In the figure below, angle y and angle x form vertical angles. angle x forms a straight line with the 50° angle and the 40° angle.

write and solve an equation to determine the measure of angle y.

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Match the scale and the actual area to the area of the corresponding scale drawing. scale: 1 inch to 4 feet actual area: 128 square feet scale: 1 inch to 7 feet actual area: 147 square feet scale: 1 inch to 8 feet actual area: 256 square feet scale: 1 inch to 5 feet actual area: 225 square feet area of scale drawing scale and actual area scale drawing area: 3 square inches arrowright scale drawing area: 8 square inches arrowright scale drawing area: 4 square inches arrowright scale drawing area: 9 square inches arrowright

Solve the equation. 2x - 8(x+1)= 6(2x - 3)
