Let's make an equation to show how to get how many people were in 105,000.
But, with a decrease, you have to decrease it from 100.
100-12.5
87.5
So it will be 87.5 of what it was previously. Now let's get to the equation.
.875x=105,000
Let's divide each side.
105,000÷.875
120,000
Let's check if this was a 12.5% decrease.
120,000×0.125
15,000
120,000-15,000
105,000
So the population of 2010 was 120,000 people.

ok i will teach all just chat me
Step-by-step explanation:
ok
Add 2 to both sides
a>4+2
simplify 4+2 to 6
a > 6 is the answer
Answer:
solution is (3, - 1)
Step-by-step explanation:
given the 2 equations
x + y = 2 → (1)
x - y = 4 → (2)
Adding the 2 equations term by term will eliminate the y-term
(x + x) + (y - y) = (2 + 4)
2x = 6 ( divide both sides by 2 )
x = 3
substitute x = 3 in either (1) or (2) for y
(1) → 3 + y = 2 ( subtract 3 from both sides )
y = 2 - 3 = - 1
solution is (3, - 1)
