3^(x−1) = 27<br> please and thank you in advance

notka56 [123]

Answer: $x = 4$

Step-by-step explanation:

Given :

$3^{x-1} = 27$

27 can also be written in index form , so the equation becomes

$3^{x-1} = 3^{3}$

since they have the same base , we will equate their power , that is

$x - 1 = 3$

$x = 4$

The sides of a triangle are in the extended ratio 2 colon 6 colon 7. If the perimeter of the triangle is 45 inches, then what is

allsm [11]

Ratio : 2:6:7....for a total of 15. This means that one side is 2/15 of the total perimeter, one side is 6/15 of the total perimeter and one side is 7/15 of the total perimeter.

and if the total perimeter is 45 inches...
2/15 * 45 = 90/15 = 6 inches
6/15 * 45 = 270/15 = 18 inches
7/15 * 45 = 315/15 = 21 inches

and the shortest side is gonna be 6 inches <==
