- 1)The sum of three consecutive multiples of 4 is 444. Find these multiples. [This is a problem on linear equations in one variable] 2.State the steps you will take to transform 3x + n = 7 to x = (1/3)[7- n]arrow_forwardOn the basis of data from 1990 to 2006, the median income y in year x for men and women is approximated by the equations given below, where x = 0 corresponds to 1990 and y is in constant 2006 dollars. If these equations remain valid in the future, in what year will the median income of men and women be the same? Men: Women: -231x+2y=60,623 - 830x + 3y = 49,894 The median income of men and women will be the same in the yeararrow_forwardIf x=ad/(c-d), solve for y in terms of a, c, d, and r. r(1-x)(a+x)-cy=0arrow_forward
- Suppose C = 45+ 0.5t and L = 9 +2.5t represent the population (in thousands) of two cities, Clarksville and Lanesville, respectively. Determine the number of years it will take for their populations to be (a) equal, and (b) for Clarksville to have twice as many inhabitants as Lanesville. Also report the population of the towns for each situation. (a) In how many years will the population of Clarksville equal that of Lanesville? Number years What will be their populations?
