−1.2(3x − 3) = 4(3x +0.9)

x = 0

Step-by-step explanation:

Solve for x:

-1.2 (3 x - 3) = 4 (3 x + 0.9)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the left hand side:

3.6 - 3.6 x = 4 (3 x + 0.9)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

3.6 - 3.6 x = 12 x + 3.6

Hint: | Move terms with x to the left hand side.

Subtract 12 x from both sides:

3.6 + (-3.6 x - 12 x) = (12 x - 12 x) + 3.6

Hint: | Combine like terms in -3.6 x - 12 x.

-3.6 x - 12 x = -15.6 x:

-15.6 x + 3.6 = (12 x - 12 x) + 3.6

Hint: | Look for the difference of two identical terms.

12 x - 12 x = 0:

3.6 - 15.6 x = 3.6

Hint: | Isolate terms with x to the left hand side.

Subtract 3.5999999999999996` from both sides:

(3.6 - 3.6) - 15.6 x = 3.6 - 3.6

Hint: | Look for the difference of two identical terms.

3.6 - 3.6 = 0:

-15.6 x = 3.6 - 3.6

Hint: | Look for the difference of two identical terms.

3.6 - 3.6 = 0:

-15.6 x = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -15.6 x = 0 by -15.6:

(-15.6 x)/(-15.6) = 0/(-15.6)

Hint: | Any nonzero number divided by itself is one.

(-15.6)/(-15.6) = 1:

x = 0/(-15.6)

Hint: | Zero divided by any non-zero number is zero.

0/(-15.6) = 0:

x = 0

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.

hope i could ! : )
