Isabel found three pieces of cable in her tool drawer. Here are their lengths (in meters).

10.43 ,13.2 ,9
What is the total length of the three pieces?

question 2: Lashonda needs to drive 20 miles to work. So far, she has driven 2.6 miles. How many more miles must she drive?

1. Add the three numbers.

2. Subtract: 20 - 2.6 = ?

To find the total length of the three pieces of cable, you need to add up their lengths.

The three lengths are given as 10.43 meters, 13.2 meters, and 9 meters.

To calculate the total length, add the three lengths together:

10.43 + 13.2 + 9 = 32.63

So, the total length of the three pieces of cable is 32.63 meters.

Now, let's move on to the second question.

Lashonda needs to drive 20 miles to work, and she has already driven 2.6 miles.

To find out how many more miles she must drive, subtract the distance she has already driven from the total distance.

20 - 2.6 = 17.4

So, Lashonda must drive 17.4 more miles to reach her workplace.
