Answer:

x = 4

Step-by-step explanation:

4(3x - 10) + 7 = 15

multiply 3x and 10 by 4

12x - 40 + 7 = 15

add 40 both sides

12x + 7 = 55

subtract 7 from both sides

12x = 48

divide

x = 4

hope this helps :)

Help meeeeeeeeeeee:(
Vaselesa [24]

Answer:

1/3

Step-by-step explanation:

(1/3)^2x(1/3)^-1

so, we can write this as:

1/3 x 1/3 x 3/1

if calculated by cutting, the answer is 1/3

There is also an easier way to do this,

(1/3)^2 x (1/3)^-1

as the bases are same, the powers will be added.

2+(-1)

2-1

=1

so,

(1/3)^1 or 1/3
