Solve for x: 3x = 54

Answers

The calculated value of x in the equtaion 3x = 54 is 18

How to calculate the value of x in the equtaion

From the question, we have the following parameters that can be used in our computation:

3x = 54

Divide through the equation by 3

so, we have the following representation

3x/3 = 54/3

Evaluate the quotient on the right hand side

3x/3 = 18

Lastly, we have

x = 18

Hence, the value of x in the equtaion is 18

You can divide 3 by itself to cancel itself out. 
Now, keep it even and divide 3 from 54.
54/3 = 18.

x = 18.

The GCF of any two even numbers is always even. Determine whether the statement is true or false. If true, explain why. If false, give a reason.

Answers

The question is asking us whether it is true that The GCF of any two even numbers is always even. GDF means the greatest common factor, for example the GCF of 24 and 32 is 8 - it's the biggest of their factors. The GCF is a multiple of all the (prime) common factors, and 2 is a common factor of two even numbers, so GCF will always be even - this is true!
It is true that the GCF of any two even numbers is always even. GCF refers to the greatest common factor that two or more numbers have, and obviously it is going to be an even number. Take 18, 30, and 42 as your example - their GCF will be 6, which is an even number, as are those three numbers. GCF of odd numbers will be odd, and GCF of an odd and even number is also always even.

Answer:

F 1/36

Step-by-step explanation:

There are 3+5+10 = 18 markers in the drawer

P (green) = green/total =3/18 = 1/6

P( green,green) = P(green) * P (green)

                          = 1/6* 1/6 = 1/36

Getting 2 greens in a row with replacement is 1/36

Which of the following is the solution to 9|x+4|>54 ?

Answers

Answer:

x < -10, x > 2

Step-by-step explanation:

9|x+4| > 54

|x+4| > 6

Split the absolute value into two equation, positive and negative.

1.)POSITIVE

x+4 > 6

x > 2

2.)NEGATIVE

-(x+4) > 6

-x - 4 > 6

-x > 10

x < -10

Answer:

\large\boxed{x<-10\ \vee\ x>2\to x\in(-\infty,\ -10)\ \cup\ (2,\ \infty)}

Step-by-step explanation:

9|x+4|>54\qquad\text{divide both sides by 9}\n\n(9|x+4|)/(9)>(54)/(9)\n\n|x+4|>6\iff x+4>6\ \vee\ x+4<-6\n\nx+4>6\qquad\text{subtract 4 from both sides}\n\nx+4-4>6-4\n\nx>2\n\nx+4<-6\qquad\text{subtract 4 from both sides}\n\nx+4-4<-6-4\n\nx<-10

Dave wants to install carpet in his room. The room is rectangular in shape with a length of 16 feet and a width of 12 feet. If the total cost of installing the carpet is $288, what is the unit price of carpet per square foot?

Answers

Hello there!

If you multiply 12 by 16, you get 192. Divide 288 by 192 ( being the total amount of square feet. ) and you get 1.5, essentially being $1.50 per square foot.

To check this, multiply 192 by 1.5 and you will get 288.
Ok so the width is 12 and the length is 16 so we will multiply those:         12 x 16=192 so now we divide 288 by 192= 1.5 or %1.50 so the answer is %1.50 per square foot              Hope this helped!!
