Pls tell me I am not the only person who sucks at math :| *pls answer correctly tho. it'd be nice O_Oyes brainlest and ect.. are included*

Consider this equation and the steps taken to solve it.

–9(a – 5) = –18 (distribute)
–9a + 45 = –18 (subtract 45)
–9a = –63 (divide by –9)
a = 7

What steps might you take to verify the solution? Check all that apply.

A) Substitute 7 for a.
B) Pick any value for a and substitute.

C) Simplify the equation after substituting the value for a.

D) Verify that a = 7 is correct when the result is a true statement.

E) Verify that a = 7 is correct when the result is a false statement.

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
