Solve for x: |3x + 12| = 18
Alla [95]

Answer:

X = 2 or X = -10

Step-by-step explanation:

We know either3x+12=18or3x+12=−18

3x+12=18(Possibility 1)

3x+12−12=18−12(Subtract 12 from both sides)

3x=6

3x

3

=

6

3

(Divide both sides by 3)

x=2

3x+12=−18(Possibility 2)

3x+12−12=−18−12(Subtract 12 from both sides)

3x=−30

3x

3

=

−30

3

(Divide both sides by 3)

x=−10

Answer:

x=2 or x=−10

. William fills 1/3 of a water bottle in 1/6 of a minute. How much time will it
Alex Ar [27]

Answer:

It will take him

\frac{1}{2}

of a minute to fill the bottle.

Step-by-step explanation:

I'm really not sure this is right but..

we can solve using proportions. Cross-multiply and divide.

\frac{ \frac{1}{3} of \: a \: water \: bottle}{\frac{1}{6} minute} \:  =  \frac{ \frac{3}{3} of \: a \: water \: bottle}{x}  \\  \\  \frac{ \frac{1}{6} }{ \frac{1}{3} }  =  \frac{ \frac{1}{3} x}{ \frac{1}{3} }  \\  \\  \frac{1}{2}  = x
