ACT Problem Melissa had 4 fewer apples than Marcia. Then, she gave 3 apples to Marcia. Now, how many fewer apples does Melissa have than Marcia? Let Melissa have 10 apples. So, we start with the following: Melissa Marcia 10 14 Now, we Melissa gives 3 apples. 7 17 17 -7 = 10. So, Melissa currently has 10 fewer apples than Marcia.

ACT Problem Going back: Melissa had 4 fewer apples than Marcia. Then, she gave 3 apples to Marcia. Now, how many fewer apples does Melissa have than Marcia? A. B. C. D. E. 0 3 4 7 10

Abstract Border Design

Classifying Triangles

Classifying by Sides A triangle is scalene if no sides are the same length. A triangle is isosceles if exactly two sides are the same length. A triangle is equilateral if all sides are the same length.

Classifying by Angles A triangle is acute if all the angle of the triangle are acute. A triangle is right if it has one right angle. A triangle is obtuse if it has one obtuse angle. A triangle is equiangular if all the angles are the same.

Triangle Angles All the angles of a triangle equal 180°. 180 – 57 – 36 = 87 a = 87°

Classifying Triangles Sides Scalene, Isosceles, Equilateral Angle Acute, Right, Obtuse, Equiangular
