Set up a proportion pages/pages= minutes/ minutes 7/175=5/x Note: x is the unkown variable or how long it will take him to read a 175 page book. --Now do the math-- or cross multiply-- 7(x)=175(5) reduce it down 7(x)=875 divide both sides by 7 in order to get variable x alone x=125 So it will take Jose 125 minutes to read the entire 175 page book.
∠ ABD and ∠ DBC are linear pairs ∴ ∠ ABD +∠ DBC = 180 ∴ 5(2X+1) + 3X+6 =180 solve for x ∴ x = 13 ∴∠ ABD = 5(2X+1) = 5(2*13+1) = 135 ∠ DBC = 3x+6 = 3*13+6 = 45
∠ ABD and ∠ EBC are vertical angles ∴ ∠ ABD = ∠ EBC = 135 ∴ y +135/2 = 135 ∴ y = 135/2
The <span>statements that are true: --------------------------------------</span><span> C.) x=13 E.)measure of angle EBC =135 F.) angle DBC and angle EBC are linear pairs
