Solve for 9 less than twice a number is 25

Its B

Step-by-step explanation:

Twice a number = 2n

Then you subtract 9

2n - 9

11

Step-by-step explanation:

The answer is: 17 .

Explanation:

2x - 9 = 25 ;

Add "9" to each side of the equation;

2x - 9 + 9 = 25 + 9 ; to get:

2x = 34 ;

Now, divide EACH SIDE of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ;

2x / 2 = 34 / 2 ;

x = 17 .

x = 11.

Step-by-step explanation:

9 less than twice a number is the same thing as twice a number minus 9. Let's say that the number is x.

2x - 9 = 13

2x = 22

x = 11

Hope this helps!

let x be the number:

4 times a number = 4x

Then 3 more than 4x:

=4x+3

Twice the number = 2x

Then 8 less than twice the number:

=2x-9

Write the equation:

4x+3=2x-9

Subratact 2x form both sides:

2x+3= -9

Subtract 3 form both sides:

2x = -12

Divide both side by 2:

x = -6

Next, check your

4x + 3 = 2x - 9

Substitute -6 for x:

4(-6) + 3 = 2(-6) - 9

Mulitiply:

-24 + 3 = -12 - 9

Add:

-21 = -21

And now you know you answer is -6!

Hope this helps! 🙂

4x=-9+2

Step-by-step explanation:

I think thats the expression

It would be A. 9-2n. I Hope this helped.

After working for 23 hours in grocery store, Sophia made $225.4.

Step-by-step explanation:

The number of hours Cody worked at grocery store = 16 hours

The number of hours Sophia worked = 2 ( Hours Cody worked) - 9

= 2 ( 16) - 9 = 23 hours

Now, for working 16 hours,Cody earned = $156.80

So, the per hour earning of Cody = [tex]\frac{\textrm{Total payment he received for 16 hours}}{\textrm{16 hours}}[/tex]

=[tex]\frac{156.80}{16} = 9.8[/tex]

or, the hour earning of Cody = $9.8

⇒Now as Sophia has same hourly rare, so she earns $9.8 per hour.

So, total earning after working for 23 hours = 23 x ( Earning per hour)

= 23 x ($9.8) = $225.4

Hence, after working for 23 hours in grocery store, Sophia made $225.4.

2n-9

Step-by-step explanation:

Ok so what is 2 times 25...

50

and 50 - 9 is 41

So 41 is our answer
