Jimmy is a tutor in the science club. He charges $40 per semester to privately tutor other students and an additional $10 for home visits to help him pay for
gas. If Jimmy made less than $80 this semester for tutoring 1 student, which
inequality can be used to determine how many times he visited the student's
home?
I JUST NEED THE INEQUALITY EQUATION

A. 40 + 10x < 80
B. 40x+10 < 80
C. 50x < 80
D. x/10 + 40 < 80

Match the equivalent expressions. x - 3y + 12 12 - 3y - 2x + x + 2x 3x + 2y - 2x + y + 12 3y + 12 3x + y - 12 4y + 3y + 3x - 6y - 10 - 2 x + 3y + 2x - 3x + 7 + 5 x + 3y + 12 5 + 2y + 7x - 4x + 3y - 17

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?
