Patricia is writing statements as shown below to prove that if segment ST is parallel to segment RQ, then x = 35:
Statement Reason
1. Segment ST is parallel to segment QR. Given
2. Angle QRT is congruent to angle STP. Corresponding angles formed by parallel lines and their transversal are cong
ruent.
3. Angle SPT is congruent to angle QPR. Reflexive property of angles
4. Triangle SPT is similar to triangle QPR. Angle-Angle Similarity Postulate
5. ? Corresponding sides of similar tri
angles are in proportion.

Which equation can she use as statement 5?

Options
A) x:15 = 28:40
B) 28:12 = x:(x + 15 )
C) x + 15 = 28 + 12
D) 28:40 = x:(x + 15)

Write two subtraction equations that are equivalent to 5 + 12 = 17.

Which number line correctly shows 0.8 + 0.3?
