40/1 is the same 80/2 120/3 160/4
Chuck travels at A) 30 mph
since chuck and dana travelled at the same amount of time (2 hours), dana travels at 26 mph, which is 4 mph less, and chuck travels at 30.
step by step you can ask about anything you dont understand
Tan 34 = 12/x and then uhm, put 12/tan34 into ur calculator
3+5=8 24÷8=3
3×3=9 muffins 5×3=15-pizza
I hope this helped!!!:)
