A number line is drawn left to right with integers spaced 1 centimeter apart. An ant crawls onto the number line at +3. It then crawls 1.5 centimeters left, 4.9 centimeters right, and 7.6 centimeters left. Where is the ant on the number line now?
1 answer:
Answer:
-1.2 cm
Step-by-step explanation:
Let's figure out where the ant is after each step.
Step 1
Start at +3.0
Move left <u> - 1.5
</u>
Now at +1.5
Step 2
Start at +1.5
Move right <u> + 4.9
</u>
Now at +6.4
Step 3
Start at +6.4
Move left <u> - 7.6
</u>
Now at -1.2
The ant is now at -1.2 cm .
