Question

Ayana wants to determine the sum of point T and -1 1/2. Explain how Ayana could use the number line above to find the sum of point T and -1 1/2. Include the sum in your explanation.

a. Ayana should add T and -1 1/2 on the number line to find the sum.
b. Ayana should subtract T from -1 1/2 on the number line to find the sum.
c. Ayana should find the midpoint between T and -1 1/2 on the number line to find the sum.
d. Ayana should multiply T and -1 1/2 on the number line to find the sum.

Answer 1

Ayana should subtract -1 1/2 from T on the number line to find the sum.

Step-by-step explanation:

Ayana wants to determine the sum of point T and -1 1/2. To find the sum, Ayana can use the number line. Since -1 1/2 is a negative number, Ayana should subtract -1 1/2 from T on the number line to find the sum. This can be done by moving T to the left by the distance of -1 1/2. The sum of point T and -1 1/2 can be represented as T - (-1 1/2) or T + 1 1/2.
