Answer:
16 years
Step-by-step explanation:
Let x represent the number of years. The suburb population is growing at a rate of 5000 per year after x years, it can be represented by the equation:
320000 + 5000x
The city population is declining at a rate of 14000 per year after x years, it can be represented by the equation:
624000 - 14000x
The number of years for the city and suburb population to be equal can be gotten from:
320000 + 5000x = 624000 - 14000x
14000x + 5000x = 624000 - 320000
19000x = 304000
x = 304000 / 19000
x = 16
In 16 years the populations of the suburb and the city be equal
Answer:
The correct answer will be "Division".
Step-by-step explanation:
- The procedure represents numerous values requiring something like a conjugate to have been done becomes division, since the denominator conjugate multiplies the numeric values including its quotient to represent the quotient of several complex numbers throughout the standard language.
- It is indeed a method used to separate a set of items across equal proportions.
Answer:
5) 35 / 100 = X / 74 X = 2590 / 100 = 25.9
or .35 * 74 = 25.9
6) 78 / 95 = X * 100
X = 7800 / 95 = 82.1 %
or X = 78/95 * 100 = 82.1 %
7) 60/100 * X = 28
X = 2800 / 60 = 46.7
Or .6 * X = 28
X = .28 / .6 = 46.7
