Now that Joseph finally has his own bike, he plans to take good care of it. His local bike store recommends using about a teaspoon of oil to clean the chain every 300 miles. If Joseph rides an average of 200 miles per month, how many months should he expect a 4-fluid-ounce bottle of oil to last?

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
