<span>Twenty-five percent of his friends have 13 or more baseball cards.

He is wrong. we are only looking at the last number which is 4
if we tripple 4 or 4*3 we get 12 which ends in 2, not 9
y -3x =1
add 3x to each side
y = 3x+1
The coefficient for x is 3 and the constant is 1
The equation would be 63500-700x=P, where 63500 is the original population, -700 is the amount the population decreases each year, x is the number of years, and P is the total population.
To answer the second part of the question, plug in 53000 for P and solve for x:
63500-700x=53000
<em>*Subtract 63500 from both sides*</em>
-700x=-10500
<em>*Divide both sides by -700*</em>
x=15
It would take 15 years for the population to drop to 53000.
Hope this helps!!
