Parvinis older than Jan, who is

1 answer:

8 0

Using the arrangements formula, it is found that there are 24 ways for them to stand in line so that the youngest person is always first, and the oldest person is always last.

<h3>What is the arrangements formula?</h3>

The number of possible arrangements of n elements is given by the factorial of n, that is:

$A_n = n!$

In this problem, we have that there are 6 people. The youngest person(Leslie) has to be first, while the oldest(Parvinis) has to be last, while the remaining 4 can be arranged, hence the number of ways for them to stand in line is given by:

$A_4 = 4! = 24$

If x + 2/7x = 9, then x=

Zigmanuir [339]

Answer: " x = 7 " .

__________________________________________

Step-by-step explanation:

__________________________________________

Given:

x + (2/7)x = 9 ; Solve for "x" ;

Note:

Start by simplifying the "left hand side of the equation:

$x +\frac{2}{7}x =1x +\frac{2}{7}x =$ $(1\frac{2}{7}) x =\frac{(7*1)+2}{7}x = \frac{(7+2)}{7}x = \frac{9}{7}x$ ;

__________________________________________

Now, rewrite the equation:

__________________________________________

$\frac{9}{7}x =9$ ; Solve for "x" ;

We now multiply each side of the equation by "7" ;

to get rid of the "denominator" within the "fraction value"

on the "left-hand side" of the equation:

$7 *\frac{9}{7}x = 9 * 7$ ;

On the "left-hand side" of the equation:

The "7's" cancel out to "1's" ; since "7÷7 = 1 " ;

And we are left with "9x" on the "left-hand side" of the equation.

On the "right-hand side" on the equation; we find that: "9 * 7 = 63 ."

So; we can rewrite the equation:

9x = 63 ;

To solve for "x" ; we divide each side of the equation by: "9" ;

to isolate "x" on one side of the equation;

& to solve for "x" ;

9x / 9 = 63 / 9 ;

to get:

x = 7 .

Find X. 2x + 15 = 20

lakkis [162]

Answer:

x = 5/2 or x = 2.5

Step-by-step explanation:

To solve for x, we will have to get the equation 2x + 15 = 20 into the form x = _. That will be our answer.

2x + 15 = 20

Subtract 15 from both sides to get rid of the +15 on the left side.

2x = 20 - 15

Simplify.

2x = 5

Divide both sides by 2 to get rid of the coefficient of 2 on the left side.\

x = 5/2 = 2.5

x = 5/2 or x = 2.5

I hope you find my answer helpful. :)
