In 1920, a woman had 4 daughters. In 1950, each daughter had 3 daughters. In 1980, each of their daughters had 3 daughters. Finally, in 2010, each of their daughters had 3 daughters. How many daughters were born in 2010? Explain how you determined your answer.

The length of a rectangle is x times the square root of 100. the width is one-half y more than three-halves x. given that the area of the rectangle is 125 cm2, which equation could represent the rectangle in terms of x and y? a) 5xy − 15x = 125 b) 5xy + 15x = 125 c) 15x2 − 5xy = 125 d) 15x2 + 5xy = 125

Which equation could represent the relationship shown in the scatter plot? y=−3x−2 y=−3/4x+10 y=−2/3x+1 y=9x−12 scatter plot with x axis labeled variable x and y axis labeled variable y. points go from upper left to lower right.

Solve for the equation. 4x - 13 = 2x + 9
