Answer: (8,8)
Step-by-step explanation:
First you need to get a x or y by itself.
I choosed to get y by itself since it would be faster.
-2x + y = -8 (first get -2x to the other side so add 2x)
y = -8 + 2x (then you want to insert that to the other equation)
-x + 4( -8 +2x) = 24 -> -x -32 + 8x = 24 -> 7x -32 = 24
(add 32 to the other side)
7x = 56 (divide 7 to 56 to get x) x = 8
now insert into the other equation
-2( 8 ) + y = -8 -> -16 + y = -8 ( move -16 to the other side, so add 16)
then you get your answer, y= 8
Answer:
While Solving a proportion problem you multiply the x and the numerator or denominator. (Diagonal from the x)
Step-by-step explanation:
Answer:
7,744 (96.8% of population at the beginning of the year)
Step-by-step explanation:
Population of the city at the beginning of the year = 8000people
Yearly percentage decrease = 3.2%
This means at the end of the first year the population reduces by 3.2% which gives 3.2%of 8000
= 3.2/100 × 8000
= 3.2 × 80
= 256
This shows that the population decreases by 256 at the end of first year.
To get the 1year percentage change in population, we will subtract the percentage decrease in Population from the initial population to give;
8000 - 256
= 7,744
7,744population remains after 1year wish is (100-3.2)% i.e 96.8% of the population at the beginning of the year.
