3 + 2(2x + 8) = 1 is equivalent to:

x =

Step-by-step explanation:

=> 3+2(2x+8) = 1

=> 3+4x+16 = 1

=> 4x+19 = 1

=> 4x = 1-19

=> 4x = -18

Dividing both sides by 4

=> x =

=> x =

-9/2

Step-by-step explanation:

3 + 2(2x + 8) = 1

3 + 4x + 16 = 1

19 + 4x = 1

4x = -18

x = -18/4 = -9/2

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

answer: procent 54 wynosi 33,33%
