What is the solution to 6x=30
Tasya [4]

Answer:

\boxed{x=5}

Step-by-step explanation:

Division property of equality- is dividing both sides of an equation by the same non-zero number it does not change the equation.

First you had to divide by six from both sides of an equation form.

\frac{6x}{6}= \frac{30}{6}

30/6=5

30/5=6

5*6=30

6*5=30

x=5

5=x

Final answer: \boxed{x=5}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

What is the slope of the line represented by the equation 2x+3y= –12 ? –32 –23 23 32
mr_godi [17]

Answer:

Option 2 - m=-\frac{2}{3} is the slope of the equation.

Step-by-step explanation:

Given : Equation 2x+3y=-12

To find : What is the slope of the line represented by the equation ?

Solution :

The slope form of line is y=mx+c

Equation 2x+3y=-12

Take 2x to another side,

3y=-12-2x

Divide 3 both side,

y=\frac{-12-2x}{3}

y=\frac{-2}{3}x-4

On comparing with general equation,

m=-\frac{2}{3} is the slope of the equation.

Therefore, option 2 is correct.

Black Diamond Ski Resort charges $50 for ski rental and $15 an hour to ski. Bunny Hill Ski Resort charges $75 for ski rental and
andrew11 [14]

Answer:

The cost of 5 hours of skiing would be the same ($125) after 5 hours.

Step-by-step explanation:

Black Diamond:  ChargeBD(h) = $50 + ($15/hr)h, where h is the number of hours spent skiing.

Bunny Hill:  ChargeBH(h) = $75 + ($10/hr)h

We equate these two formulas to determine when the cost of using the ski slopes is the same:

ChargeBD(h) = $50 + ($15/hr)h = ChargeBH(h) = $75 + ($10/hr)h

We must now solve for h, the number of hours spent skiing:

50 + 15h = 75 + 10h

Grouping like terms, we obtain:

5h = 25, and so h = 5 hours.

The cost of 5 hours of skiing would be the same ($125) after 5 hours.

Evaluate the series 9 + 3 + 1 +
ryzh [129]

Answer:

9 + 3 + 1 + ......... = 13.5

Step-by-step explanation:

The series 9 + 3 + 1 +  is the sum of an infinite geometric sequence. The first term of the series is 9 while the common ratio is 1/3;

to obtain the common ratio we obtain the quotient of any two successive terms, 3/9 or 1/3.

The sum of an infinite geometric series with first term a and common ratio r is given by;

S_{n}=\frac{a}{1-r}

Plug in the values of a and r into the formula;

S_{n}=\frac{9}{1-\frac{1}{3} }\\\\\\S_{n}=\frac{27}{2}=13.5
