Answer:
13, 587 times
Step-by-step explanation:
Population of City A
= 1.9 * 105 = 157.5
Population of City B
= 1,070,000
Population of City C
= 2 * city B
= 2 * 1,070,000
= 2,140,000
The population of City C is how many times the population of City A?
City C = x * City A
2,140,000 = x * 157.5
x = 2,140,000 / 157.5
x = 13587.30
The population of City C is 13587.30 times the population of City A.
Hope this helps :)
Answer:
x=-10
Step-by-step explanation:
4.5(8-x)+36=102-2.5(3x+24) first you multiply 10 to both sides
4.5(8-x)x10+36x10=102x10-2.5(3x+24)x10
Then you have to refine the equation
45(8-x)+360=1020-25(3x+24)
Then you expand it
45(8-x)+360
=360-45x+360
Simplify
360-45x+360 -45x+720
Expand it one more time
-45x+720=-75x+420
Subtract 720 from each side
-45x+720-720=-75x+420-720
Simplify
-45x=-75x-300
Add 75x to both sides
-45x+75x=-75x-300+75x
Simplify
Divide both sides by 30
30x/30=-300/30
Then you get -10
13/100 would be it because you divide it over 100
I have recently learned how to do this...
The method goes...
K H D _ d c m
i e e u e e i
l c c n c n l
o t a i i t l
a t i i
Meaning... that to convert it from kilograms to grams you will move the decimal point backwards three.
