The answer is:  " -21 " .
__________________________________________
We are asked to solve for: "6t" ; which is: "6 * t" .
__________________________________________
Given:  3t − 7 = 5t ;  Solve for "t" ; then solve for "6t" ;

     3t − 7 = 5t ;   Subtract "3t" from each side of the equation;
____________________________________________
    3t − 7 − 3t  =  5t − 3t ;

to get:  -7  = 2t  ;

Divide EACH side of the equation by "2" ; to isolate "t" on one side of the equation; and to solve for "t" ;

-7/2 = 2t / 2 ;

-3.5 = t  ;  ↔  t = - 3.5 ;
____________________________________________
Now, solve for "6t" ;

  6 t = 6*(-3.5) = - 21 .   The answer is:  " -21 " .

Is trapezoid ABDC the result of a dilation of trapezoid MNPQ by a scale factor of ? Why or why not?
Nady [450]

Answer:

No, because AB is 2/5 the length MN but CD is 1/3 the length QP.  

Step-by-step explanation:

Comparing the corresponding sides, the length of AB is 4.  The length of MN is 10.  This makes their ratio 4/10 = 2/5.

The length of CD is 2.  The length of QP is 6.  this makes their ratio 2/6 = 1/3.

The ratios of the sides are not the same, so the figure is not proportional and is therefore not a dilation.
