50x+40=y for doors galore

40x+60=y for g&h

I can't graph here sorry but hopefully you know how that works

9. 40x+60=50x+40

-40

40x+20=50x

-40x

10x=20

x=2

10. Doors galore because 1 hours equates to 90 while g&h is 100 and so 90>100 then Doors galore is cheaper

thank you & if this helped pls don't forget to give brainiest

PIT_PIT [208]

Answer:

23958, 23598, 25938, 25398, 29358, 29538....

Step-by-step explanation:

We have given the number cards for for 2 3 8 9 and 5. We have to find the different  ways Nia can arrange the cards to show only even numbers with the 2 in the ten thousands place.

The number should be even numbers with two in the ten-thousand places.

Only 8 is left as an even number. So 8 would be at the one's place.

In the ten-thousand places, arrange the three digits 3,9 and 5 in the middle.

So there are 3*2=6 ways to arrange the  middle three digits in the ten-thousand places.  

23958, 23598, 25938, 25398, 29358, 29538....
