Answer:

x=4

Step-by-step explanation:

18 = 3(3x − 6)

Divide each side by 3

18/3 = 3( 3x-6)/3

6 = 3x-6

Add 6 to each side

6+6 = 3x-6+6

12 = 3x

Divide by 3

12/3 = 3x/3

4 =x

Answer: 4 = x

Step-by-step explanation: To solve this equation, we start by

distributing the 3 through the parenthses on the right side.

3(3x) is 9x and 3(-6) is -18.

So our equation now reads 18 = 9x - 18.

Our next step is to get the x term by itself on the right side.

So we add 18 to both sides to get 36 = 9x.

Now divide both sides by 9 to get 4 = x.

4 people can stay in a hotel for 5 days for $ 240. Find the bill for 5 people staying in
Lemur [1.5K]

Answer:

$420

Step-by-step explanation:

Divide to isolate the cost

240 / 4 = 60 - amount per person (for 4 people)

60 / 5 = <u>12</u> - amount per person per day (5 days)

Multiply using that cost and new values.

12 x 5 = 60

60 x 7 = 420

How do I solve this?
IrinaK [193]

Answer:

m∠NPM = 101°

Step-by-step explanation:

Since a straight line has an angle of 180°, we can just subtract 79° from 180° to find the measure of ∠NPM

180 - 79 = 101°

∠NPM = 101°

67 hundreds into standard form
Svetach [21]

There's a difference between "hundredths" and "hundreds". I'm going to assume you mean 6,700.

Answer:

6.7*10^3

Step-by-step explanation:

Write out the number.

6700

Bring the decimal to the left. However many times you move over to the left until you get between 6 & 7 should be your exponent for 10.

6.7*10^3

I Need The Answer Please Help!!
mariarad [96]

Answer:

33°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 given angles from 180 for ∠1, that is

∠1 = 180° - (116 + 31)° = 180° - 147° = 33°
