x     =      21

Step 3: Divide both sides by 7.

7x / 7       =         21 / 7

Answer ========>          x        =         3




Check:

(2x    +    5x)       +     (4)       =        25

2(3)   =    6

5(3)    =   15

3rd  Piece  =    4

Sum  =      25

6ft.    +      15ft.       +      4ft       =     25

25             =                    25




Hope that helps!!!!!!!!!!!!!                                              : )
