7. Draw a figure to represent this situation.
Write and Solve Equations to Find Measurements
ALGEBRA Find the value of x and ST if T is between S and U, ST = 7x, SU = 45, and TU = 5x – 3.
Draw a figure to represent this situation.
ST + TU = SU Betweenness of points
7x + 5x – 3 = 45 Substitute known values.
7x + 5x – = Add 3 to each side.
12x = 48 Simplify.
