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 .Reply
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 = 132x = 22x = 11Hope this helps!Reply
let x be the number:4 times a number = 4xThen 3 more than 4x:=4x+3Twice the number = 2xThen 8 less than twice the number:=2x-9 Write the equation:4x+3=2x-9Subratact 2x form both sides:2x+3= -9Subtract 3 form both sides:2x = -12Divide both side by 2:x = -6Next, check your4x + 3 = 2x - 9Substitute -6 for x:4(-6) + 3 = 2(-6) - 9Mulitiply:-24 + 3 = -12 - 9Add:-21 = -21And now you know you answer is -6!Hope this helps! 🙂Reply
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 hoursThe number of hours Sophia worked = 2 ( Hours Cody worked) - 9= 2 ( 16) - 9 = 23 hoursNow, for working 16 hours,Cody earned = $156.80So, 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) = $225.4Hence, after working for 23 hours in grocery store, Sophia made $225.4.Reply
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
