Answer: 17%
Step-by-step explanation:
136,890-117,000=19,890
19,890/117,000=0.17
0.17*100=17% increase in the city population
16) you are right
3x-4=2x+6
x=10
17)
1st segment = x
2nd segment = 2x
3d segment = 4x+3
equation x+2x+4x+3=38
7x = 38-3
7x=35
x=5
First segemnt = 5 inch
2nd segment 2x = 2*5 = 10 inch
3d segemnt 4x+3=4*5+3=23 inch

Answer:
350
Step-by-step explanation:
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
120% = 120/100 = 120 ÷ 100 = 1.2
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 120% of what number = 420?
120% × ? = 420
? =
420 ÷ 120% =
420 ÷ (120 ÷ 100) =
(100 × 420) ÷ 120 =
42,000 ÷ 120 =
350
<h2>Proof</h2><h3>How do we check the result?</h3>
If 120% × 350 = 420 =>
Divide 420 by 350...
... And see if we get as a result: 120%
<h3>Note:</h3>
Multiply a number by the fraction 100/100,
... and its value doesn't change.
100/100 = 100 ÷ 100 = 1
n/100 = n%, any number.
