Maria found the least common multiple of 6 and 15. her work is shown below.

multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . .
multiples of 15: 15, 30, 45, 60, . .

the least common multiple is 60.

what is maria’s error?
maria listed some values that were not multiples.
maria listed factors of each number instead of multiples.
maria should have multiplied 6 and 15 to find the least common multiple.
maria selected a multiple that is not the least of the common multiples.

[10 points, algebra 2]according to my answer key the restrictions are -1 and 4. but why not positive 1?

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?

Evaluate the function , when d = {9, 15, 30}. r = {5, 7, 12} r = {6, 10, 15} r = {6, 10, 20} r = {5, 12, 20}
