artcher [175]

Solution :

1st -

$- 3 \times 5 \times ( - 6) \times 4$
$- 15 \times (- 6) \times 4$
$90 \times 4$
$360$

2nd -

$- 4 \times ( - 6 )\times ( - 3) \times ( - 5)$
$24 \times ( - 3) \times ( - 5)$
$- 72 \times ( - 5)$
$360$

3rd -

$- 3 \times 4 \times ( - 2) \times ( - 7)$
$- 12 \times ( - 2) \times ( - 7)$
$24 \times ( - 7)$
$- 168$

4th -

$- 7 \times ( - 3) \times ( - 9) \times 0$
$21 \times ( - 9) \times 0$
$- 189 \times 0$

If 3t-7=5t, then 6t =

Natalija [7]

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 " .
