ScanSolve AI Tutor · Accepted Answer

Here are the addition and subtraction sentences for each number line: 1) Step 1: Identify the starting point, direction, number of hops, and ending point. The starting point is 5. The hops move forward (to the right). There are 7 hops. The ending point is 12. Step 2: Write the addition sentence. 5 + 7 = 12; 5 + 7 = 12 2) Step 1: Identify the starting point, direction, number of hops, and ending point. The starting point is 1. The hops move forward (to the right). There are 15 hops. The ending point is 16. Step 2: Write the addition sentence. 1 + 15 = 16; 1 + 15 = 16 3) Step 1: Identify the starting point, direction, number of hops, and ending point. The starting point is 7. The hops move forward (to the right). There are 8 hops. The ending point is 15. Step 2: Write the addition sentence. 7 + 8 = 15; 7 + 8 = 15 4) Step 1: Identify the starting point, direction, number of hops, and ending point. The starting point is 16. The hops move backward (to the left). There are 9 hops. The ending point is 7. Step 2: Write the subtraction sentence. 16 − 9 = 7; 16 − 9 = 7 5) Step 1: Identify the starting point, direction, number of hops, and ending point. The starting point is 12. The hops move backward (to the left). There are 7 hops. The ending point is 5. Step 2: Write the subtraction sentence. 12 − 7 = 5; 12 − 7 = 5
