C I think I hope I’m right but it should be c
Set up a proportion
160 mi/ 3.2 hrs ≈ 300 mi/x hrs
cross multiply and solve for x and you get x≈6
It will take them 6 hours
3x+7=3x+2 (cancel equal terms)
7=2 ( the statement is false)
Answer:
38cm is the circumference
Explanation:
circumference = diameter x 3.14
diameter = 12
circumference = 3.14 x 12 = 37.68
Now we need to round to the nearest whole
36 and 38 are the nearest wholes to 37.68. We need to minus and then find smallest difference between the numbers; meaning the smaller the difference the closer it is.
37.68 - 36 = 0.68
38 - 37.68 = 0.32
37.68 is more closer so we can round this to 38.
