Answer:
the previous population was 62,000.
Step-by-step explanation:
The current population of a city = 83,700
The population of a city has increased by 35% since it was last measured.
We have to calculate the previous population before increasing 35%.
Let the previous population be p
p +(35% × p) = 83,700
p + 0.35p = 83,700
1.35p = 83,700
p =
p = 62,000
Therefore, the previous population was 62,000.
Answer:
14.285% or 14.3% if rounded to the nearest one decimal place.
Step-by-step explanation:
4 ÷28 × 100
2x + y = -3
x - 2y = -4
2x + y = -3
2x - 4y = -8
----------------
5y = 5
y= 1
2x + y = -3
2x + (1) = -3
2x = -4
x = -2
Solution: x = -2, y = 1
