1. Carlos has 4/5 of a tank of gas in his car. He uses 1/10 of a tank per day. How many days will the gas last him before he needs to refill his tank.

2. Sarah has 2/3 gallon of blue paint and 7/12 gallon of red paint. If she has a total of 2 1/8 gallons of paint, how many gallons are neither red nor blue paint.

How does number one go by total divided by part but number 2 doesn't.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
