Aclassmate asks you to him check his math problem. he has been working on the following equation: 7x - 5 = 10 +4x. he claims the answer to this problem is 4. which of the following situations models the best way to determine if your
classmate's answer is correct?
a) solve the problem for yourself, and see if your answer matches your classmate's answer.
b) replace the variable in the equation with 4 simplify each side of the equation to determine whether or not it is a true statement.
c) divide both sides of the original equation by 4.

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?
