What is 15 - 1/6n = 1/6n - 1

Answers

Answer 1

Answer: 15-1/6n=1/6n-1
15+1=1/6n+1/6n
16=1+1/6n
16=2/6n
16=1/3n
16*3/1=n
therefore, n=48.........

Answer 2

Answer:

Answer:

n=48

Answers

Congruence transformation results to a perimeter of any polygon that is the same as the original dimensions and shape. In this case, this is similar to translation where all dimensions, angles are retained constant. The answer to this problem hence is B

Answer:the same as

Choose the correct graph of the given system of equations.y + 2x = −1
3y − x = 4

graph of two lines that intersect at the point (negative 1, 1)
graph of two lines that intersect at the point (1, 1) < Not
graph of two parallel lines with positive slopes
None of the above

Answers

Answer: Graph of two lines that intersect at the point (negative 1, 1).

Step-by-step explanation:

The given system of linear equations :

$y+2x=-1---------(1)\n\n3y-x=4-------------(2)$

Multiply equation (1) by 3 , we get

$3y+6x=-3-------------(3)$

Subtract equation (2) from (3), we get

$6x+x=-3-4\n\n 7x=-7$

Divide both sides by 7 , we get

x=-1

Put value of x in (1), we get

$y+2(-1)=-1\n\n y-2=-1\n\n y=-1+2=1$

⇒ both lines are intersecting at (x,y)=(-1,1)

∴ The correct graph of the given system of equations : graph of two lines that intersect at the point (negative 1, 1)

Answer:

(-1,1) One solution

Step-by-step explanation:

Use these steps for the equations:

1) Rewrite the equation in slope intercept form.

2) Graph the first equation.

3) Graph the second equation.

4) Identify the point of intersection.

What is the length of the side of a square field whose perimeter is 72 mº.

Answers

Answer:

18 meters

Step-by-step explanation:

"Perimeter" is all 4 sides added together, right?

Since it's a square, all four sides are equal, so the problem looks like this:

s + s + s + s = 72 where s = side length

Before doing any math, can you think of a number that you could add to itself 4 times and get 72? If not, you get to do some algebra:

s + s + s + s = 72 reduces to:

4s = 72 Then solve for s:

s = 72/4 = 18 m

Check your work by seeing if 4 x 18 = 72. It does, so the answer is correct.
