Solve for x. -4(-2x - 2) + x - 2 = -48

x = -5.7778

Step-by-step explanation:

1)  8x + 8 + x -2 = 48 (You multiply the -4 into both -2x and -2, thus getting rid of the brackets)

2) 9x + 6 = -48 (Add the two values of x (8x + x) and then subtract the 2 from 8  = 6)

3) 9x =-46 - 6 (Move the 6 mover, which will change its sign from a (+) to a (-6))

4) 9x = -52 (Do the expression, and you get -52)

5) x = -52 / 9 (Isolate the x, by dividing both sides by it)

6) x = -5.7778 (Round the answer)

28

step-by-step explanation:

8+8+6+6

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
