Answer:4000
Step-by-step explanation:
Let them number be a
655% of a=26200
655/100 x a=26200
655a/100=26200
Cross multiplying we get
655a=26200x100
655a=2620000
Divide both sides by 655
655a/655 = 2620000/655
a=4000

Okay, these get easy with practice so don't post all of these online. First, substitute y in 3x-2y=9 for what it says y equals (2x-7). You now have: 3x-2(2x-7)=9. Breakdown:
3x-2(2x-7)=9
3x-4x+14=9
-1x=-5
x=5
next solve for y
y=2x-7
y=2(5)-7
y=10-7
y=3
And now we have x=5, and y=3.
The correct answer is 2/5 because it is the simplest form of 16/40. Hope this helps.
