Christina used 21 centimeters of tape to wrap 3 presents. How much tape will Christina need in all if she has to wrap 5 presents? Solve using unit rates.

35 cm

Step-by-step explanation:

(21/3)(5) = 35 cm

21 cm/3 presents = 7 cm per present

7 cm x 5 presents = 5 cm

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  

                    x-10-(44)=0  

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

1.1      Solve  :    x-54 = 0  

Add  54  to both sides of the equation :  

                     x = 54  

One solution was found :

 x = 54
