Model the male and female data algebraically with separate linear equations of the form y=mx+b [use the 1960 and 2010 ordered pairs(with x-coordinates 0 and 50) to compute the slopes]

Which is the most efficient first step to solve x in the equation 3.7x - 18 = -4.3x -34 a. add 3.7x to both sides of the equation. b. add 4.3x to both sides of the equation. c. subtract 18 from both sides of the equation. d. subtract 34 from both sides of the equation.

What is the measure of ac? 5 units 13 units 26 units 39 units 3x- 2b 6x + 9

Complete the solution of the equation. find the value of y when x equals to 6 4x+y=20
