You have to find the equation that would fit the situation which would be 57,000+800x= population. Then the difference in the years from the year you are trying to figure out to 1980 is plugged in for x. so you would do 2015-1980=35 you would then plug in 35 of x in the equation. 57,000+800(35)=85,000.
The answer is C because complimentary is equal to 90 so 24+66 equals 90 and 34+56 equal 90
-27 = -3p + 15 - 3p
Combine like terms.
-3p -3p = (-3-3)p = -6p
-27 = -6p + 15
Subtract 15 from each side to get the variable term on its own.
-27 - 15 = -6p + 15 - 15
-42 = -6p
Divide each side by -6 to find p.
p = -42 ÷ -6 = 7
Y= -x + 2 and y= 3x - 4
As these both equal y, you know that they both equal each other so
-x + 2 = 3x - 4
Third option :)
